What engines are installed on Volkswagen. Volkswagen Polo sedan engine, technical characteristics of Volkswagen Polo engines

4 cylinders, 8 valves, direct injection – the robust engine also offers some innovative design changes. The disadvantages include perhaps not economical fuel consumption.

Owners include floating speed when the engine is idling as a typical malfunction for the model. This nuisance can be eliminated by cleaning and adjusting the throttle valve.

Overall, 1.6 MPI “runs” 500 thousand km without major interventions and does not suffer from birth defects.

1.4

This engine appeared back in 1991 with the VW Golf III. Back then it was a cast iron block with one injection point and a modest 60 horsepower. But the longevity and reliability of this model led to its improvement. Over time, the manufacturer has already offered a 16-valve version instead of the 8-valve, a multipoint injection system and even an FSI version.

Compared to the first 1.4, versions with 16 valves 1.4 MPI developed 75-101 hp. But the version with a chain instead of a timing belt, 1.4 FSI with 86 hp, is considered unsuccessful.

The 1.4 engine of this generation was installed in the Audi A2; Seat Arosa, Ibiza, Leon, Cordoba, Toledo; Skoda Fabia, Octavia, Roomster; Volkswagen Golf 3, 4, 5, Polo 2, 3, 4, Fox, Lupo. But such an engine can no longer be found in modern golf-class models.

In general, according to reviews from owners, the 1.4 engine is distinguished by its simplicity of design and unpretentious operation. TO typical problems engine problems include freezing of the crankcase gas exhaust channel at low temperatures, wear of the steering hydraulic compensators and failure of the Hall sensor. The owner is in trouble only in case of CPG wear– this calls for an engine overhaul. The rest can be successfully dealt with, especially since repairing this engine is inexpensive - that’s why its owners love it so much.

1.4TSI

Under common name hidden 2 generations EA111 And EA211 and their modifications. Since 2005, the 1.4 TSI has been installed on the VW Golf GT. Sequential supercharging gave the engine 170 horsepower. Soon a 140-horsepower modification of the engine was released, and a little later the mechanical compressor was removed, leaving only the pipe and a “modest” 122 hp.

In 2012, the EA111 appears and is replaced by the EA211 series with a different design. The proven EA111 can thus be found in cars until 2012: Audi A1, A3; Seat Ibiza, Altea, Leon; Skoda Fabia, Octavia, Superb, Yetty; Volkswagen Golf 5, 6, Jetta 3, 4, Polo, Passat B6 and SS, Sharan, Turan, Tiguan.

The 1.4 TSI's good reputation is ensured by its torque, efficiency and excellent dynamics.

As for typical complaints from owners, we can highlight timing chain stretching and piston failure. The latter is different from the first versions of the engines (160 and 170 hp), so to purchase the 1.4 TSI it is better to consider the derated versions.

1.2TSI

Version 1.2 with a direct injection system saw the world in 2009. Volkswagen Golf 4, Jetta 4, Polo, Caddy, Turan got this engine; Skoda Octavia, Fabia, Yetty, Roomster; Seat Altea, Ibiza, Leon, Audi A1 and A3.

The designers' goal was to offer a worthy alternative 1.6 MPI, smaller in volume and with reduced fuel consumption. 8 cylinder head valves, the presence of a turbine with an output of 105 “horses” are the main characteristics of the model. Previously, the line included an 85-horsepower 1.2 TSI.

In 2012, the timing chain was replaced with a belt.

In general, this engine fulfilled all the assigned tasks: efficiency with optimal performance - torque of 160 and 175 Nm in the range of 1500-4000 rpm.

As for the operational problems identified by the owners, in the first series this timing chain drive. In some cases, uneven operation of the engine at idle is noted, which can be solved by reflashing the computer, and failure of the turbine, or more precisely, the system for regulating its pressure.

On average, a 1.2 TSI lasts 250 thousand kilometers without major repairs.

1.2

Found in the smallest cars of the VAG family: Seat Ibiza, Cordoba; Skoda Fabia, Rapid, Roomster; Volkswagen Polo 3, 4, Fox.

The engineers' decision to give life to a three-cylinder engine is associated with reducing production costs. The timing chain, which all in-line 1.2 6V and 1.2 12V received, was supposed to outperform the belt in terms of operation. But in reality, this decision turned into a problem: repairing the chain drive was more expensive, and its service life was identical to the belt service life. Over time, the issue with a defective chain tensioner, due to which it jumped several links, was resolved.

Another point that causes dissatisfaction among owners is that the positioning of the ultra-high torque of the 1.2 engine does not correspond to reality. The six-valve version develops only 55 hp, while the 12-valve version is more fun: 64 and 70 “horses”. Torque reaches only 108 and 112 Nm/3000 rpm. Hence the restriction of the operation of cars with such internal combustion engines within city limits.

As for fuel consumption, it is 1.2 comparable to gasoline consumption 1.4. Only the latter has one more cylinder, which eliminates a number of operational issues.

Typical problem with petrol 1.2 - failure of the ignition coils. This can be easily determined by strong vibration, misfires and unstable engine operation.

Despite the design flaws, VW did not abandon the idea of a three-cylinder engine and in 2012 even boosted it for the Skoda Rapid, giving it 75 hp. and released modification 1.2 with a direct injection system for the Polo.

Hidden functions of your Audi - check.

Volkswagen is one of the most popular used cars not only in our market, but also abroad. Most widespread received Golf and Passat models. They share their powertrains with premium brand leader Audi and another global bestseller, the Skoda Octavia II.

The average buyer of used cars is primarily interested in the condition of the engine and the possible financial costs of repairing it. Therefore, when describing motors, the main attention is paid to operating costs, common faults and design flaws.

1.4

Short description:

4-cylinder;

8 or 16 valve;

Multipoint distributed or direct injection;

The engine debuted in 1991 with the third generation Volkswagen Golf and developed only 60 hp. It was a cast iron block with a crankshaft on five bearings. Initially, the power unit had only one injection point and one overhead camshaft in the cylinder head. The motor is still in production. However, its durability and reliability contributed to further improvements. There were: a 16-valve version, multi-point fuel injection and even an unsuccessful FSI modification with direct injection and a timing chain. All other versions had a timing belt drive.

Thanks to its simple design, the power unit can be modified to run on liquefied gas without much difficulty. True, sometimes this results in speed bumps and increased oil consumption.

Note. The Skoda Fabia used two types of engines with a displacement of 1.4 liters: a 16-valve engine developed by VW and an 8-valve MPI - a descendant of the units of the ancient Skoda 105/120 with a camshaft in the housing.

The huge popularity of the motor makes it easy to identify common problems. It is devoid of significant design flaws, unlike some of its components. Be careful with FSI engines - the timing chain can sometimes cause trouble.

Freezing of the crankcase ventilation duct

An unsuccessful design of the crankcase ventilation system leads to the fact that in severe frosts (below -15 degrees) the gas exhaust channel freezes. This leads to an increase in crankcase pressure and a significant reduction in the amount of oil supplied to lubricate the engine. Mechanics recommend changing the crankcase gas exhaust duct every three years - before winter. The cost of such an operation is only 25-30 dollars.

Wear of hydraulic valve compensators

If the engine starts to chirp at idle like a diesel engine, then most likely it’s time to change the hydraulic valve compensators. But most owners ignore this problem by adding thicker oil.

Piston ring wear

The 1.4-liter unit normally consumes little oil. But if its consumption increases to 1 liter per 1000 km, then the intervention of a mechanic will be required. The most common cause of this is worn piston rings. In such a situation, it is better to find a new engine. Motorists do not recommend dismantling the crankshaft, because the modern 1.4 has a soft aluminum block that is easily deformed.

Hall sensor failure

Does the engine stall after getting into a puddle? Water may have entered the crankshaft position sensor. Only replacement will help.

Summary

The main advantage of the 1.4-liter unit is the absence of serious disadvantages. It does not impress with either dynamics or efficiency, but it is always ready to work, tolerates the transition to gas well and, above all, is inexpensive to repair.

As an alternative, you can consider a radical option - a 1.4-liter turbodiesel. However, it is difficult to love it for its excessive noise.

1.2

Short description:

3-cylinder;

6 or 12 valves;

Direct or distributed injection.

Fewer cylinders means fewer moving parts, which means less internal resistance and lower production costs. That is why Volkswagen, when developing an engine for the smallest cars, decided on an in-line three-cylinder engine. To reduce operating costs, a timing chain is used. But it soon became clear that such savings were an illusion. The chain did not last longer than the belt.

This engine was positioned as having very high torque. In the Skoda line, it received the designation HTP - High Torque Performance (from English - engine with high torque). But in practice this feature has not been confirmed. In 2012, a reinforced 75-horsepower version of the engine appeared for the Skoda Rapid and a modification with direct fuel injection for the VW Polo.

Operation and typical malfunctions

Timing chain noise

For a long time, VW could not fix the chain tensioner defect. As a result, the chain could jump several links. In fact, it had to be changed after 60,000 km. The cost of such work is about $250.

Burnt out ignition coils

If the engine begins to shake violently, starts with difficulty and suddenly stalls, then the ignition coils are most likely faulty. Replacing one coil will cost $30.

Summary

The engine is suitable for undemanding drivers who use the car every day. The engine successfully transfers the transition to gas. The malfunctions are not very serious, although they can sometimes immobilize the car.

As an alternative, you can consider a 1.4-liter petrol unit. It consumes about the same amount of fuel.

1.2 TSI

Short description:

4-cylinder;

8-valve;

Turbocharging;

Designed for small and compact cars.

The 1.2 TSI engine went into production in 2009 and was assembled at Skoda sites. Its task is to replace the 102-horsepower 1.6 MPI. The 1.2 TSI provides lower fuel consumption by an average of 0.9 l/100 km. The engine uses an 8-valve cylinder head, which is cheaper to produce. Turbo engine output is 105 hp. During the production process, a less loaded 85-horsepower version with a torque of 160 Nm instead of 175 Nm was also assembled. Due to numerous problems with the timing chain drive, at the end of 2012 the manufacturer modernized the engine design, equipping it with a belt drive. The new engine was only included in the latest models, while the old ones were still equipped with a motor with a timing chain drive.

The simple design of the unit was intended to reduce weight, production costs and disposal costs. These tasks were completed. The 1.2 TSI boasted good economy with an acceptable level of performance.

Due to direct fuel injection, it is quite problematic to “make friends” of the engine with gas equipment. True, some services offer similar solutions, but in practice, switching to gas provokes problems. Therefore, it is better to refrain from such modifications.

Operation and typical malfunctions

The 1.2 TSI (paired with the 1.4 TSI) is the new generation EA211 engine, which uses many solutions to help save fuel. They turned out to be effective. Even fairly large cars with 1.2 TSI, such as the Skoda Octavia, consume only 7 liters per 100 km.

Timing faults

1.2 TSI of the first series are equipped with a timing chain drive. The hydraulic chain tensioner causes problems. Skoda Octavia III, Skoda Rapid and VW Golf VII are equipped with a new engine with a timing belt drive.

Failure of the turbocharging system

Many copies have problems with turbocharging. They do not affect the turbine itself, but only affect the pressure control system, which is integrated into the supercharger. Consequently, if there is a malfunction, the entire turbocharger has to be replaced. As a rule, problems arose and were resolved during the period warranty service. The turbocharger was replaced with a modernized one, theoretically devoid of shortcomings.

Rough idle

Some owners have reported rough idling. The problem was solved by downloading a new software for the engine control unit.

Volkswagen Polo - since 11.2009.

Summary

The engine is very economical. After solving the problems with the timing drive and turbocharging, it will not cause trouble. Unfortunately, due to the small displacement, you should not count on the durability that older motors have. Guaranteed mileage without serious faults is more than 250,000 km. The power unit is not suitable for conversion to gas.

1.4 TSI

Short description:

4-cylinder;

16-valve;

Direct fuel injection;

Turbocharging;

Designed for small, compact and mid-class cars.

Under the name 1.4 TSI there are two generations of EA111 and EA211 units and many modifications. The 1.4 TSI was launched in November 2005 for the Volkswagen Golf GT. Thanks to sequential charging (mechanical compressor and turbocharger), it developed 170 hp. Six months later, its 140-horsepower modification appeared. A year later, in May 2007, a version without a mechanical compressor entered the market - derated to 122 hp.

In February 2012, the 1.4 TSI was replaced by the EA211 series engine. The new unit received a completely different design. Only the distance between the cylinders remained unchanged. There are still few of these motors on the secondary market.

However, the EA111 is still installed in models introduced before the successor was introduced. It provides high productivity, an impeccable work culture and acceptable fuel consumption. Cost-effectiveness is achieved through precise fuel dosage, as well as a number of technical solutions.

Operation and typical malfunctions

Since its introduction, the 1.4 TSI has captivated us with its excellent performance and very low fuel consumption. Versions with sequential supercharging have fantastic dynamics, while for the Golf V the consumption is about 8 l/100 km. In the case of engines without a mechanical compressor, fuel consumption can be maintained at 7.5 l/100 km.

Piston destruction

The defect is typical for the first 160 and 170 hp engines. Heavy loads and a lean mixture caused the pistons to overheat. As a result, many engines were seriously damaged and the piston needed to be replaced. Similar problems were not observed in weaker versions with 122 and 125 hp.

Valve train chain

Most owners of cars with 1.4 TSI have encountered problems caused by the timing chain. Poor quality chain material led to its stretching, and the hydraulic tensioner at some point chose its course. Neglecting noise in the timing drive area led to the chain jumping, and the pistons “met” the valves. The shortcoming was eliminated in 2012 by introducing a new generation engine - with a timing belt.

Summary

The engine turned out to be both economical and dynamic. Given the problems with the pistons, it is not recommended to purchase the first versions with double supercharging (160-170 hp). The engine will be a good alternative to the diesel 1.9 and 2.0 TDI. It is not suitable for installing gas equipment. As an alternative to the 1.4 TSI in terms of dynamics and fuel consumption, you can consider the 2.0 TDI.

1.8 T

Short description:

4-cylinder;

20-valve;

Multipoint fuel injection;

Turbocharging;

For compact and mid-size cars.

The 20-valve 1.8-liter turbo engine debuted in 1995 in the Audi A4. Under the designation 1.8 T there were three families of engines. Initially these were twins with varying degrees of boost: 150 / 180 hp, 210 / 225 hp. In 2002, modernized versions with a capacity of 163 and 190 hp appeared.

The 1.8 Turbo pioneered a completely new VW Group philosophy regarding gasoline engines. He ushered in the era of so-called downsizing, which involves obtaining good performance from a small displacement through the use of turbocharging. The big advantage is moderate fuel consumption. An Audi A4 with such a unit consumes less than 8 l/100 km on the highway, and about 10 l/100 km in the city.

Thanks to the 20-valve cylinder head and turbocharger, it was possible to obtain very high torque even before reaching 2000 rpm. Thus, the engine combines the elasticity characteristic of turbodiesels with the operating culture of a gasoline engine. Despite the relatively developed engine control electronics, the 1.8 T was easy to convert to gas.

Engines of the 1.8 T family with a power of 150-180 hp. and 210-225 hp. differ not only in the turbocharger (KKK K03 of the first is weaker than KKK K04 of the second), but also in design. In particular, the mechanical strength of the 210-horsepower unit is so high that it can easily withstand an increase in power to 300 hp.

Operation and typical malfunctions

Compared to the previously common 2.0 V16 and VR6, the 1.8 T engine surprises with lower fuel consumption with the same power. Currently, an average consumption of 9-9.5 l/100 km is not sensational, but 20 years ago it was an excellent result. It is worth noting that the turbo engine has a very reliable design, capable of withstanding more than half a million kilometers.

The unit itself is free of birth defects. However, every year there are more and more copies with a mileage of more than 200,000 km. This is when oil consumption begins to increase, and later intervention in the gas distribution system may be required.

Chip tuning

A significant number of cars with 1.8 T have undergone chip tuning, which increased their power. If it was done correctly and the owner strictly followed the maintenance schedule, then there is nothing to worry about. But in most cases, the boost was performed by amateurs, which accelerates engine wear. For example, this often leads to overheating and, as a result, damage to the pistons or turbocharger.

Electrical faults

Among the randomly occurring failures, failures of the ignition coils, lambda probes or flow meter should be noted. However, compared to the malfunctions that occur in diesel engines, these are small things that are inexpensive to fix.

Summary

After 20 years of presence on the market of Volkswagen cars with a 1.8T engine, it must be admitted that this engine is one of the best. It combines good performance and acceptable fuel consumption, even by modern standards. It is reliable and free of design flaws.The engine has been in production for a long time and its roots go back to the first generation Volkswagen Golf. In its latest incarnation, starting in the mid-90s, it produces 101-102 hp. and has an aluminum block. All subsequent changes were minor and associated with stricter environmental standards. The 1.6 MPI with a capacity of 1595 cm3 should not be confused with another 1.6-liter naturally aspirated engine with a displacement of 1598 cm3, which has a completely different design.

The 1.6-liter unit is considered reliable and durable. It easily transfers to gas. Despite the 8-valve head, the engine offers a range of innovative solutions. For example, variable intake manifold geometry, a smart thermostat, energy-saving roller valve rockers, and secondary air supply to the exhaust system. Thanks to this, it was possible to meet the standards for the emission of harmful substances in exhaust gases with a margin. However, fuel consumption cannot be called low.

Operation and typical malfunctions

In older models of the 90s, a 101-horsepower version of the engine was installed, and in later models, a 102-horsepower version was installed. The engines are structurally similar, but have differences in details, and therefore some spare parts are not interchangeable.

The main feature of both engines is high reliability. The power unit easily overcomes the 500,000 km mark. An additional plus is ease of maintenance and repair. The average fuel consumption of a Skoda Octavia with this engine is about 8 l/100 km. By modern standards, this is not small.

The power unit has virtually no characteristic faults.

Floating idle speed

This flaw is not serious, but it is quite common. As a rule, it is possible to get rid of it after cleaning the throttle valve (dismantling is required) and adapting its operating parameters using a diagnostic computer.

Summary

The advantages of 1.6 MPI are high strength, excellent reliability and ease of switching to gas. Cons: moderate dynamics and relatively high fuel consumption.

An alternative could be the more economical 1.2 TSI.

In the CIS, the Volkswagen Polo Sedan is a well-known and quite popular model. The modern design and thoughtful solutions of the German concern Volkswagen allowed the budget sedan model to quickly get onto the list of real bestsellers. As you know, this car is assembled in Kaluga and is quite for a long time was produced with two reliable engines with a power of 85 and 105 hp.

However, after restyling, fans of the model were in for a real surprise, since in addition to new bumpers, a radiator grille, a trunk lid, improved sound insulation, a Golf steering wheel, LED headlights and a number of other improvements, the changes also affected the engine. Let's look at this in more detail.

Russian Polo Sedan engine

So, the new Volkswagen Polo Sedan, as before, is a model assembled in Kaluga, which has received improvements, including the engine. It's about about the CFN motor of the E211 series. Let us immediately note that the new power unit has become even more powerful and more economical. It is also noteworthy that the affordable sedan will receive units produced at the plant in Kaluga.

As before, the engine with a displacement of 1.6 liters has two stages. Only now it is no longer 85 and 105 “horses”, but 90 and 110 hp. In the first case, it is 155 Nm, maximum speed is 178 km/h, acceleration to hundreds is 11.2 seconds. Fuel consumption in mixed mode is 5.7 liters. The more powerful 110-horsepower version also has similar torque, while the maximum speed is already 191 km/h. Acceleration to hundreds on the version with a manual transmission is 10.4 seconds.

As for the automatic Polo sedan, with the new engine the car accelerates more slowly than the previous modification. Acceleration takes 11.7 seconds. The consumption is also slightly higher, which is 5.9 liters, but this is quite expected for an automatic transmission.

We also note that the Germans also offer a sports version of the Polo. We are talking about the Polo GT, which will receive a 1.4-liter engine with 125 hp. Also, this car will be equipped with a 6-speed robotic gearbox.

Let's return to the engine. The new Polo engine, or rather its 90 and 110 hp MPI versions, have become more modern and environmentally friendly. Main feature The upgraded versions of CFN are aluminum. Improvements have made it possible to speed up the warm-up of the engine, and the stove also starts working faster and more efficiently.

The sedan also received an expanded package, which provides improved preparation for winter conditions, which allows for confident and stable driving down to -30 and below.

Other parts and components did not receive any major changes. actually plastic, yet easily withstands high temperatures. The ignition system is non-contact, the oil pump has a pressure sensor, and it can be configured.

As for the resource, dealers voice a figure of 500,000 km. However, it should be understood that running-in, the quality of fuel, engine oil and maintenance, as well as operating features are factors that can greatly affect the service life, both for the better and for the worse.

You also need to pay attention to the question and other parameters in the event that the owner, for one reason or another, does not want to use the product that is offered official dealer as part of vehicle maintenance.

Naturally, as in any other case, the service life of any engine will greatly depend on the first kilometers. We are talking about compliance with all recommendations and regulations. In this case, the Polo sedan is no exception. And you shouldn't rely on the stated 2 or 3 year warranty.

Let's go further, for the exact and correct selection“consumables” will be greatly helped by the engine number and its markings. On a sedan from Kaluga, the serial number is located on the cylinder block under the body. Since the internal combustion engine is new, such information greatly facilitates the selection of engine oil, original spare parts or replacements from catalogs.

By the way, when choosing oils for this model, it is important to pay attention to the viscosity, which should be 5W30 or 5W40, as well as the tolerances. The oil must have approval VW 501 01, VW 502 00, VW 503 00, VW 504 00. ACEA A2 or A3 standard.

As for the manufacturer itself, some sources contain information that Castrol oil is poured into the Polo sedan engine during production. To change the oil, you need to buy about 4 liters; the manufacturer himself recommends pouring 3.6 liters into the engine, and the rest can be stored for topping up. This also needs to be monitored, as it can cause certain problems.

There is also information that power units undergo a so-called “cold run-in” of the engine right at the factory. Managers at car dealerships emphasize that it is for this reason that engines do not need additional running-in. However, in practice, experts pay attention to the fact that the engine, even the most modern one, still needs to be broken in.

The rules are quite simple: it is necessary to avoid driving without warming up, sudden starts, active braking, driving at a constant speed and at the same speed, driving in high gears, revs that are too high and too low, driving uphill in high gears, engine braking, towing a trailer. etc.

In other words, during break-in there is no need to “load” the engine for at least the first thousand km. Also, after the first thousand, the oil and oil filter need to be changed, and always use high-quality gasoline not lower than AI-95. Then the next oil change is expected at 3 thousand km, and the 10 thousand km mark can be considered the complete completion of the break-in. After this, the oil is changed again, and the engine can continue to be gradually loaded.

What's the result?

As you can see, if we talk about the Volkswagen Polo Sedan model, the engine after restyling has become more powerful and lighter. Thanks to the modernized cylinder head, which is cast from aluminum, as well as a number of other improvements, this engine is a real technological breakthrough for the plant in Kaluga and can quite rightly be considered an internal combustion engine made in the Russian Federation.

In practice, the pre-restyling version has proven itself to be a worthy competitor to other brands and models on the market, which also promises success and increased demand for the updated version of the Polo.

Finally, we note that like any other car, the Polo sedan has its pros and cons. Concerning previous versions CFN engine, frequent knocking of the pistons when cold was noted. Drivers also experienced that the throttle sensor wires chafed, cracked, problems appeared with crankcase ventilation, and the valve of this system “stuck.”

Another common complaint is problems with the power supply system. At the same time, malfunctions in the operation of the injector and the appearance, as well as knocking of hydraulic compensators, cannot always be considered a drawback of the engine, since the main reason is the quality of the fuel and oil, as well as unscrupulous maintenance.

It is also important to understand that other competing models, to a greater or lesser extent, have certain and often similar problems. However, Volkswagen in many cases takes into account certain shortcomings when modifying its engines. This means that the new CFN E211 engine in the Polo Sedan may well turn out to be a successful and reliable engine, which is devoid of many of the shortcomings and “illnesses” of its predecessor. However, strong and weak sides This internal combustion engine will only be revealed by practical operation.

Above are the dynamic characteristics and fuel consumption of a Polo sedan with a manual transmission; with an automatic transmission these figures are worse. So, acceleration to hundreds with automatic transmission takes 12.1 seconds, and fuel consumption increases by half a liter of gasoline.

A simpler motor VW Polo sedan 1.6 without a variable valve timing system on the intake shaft did not appear immediately, but after, in the struggle for customers, the manufacturer had to reduce the price of the car. A simplified version of the Polo sedan engine made the car a little cheaper, but the car's power also dropped. This engine has the factory index CFNB. The chain mechanism remains, but the cylinder head is now in a simplified form without an actuator for stepless timing change.

The 85 horsepower Polo sedan engine is installed only in combination with a manual transmission. A new power unit appeared in the company’s lineup in Russia only in the middle of last year. This is why there is not much information about the detailed structure and design of the engine, but the main characteristics are known.

Whatever Polo sedan engine you choose, it is a reliable, high-quality and durable unit. Of course, subject to careful operation and timely maintenance.

But we remind you that in 2016 the Polo sedan will be equipped with a new Russian-assembled 1.6-liter engine with a timing belt. The power of the units is 90 and 110 hp, that is, one option without a timing system, a more powerful one with a continuously variable valve timing system on the intake shaft.

The Volkswagen concern (VW) is one of the world's most powerful automakers after the legendary General Motors. It includes quite a few well-known car brands for which the company produces and installs engines.

Description of engines

Volkswagen engines offer power comparable to reliability. The range of power units is quite extensive. Engines produced by VW are considered the best in Europe and have a good reputation even in America. Thus, the company supplies engines not only to its own brand of cars, but also to such famous brands, like Audi, Skoda, Porshe, Seat, Beantly and even sports cars - Lamborgini and Bugatti.

As you can see, power units from the concern have become quite widespread throughout Europe. Volkswagen produces engines - naturally aspirated, turbocharged, diesel and others. All of them have gained great popularity among car enthusiasts from different countries due to their reliability.

The only drawback of engines is quite complex repairs, which can only be properly carried out at specialized automotive repair stations.

Volkswagen engine specifications

The standard Volkswagen engine is a four-cylinder unit with an overhead camshaft and water cooling.

Typically, the cylinder block, its head and pistons are made of aluminum alloy, and the crankshaft with three support bearings is made of forged stamped steel. Volkswagen engines have the following:

Gasoline engines

Among gasoline engines, it is difficult to single out one that will clearly win in the “most reliable engine Volkswagen." One of the most common engines among those that deserve to be considered the most reliable is a two-liter engine AWM with 140 hp. and torque 165 Nm . This engine has found its application in many Volkswagen cars, for example, Tiguan, Jetta and many others. The motor is notable for its excellent performance when driving on any surface. Among drivers there was also favorable word of mouth about this engine in the light that when using it it is convenient and comfortable to drive “uphill”, that is, it behaves well at high speeds, and is also quite good at idling after traveling a long distance.

It should be noted that the very first model of this engine appeared back in 1997, and since then this engine has transformed from a 1.2 liter engine into a completely powerful and reliable unit that you want to use. Among the obvious advantages of this unit, decent behavior, good dynamics, low fuel consumption (9.5 liters in the city), and relatively low repair costs stand out most clearly.

V6

Where would we be without a V6 engine in this rating? It was this engine that was considered the most reliable and desirable for drivers for a long time, thanks to its excellent characteristics. . First of all, the use of this engine guarantees excellent driving dynamics. Many fans of “driving” on the roads are very fond of this engine for its power - 170 hp, which allows you to accelerate quite well and quickly on the same Tiguan. Also, this power unit is quite attractive for those who often travel outside the city, because it is when driving on the highways that fuel consumption decreases - about 9 liters! In the city, consumption is also low - up to 7.5 liters.

Also, this engine cannot be called highly susceptible to breakdowns and malfunctions, because even if the car is not driven too calmly, the engine still behaves well and does not ask for anything extra. You can easily drive 150,000 km on it, changing only the oil.

Experts tried to find flaws in this engine, but could not get to the bottom of anything, because the engine is actually virtually ideal. Yes, some characteristics, for example, acceleration, could be improved so that it would be considered almost racing, you can, of course, reduce the cost of repair work, but in general it is simply beautiful!

Six-cylinder ABU

Among its six-cylinder counterparts, it is the model that stands out most clearly ABU with a volume of 1.8 liters . This motor is distinguished by a rather simple design, without adding complex elements. It is this fact that attracts the attention of drivers, especially those who have recently started driving a car, because this particular engine is quite easy to understand and understand how it works and how to carry out repair work on the engines yourself alone. The engine is well balanced, and this can be understood by the fact that during operation there is no vibration of mechanisms and components.
This engine became widespread in the same way as many others, on Golf and Tiguan cars.

This engine is classified as one of the so-called “millionaires” - engines that can travel about a million kilometers without serious intervention. This is where the reliability of this unit really shines! Everything would be fine, but there is one “but”: the cost of repair work cannot be called even average - the “normative” indicators that spontaneously occurred in the field of drivers for car repairs, this engine exceeds, which acts as a fly in the ointment. However, with such reliability, especially if you drive calmly and don’t “drive”, you can drive with it for 10-15 years without strain and quite calmly, naturally, changing consumables on time.

Tuning a Volkswagen engine is carried out by analogy with other engines. So, there are two options for modifying the engine: software (the most common) and mechanical (popularly - boring and installing additional spare parts).

By software modification we mean chip tuning, which in turn is divided into two subgroups: chip soldering and programming of the electronic engine control unit. The first option should only be carried out by professionals at a specialized car service center, since the process is quite specific and requires in-depth knowledge of automotive electricals.

As for the second option, most motorists do it themselves. To do this, you will need a little knowledge or instructions found on the Internet, a special USB-Car cable and a laptop. Accordingly, you need to download the software.

Software chip tuning aimed at improving the required engine characteristics. So, motorists usually choose one of two options: reducing consumption or increasing power. At the same time, balanced chip tuning is used less frequently.

The manufacturer does not recommend chip tuning of its engines. But, as practice has shown, this kind of recommendations does not influence the opinions of drivers and therefore the company has specially released several official firmware for its power units, which are called Stage+.

The latest version for engines today is version 5. It allows you to select the necessary parameters at the time of programming the electronic engine control unit.

Change of oil

Changing the oil is an essential operation for all engines. This is due to the fact that the lubricating fluid loses its technical and chemical qualities during operation. So, changing the oil in Volkswagen engines is quite simple if you follow the prescribed steps:

Contract engines

Any engine has a limited service life. After this resource expires, the car owner can:

do major renovation original engine;
purchase under contract in Europe or America and install a used engine.

The contract motor fully complies with the technical requirements and is a working unit dismantled from a similar car.

All contract engines undergo pre-sale inspection. Suppliers usually adjust all systems, do a test run and guarantee uninterrupted operation and a long service life.

In addition to contract engines, technical documents, attachments and installation elements are included.

So, a friend of mine owned an original Volkswagen Golf 1.4 with a manual transmission from 1994. The car was used all year round and at any opportunity. Sometimes it was loaded to the limit. The old car had difficulty making it up hills with an engine that was not very fresh. The car, although compact, is quite roomy. Over the five years of ownership, I changed the clutch basket and release bearing. I perceived timing belts and rollers as consumables. I planned to change the pistons and do a major overhaul of the engine due to oil consumption and low thrust. But on one of the trips I didn’t keep track of the temperature and overheated the engine so much that the head turned. Repairs amounted to almost 80 percent of the car's cost. This is a high price for a used car, not counting the time spent on repairs, searching for original parts or identical analogues. Back then we had no idea about the possibility of replacing the engine with a complete set. Now we wouldn’t even think twice about it.

The advantages of an engine purchased under a contract are:
