IN general view Mercedes engine is a long line of both petrol and diesel car engines different power and configurations.
One of the founders of the Mercedes-Benz automobile company (now the Daimler A.G. concern) was a German engineer, the creator of the world's first high-speed four-stroke single-cylinder power unit, Gottlieb Daimler. It was with him light hand All the company's cars, from the first day to the present, are powered by Mercedes engines.
A car is an integral attribute of modern society. However, the appearance of the first cars was preceded by the invention of engines. internal combustion(ICE), the history of which dates back to the distant 18th century. At the origins creation of internal combustion engines stood Gottlieb Daimler (Daimler-Motoren-Gesellschaft) and Karl Benz(Benz & Cie. Rheinische Gasmotorenfabrik in Mannheim).
Initially, both inventors were competitors, but due to the post-war crisis that affected all of Germany, they were forced to unite. The automobile manufacturing company they created (1926) for some time bore the name of its owners (Daimler-Benz), but later changed its name to Mercedes-Benz (Mercedes is the name of the daughter of one of the first clients of Daimler-Motoren-Gesellschaft).
As a result of its development, the company over more than 100 years of its existence has become the transnational concern Daimler A. G., which is currently one of the leaders in the global automotive industry. This was largely facilitated by the fact that the company, starting from the first days of its existence, developed and manufactured internal combustion engines for its cars.
Engines from Daimler A.G.
Mercedes engines that are produced Daimler concern A.G., amaze with their diversity. Among them you can find motors:
- with in-line or V-shaped arrangement cylinders;
- with the number of cylinders from 4 to 12;
- atmospheric versions;
- supercharged (compressor, turbine or twin-turbo);
- sports versions with increased power.
All Mercedes power units (both gasoline and powered by diesel fuel) are very different high reliability and operational durability.
Diesel engines
Mercedes diesel engines deserve special mention. Mercedes-Benz Company was the first in the world to install a diesel engine on a car. This happened in 1935, when Mercedes taxi 260 in the back of the W170 was aggregated diesel engine first generation OM 636 (power 43 horsepower).
Since then, no one will be surprised by a diesel engine in a passenger car. At the same time, Mercedes diesel engines, the design of which has been brought to perfection, have no equal in power and efficiency. These motors are constantly being improved. For example, in 1997 the 4-cylinder diesel engine OM 611 appeared with direct injection fuel Common Rail, designated CDI.
Then 5 (OM 612) and 6 (OM 613) cylinder power units were developed, various modifications of which develop power from 156 to 231 hp. With. The year 2008 was marked by the appearance of a new generation of Mercedes diesel engines, labeled OM 651. The power units of this series almost completely replaced engines of previous generations.
Gasoline engines
The Mercedes company has been producing gasoline engines since its founding. In their manufacture it is used a large number of technical innovations, which are designed to increase engine performance and reduce the amount of toxic substances in exhaust gases.
In addition, when developing new models, much attention is paid to reducing fuel consumption. The concern's specialists approach the introduction of new products very carefully. Thus, while working on the implementation of supercharging systems, the developers chose a compressor, with the help of which they can make a smooth increase in power without the unpleasant effects inherent in turbines.
First engine with mechanical compressor appeared in 1995. It received the designation M 111. Seven years later a more modern one was released power unit M 271 with power from 122 to 192 hp. With. (cylinder volume 1.8 l), equipped with a multipoint fuel injection system. This engine was manufactured from 2003 to 2005. You can recognize it by its CGI markings. The same engine was produced with a turbocharger, developing power up to 204 hp. With.
Since 2004, the M 272 V-shaped 6-cylinder power unit with multi-point fuel injection was launched into production. intake manifold. There are also versions with direct injection. It was first installed in Mercedes-CLS cars, and then in E-Class models in the back of a W212. In 2010, more than modern engine M 276, however, the M 272 engine is still produced by Daimler A. G. today.

Description
The M 272 power unit is a V-shaped 6 cylinder engine with 4 valves per cylinder and multipoint or direct fuel injection. The model was developed to replace the obsolete M 112 E28 engine, which was produced since 1998.
Structurally, the V-shaped cylinder block (camber angle 90 degrees) and its two heads are made of aluminum. The cylinder liners are made of silumin. The gas distribution mechanism (GRM) is driven using a double roller chain, the service life of which is 150 thousand km.
Characteristics:
- using a DOHC type gas distribution system (two camshaft in each cylinder head);
- instantaneous change in valve timing of intake and exhaust valves;
- dampers are installed in the intake manifold, which allows you to quickly change its length;
- the presence of a balancing shaft installed in the camber of the cylinder block, which eliminates engine vibrations.
In total, more than 10 modifications of this engine were developed (M272.940 - M272.952). They were installed on Mercedes-Benz cars with indexes 280 and 300.
Maintenance
Maintenance of the M 272 E30 power unit comes down to regular and timely replacement engine oil (every 10,000 km) and coolant. It is also recommended to periodically inspect the engine to identify leaks and promptly eliminate them.
All engines of the M 272 family are critical to fuel quality. Fuel use Low quality leads to failure of the catalysts.
The timing roller chain is replaced after 150,000 km. At the same time, the tensioner and chain guides are also changed.
Malfunctions
The M 272 E30 engine is simple and reliable in operation. Subject to all manufacturer's requirements, it big trouble will not be delivered to the car owner. However, he is also characterized typical faults, the main ones are given in the table.
| FAULT | CAUSE | SOLUTION METHOD |
|---|---|---|
| Lit warning lamp Check Engine(errors 1200 and 1208). | 1. Worn balancer shaft sprockets. | Worn parts must be replaced. |
| 2. The timing chain is stretched. | ||
| Engine oil leak. | The plastic plugs in the cylinder heads are worn out. As a rule, the malfunction appears after 50,000 km. | The plugs need to be replaced. |
| The motor "troits". | The intake manifold flaps have failed. The malfunction appears after a mileage of 100,000 km. | The intake manifold assembly needs to be completely replaced. |
Tuning
You can increase the power of the M 272 E30 engine using various methods:
- Purchase and install on standard piston group compressor. To do this, you will need a kit kit from Kleemann/Lotec, etc. This will increase the engine power to 380 hp. With. The disadvantage of this solution is the very high cost.
- There are also cheaper ways:
- dismantle the catalysts and replace stock firmware to sports (chip tuning). This will increase the power of the power unit by 15...20 hp. With.;
- replace standard ones camshafts to sports ones (phase 268/268, rise 11/11), which will also add power to the engine (about 25 horsepower).
If such an article had been written twenty or thirty years ago, its message would have been clear - power Mercedes units perhaps not the most innovative, but among competitors’ engines there are hardly any more durable ones.
Today, Mercedes engines use a large number of technical innovations designed to reduce the number of harmful emissions and increase productivity while reducing fuel consumption. Unfortunately, this negatively impacted the legendary durability. And if nothing terrible still happens to the engine block and head, then malfunctions of the injection system or supercharger have become something common. Elimination of defects, as a rule, requires large expenses. It is gratifying that the company quickly learns from its mistakes and overcomes them quite quickly.
Gasoline engines 1.6, 1.8, 2.0 M 111 / M 271
Short description:

Compressor or turbocharger.
Mercedes approached the topic of supercharging gasoline engines rather cautiously. The Germans relied on a compressor instead of a turbine to ensure a smoother increase in power without the unpleasant effect of “turbo lag”. The result was presented in 1995 in the form of the M 111 engine with a mechanical compressor driven by a conventional ridge belt. Seven years later it was shown over modern version– M 271.
The most widespread is the 1.8-liter version of the M 271 with a multipoint injection system with varying degrees of boost: from 122 to 192 hp. Some models used a modification with direct fuel injection. It was produced between 2003 and 2005 and developed a power of 170 hp. She can be recognized by her CGI markings.
The desire to reduce capacity led to the creation in 2008 of the 1.6-liter M 271 with a compressor. Its use was limited to the C-Class W204 and the not very successful CLC. The engine did not have direct injection.
The latest version of the 1.8-liter M 271 with direct injection received a turbocharger instead of a compressor. This engine developed from 156 to 204 hp.
Compressor wear.
For a long time, no one took on the task of restoring the compressor, offering only replacement. Fortunately, today mechanics have mastered the technology of its regeneration. The cost of such a service is about 100-120 dollars, including dismantling and installation. The most common compressor malfunction is wear of the rotor bearings, as well as clutch failure.
If the engine makes an annoying whine while the engine is running, then it’s time to intervene. But be careful: worn-out generator bearings make exactly the same sound. You can buy a used compressor from disassembly for about $300, repairing a clutch costs about $500, and absolutely new unit will cost $1,500. Unfortunately, the service life of the compressor is short - just over 100,000 km.
Timing chain jump.
Unfortunately, timing chain wear occurs asymptomatically. It can jump over after 60-80 thousand km. It is a pity that a weak single-row chain is used to drive the timing belt. Luckily, it's not too expensive to replace - about $250. The malfunction only affects M 271 motors.
Oil leakage from the valve timing control.
A typical malfunction of the older generation of M 111 engines. Oil begins to drain from the electromagnets, damaging electrical harness. Effective elimination defect is a labor-intensive task and, worst of all, not always feasible.
Application of engines 1.6-1.8 K/T (M 111, M 271)
These motors were only used in cars Mercedes brand. They were always located longitudinally in front. All units were assembled at only one plant in Germany.

Conclusion
If you decide on a Mercedes with a compressor, then be sure to choose the newer version of the M 271 and be prepared to invest in replacing the timing chain from the very beginning. The advantages of the 1.8 K engine are low fuel consumption. It is better to stay away from older versions of M 111. Alternatively, you can opt for the naturally aspirated 2.0 16V or the later 2.4 V6.
Gas engine V6 2.5-3.5 M 272
Short description.
V-shaped 6-cylinder;
24-valve;
Multipoint injection / direct;
For middle class cars and above, SUVs.
The aluminum V-six, coded M 272, debuted in 2004. It became the successor to the M 112 V6, used since 1998. The main changes are the use of the DOHC system (two camshafts in the head) and 4 valves per cylinder instead of 3. The design uses a number modern solutions: instantaneous change in valve timing of intake and exhaust valves, intake manifold variable length(i.e. dampers are present). In addition, a balancing shaft is used, which eliminates vibrations caused by a large camber angle of the block. As a rule, in V-shaped engines an angle of 60 degrees is used (i.e., a full revolution of the shaft divided by the number of cylinders), and in the M 272 engine it is equal to 90 degrees.
Most units of the M 272 family have multipoint injection into the intake manifold. In 2006, a version with direct fuel injection debuted. Initially the engine with new system got the injection Mercedes CLS, and is currently used in the E-Class W212 with the designation CGI. In 2010, the successor to the M 276 was introduced, however, motors of the M 272 series are still produced today.
Operation and typical malfunctions
The M 272 engine has only one characteristic malfunction. But its elimination is expensive, and the consequences are quite serious. This makes it quite difficult to recommend the Mercedes V-6.
Worn balance shaft teeth.
The defect has become so widespread that in the USA owners faulty cars filed a lawsuit against the company in the United States, demanding free repair broken M 272 engines. Wear on the balance shaft gear teeth accelerates chain wear and can cause it to skip. In addition, as a result of improper operation of the gas distribution system, dangerous composition mixture in the cylinders, which leads to the destruction of the catalyst. The malfunction affects all engines with serial number up to 2729…30 468993 inclusive. The parts for the repair are not too expensive (about $250), but the procedure requires removing the engine, which will cost about $700-$1,000.

Conclusion
Just one, really serious defect casts a shadow on the reputation of the entire family of M 272 engines. Engines in which the defect with the balancing shaft has been eliminated are worthy of recommendations. The 5-liter V8 is famous for much greater reliability, though average consumption fuel is 17 l/100 km.
Diesel engine 200-220 CDI-OM 611
Short description.
4-cylinder;
16-valve;
Common Rail injection system;
Turbocharger;
For middle class cars and above, vans.
In 1997, major changes occurred in the history of Mercedes diesel engines: for the first time, a common rail direct injection engine was used. It was used in the first generation Mercedes C-Class with a station wagon body. At the same time, the designation CDI appeared, which is still used today.
The engine was marked OM 611. It has 4 cylinders and a displacement of 2.2 liters. The first samples developed 125 hp. and 300 Nm of torque. Compared to its predecessor OM 604, the new unit received an increase in power by 30%, torque by 100%, and fuel consumption dropped by 10%. The injection system operates at maximum pressure 1350 bar. Initially, the engines were equipped with a turbocharger with constant geometry, and since 1999, a supercharger with adjustable position turbine blades. The displacement was also slightly reduced from 2151 to 2148 cm3. The gas distribution system is driven by a chain, there are two shafts in the head, and there are four valves for each cylinder.
The OM 611 engine family has several different modifications. In passenger cars (C and E-Class) a unit labeled 200 CDI (102-115 hp) and 220 CDI (124-143 hp) was used. In addition, there are variations with a power of 82 and 102 hp. for Vito, Viano and Sprinter vans, 122 hp – for Vito and Viano, and 129 hp. for Sprinter.
In 2002, with the debut of the E-Class W211 series, the new generation 4-cylinder engine OM 646 and its derivatives, the 2.7-liter OM 647 and 3.2-liter OM 648, were introduced. Despite the similar design, about 80% of the components new.
270/320 CDI (OM 612 /OM 613)
The next direction of development of the OM 611 engine family was an increase in the number of cylinders. The 5-cylinder unit was designated OM 612, and the 6-cylinder unit was designated OM 613. The first, labeled 270 CDI, developed from 156 to 170 hp, and the second, 320 CDI 197 hp. Mention should also be made of the 3-liter version with 612 ohms and 231 hp, designed for the C 30 CDI AMG.
Operation and typical malfunctions
Mercedes diesel engines of the previous generation were famous for their incredible endurance. Due to the more complex design, sometimes problems arose with the OM 611. Simply, a larger number of elements had a greater chance of breaking. Fortunately, serious malfunctions didn't happen too often. The cylinder-piston group has high strength. The turbine and dual-mass flywheel typically last several hundred thousand kilometers. It should be borne in mind that the mileage of a car in advertisements for sale coincides with the real one only in exceptional cases. When choosing a car with CDI, you must be guided by the assessment technical condition specific instance.
Difficulty starting.
Typically associated with pump wear high pressure, less often with a malfunction of the injection system - nozzles.
Intake manifold.
In many versions of the engine, dampers were installed in the intake system, the closure of which increased the turbulence of the air entering the cylinders, which improved the quality of its mixing with fuel. Malfunctions of this element lead to a noticeable decrease in engine power and slow growth of revolutions.
Thermostat.
CDI engines heat up quite slowly. But if even after several tens of kilometers the engine still does not reach the desired temperature, then you will have to replace the thermostat.
Application of OM 611
4-cylinder engines were used in class C and E passenger cars, and in minibuses. 5 and 6 cylinders in larger models.
Mercedes C-Class W202: 09.1997-05.2000;
Mercedes C-Class W203: 05.2000-02.2007;
Mercedes E-Class W210: 06.1998-03.2002;
Mercedes V-Class: 03.1999-07.2003;
Mercedes Sprinter: 04.2000-05.2006.
Conclusion
Very good engine for its time - an inexpensive injection system and a durable cylinder-piston group.
In the case of the E-class, instead of the 220 CDI version, you can consider a model with a 270 CDI.
Diesel engine 200-250 CDI-OM 651
Short description.
4-cylinder;
16-valve;
Common Rail;
Turbo or biturbo supercharging.
In 2008, Mercedes introduced a new generation of turbodiesel with the designation OM 651. Initially, the unit had a displacement of 2.2 liters, and since 2011, a 1.8-liter unit has been added to the family. Both diesel engines have the same cylinder diameter, but the smaller one has a shorter piston stroke - 83 mm instead of 99 mm. The compression ratio in both versions is 16.2:1.
The engine debuted in its in better shape– 204 hp It was installed on C-Class cars 250 CDI. The power unit had a twin turbocharger and Delphi piezoelectric injectors. The same solution (biturbo and piezoelectric injectors) was used a little later in the weaker 170-horsepower version of the 220 CDI. And if there were no special problems with supercharging, then the injectors caused a lot of suffering. They were so serious that in 2011 the 220 CDI modification, and since 2012 the 250 CDI received conventional electromagnetic injectors.
Weaker versions (up to 200 CDI 143 hp) used less troublesome electromagnetic injectors from the very beginning. In addition, these engines had a single variable geometry turbocharger.
OM 651 replaced a wide range of older generation engines - 4, 5 and 6 cylinders, installed longitudinally and transversely, ranging from compacts to vans.
Operation and typical malfunctions
Problems with piezo injectors cast a shadow on the reputation of OM 651. The scale of the vice turned out to be enormous. To eliminate defects during warranty period, the current engine production had to be stopped. It must be admitted that Mercedes approached the issue of eliminating the problem in good faith. Motors with conventional injectors did not create such problems.
Piezoelectric injectors.
This standard fault first years of production. The engine went into overdrive while driving. emergency mode. There have been cases sudden stop motor. Currently, the scale of the problem is small.
Valve train chain.
As the mileage increases, more and more facts about problems with the timing chain are recorded. Replacement is troublesome - the chain is located at the rear of the engine.
Pump leaking.
Another problem that is gaining momentum with increasing mileage and age of cars.
Application of OM 651
The OM 651 engine has found wide application, ranging from compact models to limousines, sports cars and even vans.

Epilogue
Legendary Mercedes engines in pursuit of power, low consumption fuel and environmental friendliness have lost their former reliability. The block itself with cylinder-piston group designed for at least 500,000 km, but auxiliary equipment It fails much earlier, and repairs are very expensive.
Mercedes cars are the embodiment of quality and style, because German manufacturer produces reliable cars that are adapted to any road. The contract Mercedes engine is designed for long mileage and is excellent for replacing the “original” engine.
A little about contract auto engines
Boo Mercedes-Benz engine - This is a line of 4, 5, 6-cylinder units. They have a row or V-shaped configuration. For the most powerful cars units of the V8 and V12 series were produced. There are supercharged engines equipped with twin turbo, compressor and turbine. Sports cars AMG series are equipped with V8/V12 engines. Besides power motors The production of diesel engines also continues. Such engines come in various configurations, power and volume.
You can buy a contract Mercedes engine from the Auto Parts company. It is enough to pick suitable model and place an order.
Typical Mercedes engine breakdowns
The need to replace a used Mercedes engine arises as a result of the most common breakdowns:
- unusual motor noise during operation indicates normal wear and tear compressor. The same sound indicates a generator bearing failure;
- stretching or jumping of the timing chain - such a breakdown is asymptomatic. Occurs when high mileage 60–80 thousand km;
- a leak motor oils. As a result of runoff motor fluid Damage to the harness occurs from the electromagnets;
- damage to the balancing shaft. Its teeth wear out over time, reducing the period of use of the motor. A possible violation of gas distribution provokes the formation of a dangerous mixture, leading to the destruction of the catalyst;
- difficulty starting. The internal combustion engine may refuse to start due to damaged injectors and a worn high-pressure pump; in this case, you should think about replacing it with a used Mercedes-Benz engine;
- interruptions in the operation of the exhaust manifold lead to a decrease in power;
- Thermostat malfunctions lead to the unit stopping heating even after long operation.
The occurrence of one of these problems leads to the fact that the car engine needs to be changed. The price of a used Mercedes engine depends on specific model and its power.

Mercedes cars in the W124 body were produced in Germany from 1984 to 1996. At its debut at the Seville Motor Show, the W124 was presented to the general public with seven types various engines. These are models: 200, 230E, 260E, 300E, 200D, 250D, 300D. The presence of the letter “E” after the numbers in the model name gasoline car at that time it meant that the engine was injection. In 1993, the entire family of Mercedes in this body began to be called the E-Class and the letter moved to the beginning of the model name. Engines with a carburetor were no longer produced, and there was no longer a need to denote the difference by adding additions to the name. U diesel options The “D” marking has disappeared from the model. It was replaced by an addition in the form of DIESEL, or TURBODIESEL.
In 1987, the 300D TURBO was additionally added to the engine line, and a year later the 200E and 250D TURBO.
In 1989, the entire series of diesel engines was modified to meet the requirements of the Diesel-89 program. The pre-chambers were updated in the engine design, and a new fuel pump. As a result, exhaust smoke decreased by 40%.
In 1990, a 3.2 liter engine became available in all model body styles. Gas engine M104. In the same year, the 500E model with a 5-liter engine and 326 hp was released. (Top)
In 1992, the range of gasoline engines was greatly updated. The design now has 4 valves per cylinder, while a new one was installed instead of the old injectors. electronic system fuel injection. In the end, everyone gasoline units Power has increased, torque has increased, and harmful emissions have decreased. Then it became available a new version 400E, equipped with 4.2 liter engine(gearbox, of course, automatic). At the end of 1992, they began to update and diesel engines. Engines with five and six cylinders received 4 valves per cylinder. Four-cylinder engines and turbocharged diesels still had two. The update improved engine power and torque, reduced fuel consumption and emission levels. Motor diesel versions, like gasoline ones, began to be equipped with a standard catalyst.
Let's take a closer look at each engine model used on the W124 family.
Gasoline
M102.
Appeared in 1980 and was produced until 1993, until it was replaced by the M111. It was a four-cylinder gasoline engine.
It was produced in both carburetor and injection versions.

Sores: problems include frequent blockages in the injectors and, as a result, instability in the engine. It is advisable to check the injectors regularly and replace them if necessary. In such engines, the crankshaft seals and the front cover gasket often leak. It is best to change valve stem seals every 100 thousand km. mileage, otherwise oil consumption will increase. These motors have quite weak chain Timing belt and drive sprockets. As a rule, they wear out within 100-150 thousand km. and they need to be repaired.

The history of the concern begins with the history of two independent companies that ushered in the era of global automobile manufacturing. In 1883, Karl Benz founded Benz& Co, the result of which was the world's first mass-produced passenger car, which appeared on the market in 1894. In 1890, Gottlieb Daimler founded the Daimler-Motoren-Gesellschaft society, in whose workshops the first car called “Mercedes” (named after the daughter of one of the company’s co-owners) appeared in 1901. In 1926, competing companies merged to form Daimler-Benz AG, and the car model they produced was called Mercedes-Benz.
The brand's logo is a three-rayed star, symbolizing the three elements - air, water and earth. In addition to the production of cars, trucks and special vehicles the company produced high-power engines for motor cars, boats, ships and aircraft. The name of the Daimler-Benz concern was created by outstanding engineers Ferdinand Porsche, Fritz Nallinger and Hans Nibel. By the 1930s, the company had established itself as a designer and manufacturer of luxury cars.
All Mercedes Models:
The history of Mercedes - Benz includes many cars that have become iconic: the world's first production passenger car with diesel engine Mercedes - Benz 260D, elite “770 Grosser”, Mercedes W126, class S generation, indestructible W190, W123, W124, classes C and E, which set new standards for quality and reliability, the famous super-luxury 300s and 600s. Models are produced with reliable and high-tech engines of various modifications, high-quality suspension, standard design interior, body high degree passive safety, new security systems EPS, ASD, 4MATIC. In 1998, Daimler-Benz AG and Chrysler Corporation merged. The result was the most gigantic automobile corporation in the world - Daimler Chrysler AG. Having initially relied on elitism and prestige, Mercedes was nevertheless able to become a truly popular brand. While producing luxury cars, the manufacturer did not forget ordinary consumers: in model range There were always more affordable models. And in any configuration, Mercedes remained a super-reliable (until recently;), prestigious, comfortable and convenient car.
