Team AngarMotorov
With the launch of the new, slightly improved 3-Series, Bayerische Motoren Werke has brought some confusion to their ranks. For example, in Europe, the new 330i model will replace the previous 328i, but this will happen purely nominally, since the engine will not change its volume and everything will also be represented by 2.0 liters.
I remember there were a few other times when everything was different. Everything was much simpler and more intuitive. The 328i had a 2.8 liter engine under the hood, while the 330i, of course, had a 3.0 liter engine under the hood. And so on and so forth, at face value.
According to the logic of things, such a "forgery" is not accidental and is partly justified. The volumes of motors, of course, are becoming more modest, but here is the power ..., on the contrary, the power is growing, and at a very fast pace. Before you know it, the new model beats last year's by a good couple of dozen horsepower. Over decades of continuous progress, engines that were considered small in the early 90s, 1.6, 1.8 and even 2.0 liter engines now produce more power than that developed by 2.5, 3.0, and even 4.0 liter units at the end of the 20th century.
So it turns out that if we count in terms of horsepower under the hood, then some BMW with a “modest” and nothing remarkable 2.0-liter engine can easily make a 4.0-liter monster of the past century in terms of peak power. About others important parameters as an output to peak torque from 1.800-2.000 rpm or efficiency during normal operation, we are generally silent.
And in order to make it psychologically more comfortable for buyers and not to scare away customers with nameplates 1.6-1.8 on the trunk lid, like other leading automakers are experimenting with the names of their models, do not write horsepower on board, really?
To understand the full depth of changes in the range of BMW engines, we will try to find out which are the Top 5 BMW engines have been fitted to 3-Series vehicles for many years. Including "M" models.
5 - BMW M42 B18, 1.8 liter in-line four-cylinder, 138 hp With. (E30, E36)
Fifth place, took the well-known 1.8 liter BMW unit. Hush, hush, don't drive the horses! We understand that it may not be from Bavaria, but listen to us.
First, where was it used? In lightweight e30 and e36 bodies, often in 318iS models. Let's face it, it's not the best. best bmw in terms of dynamics and drive (it so happened that BMW owners give this notorious “drive” to everyone as one), but the 1.8-liter engine still fulfilled its mission. Behind acceptable price you bought a near-sport car with a wide range of refinement options and dynamics in the stock state of just over 10 seconds. For the late 80s, the first half of the 90s it was for real valuable breakthrough. The Bavarians brought the feeling of a sports car to the masses. Moreover, everyone could purchase models with this engine without overpayments.
Why didn't the Germans take the success further and offer a model for expansion to other continents? The fact was that in South Africa in those years the idea prevailed that cool car should be compact and lightweight and carry in your engine compartment largest of available engines. Needless to say, the coupe still had that temper, not everyone was subject to all the power of this rare nugget.
3 - M47, 2.0 liter, gasoline in-line four-cylinder, 136 hp With. (E46)
With this engine, BMW has shown that diesel can be fun. In fact, the 320d, powered by a 134 horsepower 16-valve engine, was faster than a 2.0-liter 6-cylinder petrol model 320i, which had 148 hp. Both cars hit 100 km/h in 9.9 seconds, after which the torque kicked in and the 320d easily passed its less nimble counterpart.
Shortly after entering production, the M47-based 3-Series set the standard for affordable, reliable and economical sports sedan. Sounds paradoxical? Perhaps, however, this explains why the 320d models are so successful to this day.
2 - S54, 3.2, straight-six, 338 hp (E46)
Okay, enough talking about 1.8 liter engines and diesel engines, it's time to withdraw heavy artillery. This 3.2-liter monster, which was on the E46 M3, is undoubtedly one of the best engines BMW of ever made. It was based on the M54 DOHC inline six-cylinder engine, used an aluminum block and a solid aluminum cylinder head.
It had individual throttle valves for each cylinder, lighter pistons, larger intake valves, VANOS high pressure variable valve timing system for variable valve timing, the list of advanced technical solutions is not complete, it can be continued for a long time ...
The S54 is not far from BMW racing engines and was the last naturally aspirated engine to be installed on the M3. The power was enough to accelerate the M3 from 0 to 100 km / h in 5.1 seconds, with maximum speed limited at around 250 km / h.
1 - S65, 4.0 liters, 420 hp (E90/92/93)
What is the easiest way to develop a V8 engine? Well, in the case of BMW, you need to get rid of two cylinders from the S85 V10 engine. Yes, the V8 version found on the 4th gen M3 is a derivative of the monstrous F1-inspired road-going V10 that was in production line BMW.
IN this review showcasing BMW petrol and diesel engines that have been in use for the past 15 years. Because of the huge range power units As a Bavarian company, we cannot cover all engines and their variants. Nevertheless, we will dwell in detail on the most famous and popular motors.
BMW is one of the world's leading manufacturers, offering the most modern and advanced powertrains on the market. Therefore, you need to be prepared for large bills for maintenance and repairs. You don’t have to look far for examples - for many owners it comes as a surprise that the need to periodically replace the timing chain drive used in all modern BMW engines comes as a surprise. The chain and tensioner, as a rule, take care of about 200-300 thousand km. This creates noise, and the engine runs unevenly. To replace the timing chain, it is necessary to prepare about 20-30 thousand rubles. In the case of older instances, difficulties arise when trying to conduct overhaul– the materials used for the manufacture of cylinder liners do not allow their restoration.
What expenses await you after buying a used BMW depends on the condition of the car and the version of the engine under the hood. Our review will certainly help to make right choice.
Engine marking
German concern BMW has been one of the leaders in production for many years automotive technology, parts and assemblies. BMW engines are no exception. The line of power units of this company is quite large. To identify a specific series of engines, letters are used:
- M - for standard serial motors;
- S - for sports engines motorsport;
- N - for modern engines new generation;
- P - for prototypes.
It is worth noting that the BMW engines used in the second generation X5 model are classified N, which indicates the use of innovation and latest developments. Modern models The X5 is equipped with several types of supercharged gasoline and diesel engines.
Engine M21 2.5 liters (diesel) 82-91 (E28, E30)
M21 - 6-cylinder diesel engine - was the first diesel in the history of BMW. Production began in 1982 to equip the 524td in the newly introduced E28 body. M21 was equipped with a turbocharger, which allowed diesel version save the image dynamic machine, common to all BMW models. With the release of the new E30 3 Series bodywork, the M21 has another use for the 324td.
In 1985, an attempt was made to produce an economical non-turbocharged version. But the leisurely 524d and 324d didn't sit well with buyers. The very next year, the production of naturally aspirated diesel engines was discontinued and never resumed.
M30 engine 2.5, 2.8, 3.0, 3.2, 3.5 liters
BMW concern poached Bernard Oswald from Ford to develop the second generation of six-cylinder engines in the mid-sixties. The first were six-cylinder engines with seven crankshaft bearings. They were used in the new E3 series sedans in 1968. The successful M10 formula was reapplied - cast iron block, aluminum head with chain drive camshaft. After 1972, the development took place under the control of Gustav Ederer and it was then that the first model with 4 valves appeared - M88
The M30 engine is a large 6-cylinder in-line engine that has modifications of 2.5, 2.8, 3.0, 3.2 and 3.5 liters of displacement. It can be found on the 5 Series (E12, E28 and E34), 6 Series (E24) and 7 Series (E23 and E32), as well as the famous BMW M1.
The engine turned out to be very successful, both in design and in survivability. Of course, partly the survivability of the engine was ensured by its big power. In view of the fact that more powerful engines and load less.
Only the M30B35 modification with a cylinder diameter of 93.4 mm was unsuccessful - it turned out to be too energy loaded. But do not confuse it with the M30B34, which was installed on almost all 3.5 liter cars.
M30 is an engine for quiet ride, he has too heavy a piston and too big moves piston, which prevent it from spinning quickly and create heavy loads on bearings (liners).
Also, due to the high mass piston system the engine is very demanding on oil if fed mineral oil and at the same time constantly keep it in the rev range of 4-6 thousand, after a few thousand you will have to grind the crankshaft. Only synthetic oil should be poured into this engine, and if you like to turn it, then on volumes of more than 2.8 liters, installation is required oil cooler.
On the other hand, the advantages of balancing the inline six and high power on low revs more than compensate for these shortcomings.
Also M30 - was the second and latest engine on which turbocharging was serially installed - turbocharged modifications of the M30 were used only in the 745i models in the E23 body. In fact, their volume was 3.2 and 3.4 liters, depending on the modification. But both options were marked M102. The power is the same - 252 hp. The main difference is the ignition and power system.
The engine was installed on cars of the third, fifth, sixth and seventh series.
3rd series:
E30 - 333i - 3.2. liters, with Motronic injection system. Supplied only in the UAE.
5th series:
E12 - 525 - 2.5 liters with carburetor, 528 - 2.8 liters. with carburetor and injector, 535i - 3.5 liters, only with an injector.
E28 - models 525i, 528i, and since 85 535i and M535i. Starting with the E28 body, only injection modifications were installed.
E34 - 530i - 3 l., 535i - 3.5 l. Also, only the injector with the Motronic injection system and with the crankshaft position sensor located on the crankshaft damper, and not on the gearbox.
6th series:
E24 - 628CS with carburetor and injection (628CSi), 633CSi, 635CSi - injector only. 
7th series:
E23 - 728 injector / carburetor, 730 carburetor, 732i / 733i, 735i, 745i - a turbocharged version of the engine was installed on the 745i model.
E32 - 730i, 735i - 3.0 and 3.5 liters, respectively.
BMW M47 - inline 4-cylinder diesel engine
First released in 1998, the M47D20 delivered 100 kW (136 hp) of power and 280 Nm (207 ft lb) of torque in the 320d/520d variant, and 85 kW (114 hp) with 265 Nm (195 ft lb) ) performed by 318d. All M47 engines have one valve and one swirl injector per cylinder, each of which can increase performance in various conditions. An indirect block was installed on the M47diesel fuel injection with an engine capacity of 1951 cc.
Initially, thermostats were installed on all BMW engines of that time, which, when worn out, caused additional cooling engine, which worsened the performance of the engine in terms of fuel consumption. Subsequently, the BMW plant changed fuel system engine to a high-pressure single-row system.
The turbocharged BMW M47 diesel engine uses a Garrett turbocharger with variable geometry(VGT), also known as variable vane turbocharger. These early VGTs used until September 2003 vacuum system to control the drive, which in turn controls the movement of the blade. Over time, drive vacuum tubes are prone to breakage, which can affect the operation of the entire turbo. Later turbochargers (after September 2003) are electronically actuated and failure can result in costly replacement of both the compressor and the entire drive. Fortunately, in some cases the actuator can be repaired separately without replacing the turbocharger.
To help keep the turbocharger and engine running perfect condition, are obligatory regular replacements synthetic oil and filters after a run of 7000–8000 km. Also needed regular check plastic parts oil separator or replace them every 12-18 months in order to avoid clogging and an increase in internal pressure.
If you have a turbocharger failure on this engine, and the scan cannot reveal specific error codes, then you can check all connections vacuum tube and the state of the vacuum tank itself. To do this, simply disconnect the vacuum hose.
The whistle of the engine turbine is another unpleasant sign inherent in this engine. Some turbos whistle more than others and this may simply be a sign of general engine wear. If the sound resembles a police siren, then we advise you to check the gap on the turbine shaft as soon as possible.
To gain access to the compressor shaft while the engine is warm, remove the air duct and pinch the shaft between your thumb and forefinger. In this way, you check how much the bearings "float", both from side to side (radial clearance) and along the axis (axial play). The axial clearance is typically between 0.025-0.1 mm and can hardly be felt, the radial misalignment is typically between 0.3-0.6 mm. For more accurate measurements, you will need a dial gauge. But if the "floating" movements seem excessive, then an immediate repair is most likely required. 
Unusually high oil consumption combined with blue smoke from the exhaust pipe can be a symptom of worn seals. In very rare cases, the engine may run on its own oil, which will cause plumes of smoke. If this happens, turning off the ignition may be pointless, since it burns engine oil which can lead to engine seizure. Try braking the car with the clutch without taking your foot off the brake.
The M47 motor for its time was the best in terms of technical characteristics in its class. However, it has a number of features that entail an increase in maintenance costs. However, compared to its successor N47, it is less problematic and overall a better engine. It can be argued that this is a very successful motor, although it is not necessary to rely on the low cost of operation.
BMW engine: diesel unit
The small D in the BMW model name means significantly great results. Every BMW diesel engine, whether four, six or eight cylinders, guarantees refined power and superior fuel efficiency. Improved turbochargers, modified turbine geometry and system direct injection allowed to take a fresh look at the diesel engine.
The price of such innovations: 306 liters. With. power at a flow rate of not more than 7.5 liters per 100 km. Acceleration to hundreds is only 6.6 seconds. No matter what engine is installed in the BMW X5, there is one thing you can always be sure of - maximum comfort driving combined with maximum performance.
TOP 5 BEST BMW ENGINES
TOP 5 WORST BMW ENGINES
BMW AG - famous and very popular German manufacturer cars from the city of Munich, Bavaria. Together with Audi and Mercedes-Benz, it is part of the so-called big German troika and all cars produced by it belong to premium class. BMW company also owns Mini and Rolls-Royce.
BMW engines, for the most part, are very reliable, quite technologically advanced, durable and have repeatedly received the title of "Engine of the Year". The range of power units is very wide: these are turbocharged three-cylinder B38, four-cylinder (from M10 / M40 and ending with N20 / B48), legendary inline sixes BMW (from M20/M50 and older to N54/N55). Together with BMW engines of the above configurations, for the top models of the company, even more large motors: V8 (from M60 to N63) and V12 for the flagship series. Along with the usual urban versions, the branch of BMW M GmbH has produced and continues to produce sports modifications based on standard power plants. Since 2005, the production and own M-engines: S85 with V10 configuration and later its simplified version V8 S65. Parallel to gasoline engines diesel ones were also produced. Family diesel engines BMW is not so wide: three-cylinder B37, M41 / M47 / N47 / B47 fours, M21 / M51 / M57 / N57 sixes and a large V8 M67.
BMW cars have earned special love from residents of the CIS countries, so it will not be difficult for a buyer to find a model with a BMW engine of any family, version and modification. And to understand all this diversity, it will not be superfluous to use the reviews from Wikimotors.
Below you will find reviews and descriptions of BMW gasoline and diesel engines, old and new, naturally aspirated and turbocharged, conventional and sports M series, their technical specifications, where they are produced, which oil is recommended to be poured into a BMW engine. In addition, the main diseases are described (knocking, oil consumption, power reduction, etc.), shortcomings and problems, as well as repair of BMW engines (gasoline and diesel), tuning, the right approach to increase power and much more.
After reading all about BMW engines on WikiMotors, you will easily understand which Bavarian model to choose or which BMW contract engine to buy.

When it comes to BMW parts, many immediately have positive associations on this score, and BMW engines are no exception. But, as shown by many years of experience in the field of working with cars of this brand, directly with engines, the opinions of many that these units have a high degree reliability, are caused more by public opinion than by reality. That is why it is worth considering some of the most popular models separately, in order to still understand their true origin, quality and performance properties.
BMW M10, M20, M30, M40, M50 engines
These motors were the first models developed by the famous concern. The crankcase ventilation system is completely primitive and works due to the pressure difference. CPGs have minimal wear at 300-400 thousand km. the path traveled. And here valve stem seals begin to lose their elasticity after 200 thousand km. run. This suggests that they are likely to have problems. It is also worth noting that the requirements for oil are low for the simple reason that engines were created precisely at a time when the synthetic oil market was just gaining momentum, which means that it was not possible to look for something better, it was necessary to take what is. This is a generation of motors that was repaired without any problems in their own garage.
BMW M10 engine
- it is single shaft carburetor motor which has an ignition distributor. Thanks to the constant release updated versions and modifications, the motor was installed on Bavarian cars for almost 30 years. You can meet this motor in many cars, however, in Russia they are a real rarity.
BMW M40 engine
- This is an improved motor of the previous brand with hydraulic lifters and a belt drive. Not common, but quite reliable model.
BMW M20 engine
- This is the first six-cylinder belt-driven. This model took an intermediate place between m10 and m30. The thing is that the four cylinders of the M10 model did not make it possible to increase the engine capacity by more than 2 liters and achieve full power, so adding two more cylinders helped to cope with the task. In our country, this motor was popular in a configuration with a body number 34, by the way, it has proven itself on the positive side.
BMW engine M30
- the main six-cylinder unit of the first generation. The set of characteristics of this motor is classic: an ignition distributor and one camshaft. BMW Model M30 had many modifications, including for sports cars M-Sport series. It became the basis for the popular S38 sports engine. In our country, it took root in cars with the 34th and 32nd bodies and became the leader among the M series.
It should be noted that all these engines had one common feature- they all had a low compression ratio, approximately 9:1 and 8:1. This allowed the use of fuel with any octane rating, due to reduced sensitivity, and produce factory turbocharged engines without any special modifications.
BMW M50 engine
If you believe the statistics, then this motor became the last potential "millionaire" of the first wave. This model has a number of significant differences that allow it to be considered apart from other first-generation engines.
This engine gave the much-needed 4 valves per cylinder, establishing a fashion for the "explosive" nature of BMW engines that has survived to this day. Some new items appeared in this motor, namely more modern candles and ignition coils. It was this model that set the standard, which subsequently was practically not violated - "1 Nm per 10 cubic centimeters of cylinder volume", which was not possible to achieve in atmospheric engines the past generation. True, after that there was a need to significantly change the compression ratio from 10 to 11: 1, it was possible to repeat this only in 2005, in the BMW N52 engine. This unit moves perfectly on 95 fuel, but for a 2-liter modification, even such an OC may not be enough.
Knock sensors help to compensate for this shortcoming, although adjusting the ignition timing only helps to mitigate the consequences of using the wrong fuel: unfortunately, the car does not drive better from their presence. The BMW M50 motor is the last copy that used the “indestructible” tandem - “aluminum cylinder head - cast iron block”.
The unit, which appeared in 1989, according to the combination of consumer and specifications, probably became the best in the history of the BMW concern.
BMW M52 engine
Considering this engine, I immediately want to say that its name sounds a little wrong, because in fact it is an improved series. When the unit received an update in 1992, it entered the markets with the M50TU index, and only then, over time, they decided to transfer it to a new generation. After all, this is the first engine that received a valve timing control mechanism. intake shaft, known as VANOS.
The addition of 2 valves resulted in a doubling of the flow area, which negatively affected the filling of the cylinders at low speeds. It also caused a curvature of the torque characteristic, degrading the ride quality. low speeds. BMW system VANOS was supposed to smooth out the knots of the engine by stretching the torque characteristic. Power was increased, and this was done absolutely standardly - minders added 300 cubes - a 2.8 liter engine turned out. By the way, according to some reports, it became known that non-standard engines of 2.8 and 2.3 liters were created, as it met the German tax standards of that time.
The BMW M52 engine block became aluminum, and the cylinders received a high-strength nickel coating. Manufacturers also took care of the environmental friendliness of their products and paid due attention to it. M52 became the first engine with a ventilation system crankcase gases, for this, a valve was used that opens “on demand” and has atmospheric pressure. They also raised the thermostat opening temperature, which increased to 88-92 degrees, and higher than the performance of the first generation engines.
The resource of this model has decreased by approximately two: defects of caps and CPG climb out from 200-250 thousand km, with the expected engine resource of 450-500 thousand km. The operating mode can take away or add 100 thousand km to this figure. Oil consumption, even with a partial loss of mobility of the rings, may be completely absent or remain extremely small. We can say that the BMW M52 engine has become the last potential long-liver millionaire, with good care.
Features of operation are often associated with the occurrence of problems with not yet fully electrical equipment and expensive consumables - the drive cables stretch and lose their elasticity throttle valve, there are problems with the anti-skid system, expensive flow meters, ABS blocks and expensive titanium oxygen level sensors deteriorate. However, with proper care, you can count on an impressive engine life. Basically, the E39 and E36 models were equipped with this engine.
Engine BMW M54, M52TU
These motors are characterized by improved elasticity of the torque characteristic. The biggest and significant difference between the new and the old unit lies in the thermostat, which has an opening point of 97 degrees - the operating mode is shifted to partial loads, which made it possible to provide complete combustion fuel. This favorably affected the operation of the car in urban mode.
It was the BMW concern that discovered this system and still remains faithful to it, and no one has managed to intercept it until 2012 and does not raise the degree of oil far beyond 100 degrees. If we talk about urban use, then the oil begins to oxidize twice as fast, and this leads to the fact that maximum mileage decreases and becomes equal to 180 thousand km. In addition, this particular engine is very picky about the choice of fuel, and if you neglect this point, then in the future you can pay dearly.
The designers also took care to raise the power characteristics, and that is why VANOS began to control the exhaust shaft as well, and the DISA damper appeared on the intake. Only now the design is now plastic, which means it is not durable. The M54B30 engine has a wide rev range, but it no longer has the bright M50 characteristic. Incidentally, it should be noted important point that the gas pedal becomes electronic and very sensitive. And in a block of aluminum for the last time use cast iron sleeves, but this is a turning point in the history of the concern. The motor, despite all its small flaws becomes very popular in our country, and is especially common in cars with a body of E53, E46 and E39.
All M series units are characterized by the formation of slag on the oil filler neck, which allows you to visually determine the quality of the product used. The layer must be dry and thin, then you can immediately understand that the engine is alive.
This is a new generation that appeared in 2005. The unit is designed hot and frisky, as engine compartment received new layout. All systems that were previously used have been improved. Oxygen sensors have become broadband, the manifold has become two-stage, the reliability of the ventilation valve has increased, and much more.
The block is made, as before, from an aluminum alloy, but cast-iron sleeves are no longer used, instead of them a special oil-retaining coating. The air supply system has also changed.
It is worth saying that among the owners of cars of this concern, the expression “hit the valvetronic”, which means the amount of 1000 euros, has become popular. True, there is a little consolation, now the fuel economy is 12%. Also, all N-motors have a problem associated with the control unit.
Cars that are operated in the city sometimes have engine problems associated with sticking rings, which occurs approximately 50-60 thousand km. run. A little later, a problem with caps may begin to arise, and when the mileage is 100 thousand km., Both problems require repair. After 100 thousand km, the catalyst is clogged. In general, if the mileage goes beyond 180 thousand km, you should not give preference to such a unit. And if in fact, then problems can arise much earlier, approximately 100-120 thousand km. The engine is found quite often on cars of the first, third and fifth series.
By the way, it should be said that the rumors about the modernization of the motor: the installation of a new skirt and rings were not confirmed, the resources of this model remained the same.
BMW N53/N54/N55 engines
N-series engines began to strive for environmental friendliness. But many fans of the brand were disappointed in the result. This suggests that not all innovations are successful.
With the advent of the N53 engine, it became clear that BMW diesel engines would soon take their well-deserved place among their gasoline counterparts. New line was created not as economical units, but as aimed at preserving environment. Buyers got the opportunity to purchase engines with new nozzles, with high pressure and with all the disadvantages diesel engine. also in new model Valvetronic didn't hit, it just didn't fit.
Valvetronic was also not included in the N54 series. But this model slightly changed the engine range, because turbines began to be used again.
But Valvetronic was returned to the N55 series, but the turbine system was removed. Yes, you can start to rejoice at this news. And it is this engine that is the most important and the most "diesel" among the entire series of this series.
The concern decided not to immediately promote the motor on the world market. Possibly due to coking in the injectors. But it is worth noting that at the same time, BMW coke nozzles are very different from competitors' products that use an open hole.
Due to different design valve cover, the primary self-diagnosis now has nothing to do with the M series motors. To understand that the oil needs to be replaced, you can carefully look at the petals of the cover and consider the presence of plaque there red-brown, at first it can be removed, but then this will not be enough. In the second stage of the "dying" of the oil, brown sand will appear on the lid. But the third and fourth stages will be visible quite strongly, since brown sand will be over the entire surface of the lid, and under it you can see a dirty-colored jelly.
In general, to summarize, it becomes clear that to purchase an N55 series motor, which is really good and for a long time will serve, it is almost impossible. And if the car is more than 5 years old, then you should not even try.
What car do you drive ???
