Mercedes-Benz OM654 engine
Content
4-cylinder diesel power unit manufactured by Mercedes since 2016. The first model equipped with this engine was the E220 D. The engine was launched in the city of Stuttgart. It replaced the outdated OM651.
Overview of the OM654 engine
In the US, the engine was first presented at the Detroit Auto Show. The first modification of the engine was the DE20 LA version, equipped with Common Rail direct injection. The pressure of this type of injector provides up to 2000 bar, which in itself gives good performance. The working volume of this modification is 1950 cm3, and the power varies between 147-227 liters. With.
The engine body and cylinder head are made of aluminum alloy, the pistons are made of durable steel. The cylinders are coated with a special Nanoslide material that provides protection against friction. The motor is cooled by a turbine with a modified section at the inlet.
The engine has an option called exhaust recirculation, otherwise the EGR valve. It provides multiple cycles of exhaust gases. The diesel catalyst is responsible for lowering the CO2 level. Without it, the amount of nitrogen and sulfur released into the atmosphere would be much higher. In addition to these elements, a diesel filter and SCR are also present in the exhaust system. Thus, the amount of emissions is 112-102 g / km, which fully meets the Euro 6 standards.
The OM654 engine consumes about 4 liters of fuel per 100 kilometers. The car with it accelerates to a hundred in 7,3 seconds.

Overview of the OM656 engine
6-cylinder power unit from the new series, with a working volume of 2927 cm3. It was first introduced on the restyled W222 S-Class. Its power is 313 liters. s., and a torque of 650 Nm. Like the younger four-cylinder analogy, the engine has the same aluminum body and steel pistons coated with Nanoslide - an alloy of iron and carbon. Thus, the modular platform for the 4 and 6-cylinder unit is the same.
The turbo pressure reaches 2500 bar, which is slightly more than on the 4-cylinder version. Two turbochargers are used, which significantly increases the performance of the engine. The exhaust system of the engine consists of a particulate filter and an SCR system. Also, the new R6 diesel is equipped with a combined exhaust system.
OM656 replaced the predecessor OM642. The engine is equipped with two camshafts with a variable valve timing, injection with a liquid reagent that effectively cleans the exhaust gases.

Description of the OM668 engine
The power unit is a diesel inline four with a volume of 1,7 liters. The motor is produced by the division of Mercedes-Benz - the Daimler company. The engine was installed on the W168 and W414 from 1997 to 2005.
Fuel injection OM668 Common Rail. Compared to the similar M166, 4 valves are used here instead of two. The gas distribution mechanism functions due to two overhead camshafts with a chain drive. The first circuit uses only the intake camshaft, the exhaust one is connected to it through a gearbox. The second chain rotates the oil pump, receiving power from the crankshaft.
All OM668 modifications are equipped with a turbocharger and produce more than 59 hp. With. An intercooler is responsible for cooling. At the initial stage (1997), this four-cylinder engine was the smallest Mercedes-Benz diesel. There are no mechanical differences between the versions, with the exception of a low-power 59-liter unit that works without a transitional intercooler. In 2001, the engines underwent restyling - the turbocharger and camshaft were slightly changed, which increased the rated power, but not the torque. The latter was a direct result of the poor grip of the W 168.
The engine has good potential - its power can be easily increased with one chip to 118 hp. With. At the same time, the motor resource does not suffer in any way, although due to the increased torque, the clutch may wear out soon.

Engine OM699
Turbocharged four, which is produced in collaboration with Renault-Nissan-Mitsubishi. This motor is also known as YS23.
The basic design was copied from the Renault M9T, but the engine turned out with a displacement increased to 2,3 liters. Also here is a different compression ratio (15,4) and a modified cylinder head. Modification DE23 LA is weak, while more powerful units are equipped with turbines. All motors comply with Euro 6 standards.

| Kai | Guys, I understood correctly that the new R4 and R6 motors with a 48V electric motor now work as an energy recuperator when braking (consider it as a generator), and as a starter when starting the engine |
| MegaPorsh | yes, there will be no belts and a conventional generator, now the condo and all sorts of other pumps work from it. True, due to what the boost occurs with a kickdown of 20ls, I did not understand from the text, should there be a battery? |
| Kai | No, the generator is just 12V, only all the blocks and the light remained 12V, and generators hang on the motors. Kick down is probably from the total recoil of the motor itself and the engine with an electric turbine))) Like there will be no lag now on Mers-Benz |
| It doesn't hold | I didn’t quite understand, if the new in-line will produce 408 forces, is this a replacement for the 500th models, ala cls and so on? then where will they put the modified m176 if it replaces the 4.7 engine, which was installed in the 500s models, but as I already wrote above, a new in-line 500 will go into the 6s |
| Vadim80 | well, I understood everything, 4.7 was of 2 types, for 408 forces and for 455 408 forces it will replace the new in-line 6, and 455 forces (s classes, gle) will replace this modified engine from amg gt |
| Kai | While the M176 is being put on Gelik, this is the only 500 with a new engine in MB today |
| Sham | R6 - will now stand on the 500th on Eska and Eshke coupe/sedan/kabrik |
| It doesn't hold | where will they stick the new 4.0 then, which came to replace the 4.7 455-strong one? and after all, it was 455 strong that was set ONLY in GLE / GLS / S / MAYBACH in simpler classes they put the same 4.7, but at 408 FORCE !!! (e / cls, etc.) I think 408 hp 4.7 will be replaced by R6, and more expensive models, which had 455 hp, will put a new 4.0!! because the new R6 is randomly matched in strength to its predecessor 4.7, it also has 408 forces |
| Kai | 330km/h is enough, 350km/h is already redundant, and 391km/h is no longer necessary |
| Yarik | The essence of the new R6 offers the performance of an eight-cylinder engine with much lower consumption. The new petrol engine (internal code: M 256) starts next year in the derneuen S-Class. |
| Vadim80 | Plastic EVERYWHERE and aluminum .... AS always limited mileage (programmed) Thousands per hundred MAXIMUM. Then all this will thunder, fly into containers ... “Iron”, as I understand it, will no longer be in diesel engines .... |
| Kai | Why do you always think about bad things |
| Vadim80 | Not bad. But you can see right away. That the resource is initially limited by the manufacturer. This is ALL initially NOT able to work more than 100 thousand km! |
| Volodya | the same “specialists” 5 years ago said exactly the same thing about the 651st engine - but nothing, even on sprinters it nurses 800 each. , in Europe 25tyr ...”) |
| The Crimean | Volodya, don't worry, the jambs will not be left without work |
| How | the rings have a motor for sq7 there is also an electric turbo, although there is a v8 diesel engine, it’s worth adding |
| Vadim80 | For some reason I don’t see smiles on the faces of the owners of ALL MB gasoline engines. Whatever the topic - PROBLEMS. And they change the oil on time and seem to be not slackers...and they could live. But apparently on Monday MB gave birth to them (the engines). Another example. The Merc has 30000 km, and it already has gasoline in the oil... is this normal? Yes, they (MB) cannot calculate our reality and conditions. Fuel is SHIT! That’s why I wrote about plastic and aluminum in blocks. Old engines could digest everything...new FIGs with oil. And it’s not just isolated cases. The MB is an ultra-modern car. Designed for civilization….we still have…PRAIRIE with the Papuans… |
| Kai | I have a different experience, nothing has ever happened to my motors, I don’t see the point in pessimistic moods. Once a friend of mine failed a compressor, but they changed it under warranty, this is the only thing I remember. As for plastic, it has long been present in the engine industry, both in conventional cars and in motorsport. Why did I decide, no, I’m just wondering what node or constructive solution prompted me to write such a conclusion? |
| The Crimean | I've been reading the Internet |
| Vadim80 | Cast iron is ALWAYS better than aluminum. |
| Kai | Which manufacturer is currently making cast iron blocks, give examples |
| Esthete | MAZ? |
| Or | hello/ so what will stand on the s400 cupe production on january 20th?? maybe postpone or Panama in the summer with a small engine, well, tell me what the guru should do? |
| Kai | What you like more, then take it, completely different carts |
| Or | so a new motor is possible? for s400 cupe / probably not earlier than March / significant discount for mv |
| Kai | I don’t think it’s more likely that the new motor will be after restyling |
| Vadim80 | What he wrote in his post ... that was confirmed by the “MBeshniks” themselves ... Progress for the sake of marketing and no more. In principle, if life is established. So it should be. infinity. And you feel good and them ... And if he was carrying cartridges? Does he have a plastic pallet? |
| Kai | Guys, what's the problem, there is a choice, and there are a bunch of other cars, well, if you think that MB is doing shit, buy from another manufacturer |
| Vadim80 | There is NO choice ... everything is so marketing .. to take off the dough. Everyone has it now. Nobody bothers with this resource now. A great resource is now a crime for corporations…not profitable. |
| Kai | Slu, Vadim, maybe it’s enough to carry hysteria, but the world has changed, everything else too, either live the old one, or you just need to accept what is now |
| Vadim80 | What kind of hysteria? God forbid. The world is so arranged now. Why can't we discuss it? Just giving now for a wheelbarrow from 4 million, somehow I want it to travel more .... To whom 4 million is not money .. in general, our sighs are on the drum ... |
| Kai | Yes, why not, it’s possible, we’re discussing it. It’s just that none of us have even driven it yet, and none of us have felt all the words of the MB-eschniks from the press release on ourselves. And we’re already declaring that everything is bad and shitty. Plastic in the MB didn’t appear yesterday , and a long time ago, it was actively implemented even when 220/215 bodies were in production, if not earlier. Well, the pan with a filter is made of plastic, well, the supports are made of plastic, well, the intake elements are made of plastic, so what! As for the resource, that is, characters that in 10-15 tkm can kill both the engine and gearbox 160 tkm, both a lot and a little, I agree, but in fact - 5-6 years, plus a guarantee of 2 or whatever years from MB. But I’m sure that with proper regular maintenance, even more will pass |
| moikotik | Guys, well, it’s written in Russian in white: “160 thousand km are standard for the auto industry.” Standard! That is, it is a certain settlement standard, incl. for engines that actually travel half a million kilometers. The problem is completely contrived. |
| Vadim80 | Is it customary to prostrate before the word MB??? And just praise-praise MB and despise other brands? I have a MB and so that it goes as it should and was comfortable. I had to make a noise-chip-tighten the interior. And these new engines are sure .. they will drink a lot of blood. One blow and a pipets pan ... .. Plastic cannot live long in our conditions. Especially in such places. MB has long hesitated for them. At least in oil filters. Nah, is he needed there? It's a pity for the metal? This is greed, not progress .... And what kind of “mileage” is 160 thousand ??? One laugh. When I traveled a lot around the country for work. to the parking lot ... what for then a car? A taxi is better ... |
| Or | but I won’t drag the s400 cupe and the Shumka too, and that now I don’t buy new models /// I always bought other brands and everything is ok |
| Szasik | Tell me, is it just me-déjà vu? ... Which engine was invented earlier - in-line or V-shaped? That is, everything new is a well-forgotten old? What is the “innovativeness” of the inline six (except for the penny cost of production)? It seems to me that those who anticipate the limited resource of new motors are right. An in-line engine is several times cheaper than a V-shaped one. Sorry, but an in-line six in an aluminum block is frank shit (just live 160 thousand). It is wrapped in cast iron with a screw, in aluminum it is not at all clear how it is going to live. Then the main “joy” of in-line engines is overheating of the distant cylinders from the pump (due to the length of the cooling path). How about going back to this? I think with only one goal - super profit. |
| Artyom | By the way, I have a question, guys, who took a new car and drove more than 160 thousand km on it without selling it? .... or even let it be, took a used one up to 30 thousand and drove more than 160? |
| Vadim80 | 260 thousand easily and not forced … and all that in 3.5 years. True in Japanese. |
| The Crimean | I drove 221122 diz 386tkm and it's okay |
| moikotik | Question only about MB? Or even? If the question is general, then I rode the SAAB (9-3rd) for 5,5 years, having rolled just almost 160000 km. The car both shot from new and continued to shoot, as it did not require topping up oil (not a gram) between maintenance, and continued not to require ... Yes, the service interval at SAAB is 20000 km (especially for hypochondriacs who change oil every 5000). In-line turbo four with an aluminum block, by the way |
