Innovative? How can petrol and diesel engines be called innovative? Many environmentalists, experts and other participants in the car market are probably perplexed. But it really is. The company introduced a new Mercedes Benz engines with innovative technologies for the updated S-Class, which produced in 2017.
Strange? But what about the electric engines, about which, probably, everything possible has already been said. Indeed, according to experts' forecasts and according to the plans of a number of leading countries of the world, the days of internal combustion engines are numbered. This is partly the case. But there is one thing. Electric vehicles are not expected to become mainstream, capturing a larger part of the market in immediate near future.
In order for electric vehicles to push cars with internal combustion engines out of the market, it will most likely take decades. And this is regardless of the fact that the authorities of Western countries want in the near future to get rid of vehicles operating on internal combustion engines. As much as many developed countries would not want this, but until the popularity of electric transport is overshadowed by gasoline and diesel cars, we will not see the decline of vehicles operating on traditional internal combustion engines.
That is why the company Mercedes continues to develop new gasoline and diesel engines for its future models.
As a result, the company Mercedes introduced five new engines of internal combustion engines, which launched in the S-class cars from 2017.
Mercedes is quite cautious about the topic of supercharged gasoline engines. To provide a smoother increase in power without the unpleasant effect of "turbo lag". The result was presented in 1995 in a mechanical compressor, driven by an ordinary ribbed belt. M 271.
The most widely used 1.8-liter version of the M 271 with a multipoint injection system with a variable degree of forcing: from 122 to 192 hp. In some models used a modification with direct fuel injection. It was produced in the period from 2003 to 2005 and developed a power of 170 hp. It can be recognized by the CGI label.
The use of engines 1.6-1.8 K / T (M 111, M 271). These engines were used only in Mercedes cars. They are always positioned longitudinally in front. All motors were assembled at only one plant in Germany.
New diesel engines Mercedes with four and six cylinders. Code designation of new four and six-cylinder diesel engines Mercedes: OM 656
Naturally, all the new engines of Mercedes 2017 have become even more economical and more powerful compared to their predecessors. However, in order to achieve these technical results, engineers have applied completely different technologies in the development of power units.
In fact, a new generation of Mercedes engines began to be introduced in the spring of 2016, when the German brand introduced a new two-liter diesel engine for the E-class. This engine consumes 13 percent less fuel than the previous similar power unit. Increasing the efficiency of the diesel engine was achieved by reducing the weight of the power unit, reconfiguring the software of the engine control unit, as well as reducing friction in the cylinders, thanks to the new special coating “Nano Slide”.
The new six-cylinder engine for the S-class, designated as OM 656, essentially represents an enlarged version of the four-cylinder engine for the E-class, which was introduced at the beginning of the year 2016.
Brand new six-cylinder diesel engine Mercedes, which is installed on the S-class from 2017, has a capacity of 313 hp. Remember that a similar engine of the previous generation gave out only 258 hp.
The six-cylinder diesel engine Mercedes 2017 is based on the four-cylinder engine OM 656, which is installed on the new E200 d in the back of the W213
This engine uses a similar enhanced emission control technology, which is used in four-cylinder power units installed on the 2.0-liter four-cylinder diesel E-classes.
For example, in a six-cylinder diesel engine, Mercedes engineers installed the CAMTRONIC system, which was previously used only on small powertrains. This system reduces the opening time of the intake valves at low engine speeds, which significantly saves fuel.
Diesel engine 200-220 CDI - OM 611. Short description.
In 1997, serious changes occurred in the history of Mercedes diesel engines: for the first time, a common-injection engine was used. It was used in the first generation Mercedes C-Class with a station wagon. At the same time the designation CDI appeared, which is used today.
The engine designation is OM 611. It has 4 cylinders and a working volume of 2.2 liters. The first samples developed 125 hp and 300 Nm of torque. Compared with the OM 604 predecessor, the new unit received a power increase of 30%, torque - by 100%, and fuel consumption has decreased by 10%. The injection system operates at a maximum pressure of 1350 bar. Initially, a turbocharger with a constant geometry was installed in the engines, and since 1999, a supercharger with an adjustable position of turbine blades began to be used. The volume 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, for each cylinder there are four valves.
The OM 611 engine family has several different modifications. In passenger cars (C and E-Class), an aggregate with marking 200 CDI (102-115 hp) and 220 CDI (124-143 hp) was used. In addition, there are variations 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 4-cylinder engine of the new generation OM 646 was introduced and its derivatives - 2.7-liter OM 647 and 3.2-liter OM 648. Despite the similar design, about 80% of the components new ones.
270/320 CDI (OM 612 / OM 613).
The next direction in the development of the OM 611 engine family was an increase in the number of cylinders. The 5-cylinder unit received the designation OM 612, and the 6-cylinder unit OM 613. The first with marking 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 of the 612 OHM with a capacity of 231 hp, intended for the C 30 CDI AMG.
Undoubtedly, the main attention of experts and those interested in new Mercedes engines should be focused on new gasoline engines. Of particular interest is the V6 petrol power unit M256, whose power will now be 408 hp. Torque more than 500 Nm. This was made possible by virtue of to the use of technologies that the company previously used Mercedes only on V8 petrol engines.
Thanks to innovations, engineers were able to reduce the fuel consumption of the new six-cylinder M256 engines by 15 percent, compared to previous power units, installed on the Mercedes S 400 (power 333 hp)
By the way, a 20 hp electric motor appeared between the crankshaft and the gearbox.
In fact, it is an integrated node, which is a generator and a starter in one component (ISG). That is, when necessary, the electric motor works as a starter and helps the engine achieve maximum torque at the very beginning of acceleration, which provides the car with maximum traction at low revs.
Also this unit can work as a generator, feeding a number of important vehicle equipment. The electric motor is powered by the energy produced during braking, which enters a special battery.
Each new Mercedes engine is distinguished by a variety of different technologies that have made the power units more powerful and much more economical than their predecessors. On average, each engine has become 5-10 percent more economical and 5-15 percent more powerful.
The most effective today is a diesel engine with a power of 258 hp, which is currently installed on the Mercedes S350 d. So this model has an average fuel consumption of 5.3 l / 100 km. of the way.
The new six-cylinder diesel engine, which will be installed on the S-class in 2017, will consume less than 5 liters per 100 km.
The latest engine introduced by Mercedes is the powerful V8 Bi-turbo AMG powerplant with a capacity of 4.0 liters and 476 hp. with a maximum torque of 700 Nm. Code designation of the motor M 176.
The new engine will replace the 4.8 liter V8 engine with 455 hp. Despite the increase in power, the new 4.0 liter eight-cylinder engine will be 10 percent more economical than its 4.8 liter predecessor.
This was made possible thanks to the CAMTRONIC technology (valve opening and closing optimization system), which is used in six-cylinder diesel engines. In addition, in the new eight-cylinder engine, a system of cylinder deactivation is used to save fuel (the second, third, fifth and eighth cylinders are disabled). This mode is active only in the “Comfort” and “Eco” modes at 3250 engine revolutions per minute.
