Mercedes revolution. Brand unveils four new engines for 2017, gasoline and diesel, shortly after his future car show Electrified proposal. And with many new features ...
Mercedes, which invented the automobile 130 years ago, seems to be clear that the combustion engine will still live many years. So the best thing you can do in this response to many needs it is to evolve offer lower consumption, less pollution and higher performance. Against odds, after ten years of V6 engines, Mercedes has decided to return to six-cylinder engines online. And incidentally shown developments in their conventional configurations, four-cylinder V8.
Mercedes: inline six-cylinder as BMW
that placing the cylinder V is over, the completely occupy the space under the hood with a wider and compact engine. Mercedes returns to its usual configuration, that rival BMW never left. If you want to achieve excellence in vibration, as befits a car luxury or whatwhat better solution than more balanced engine architecture? In addition, Mercedes returns to the inline-six both diesel and gasoline.
Gasoline particulate filter
Other manufacturers like Volkswagen had also announced, but it will be in 2017 when we see the First Mercedes gasoline particulate filter. It will debut in the M256 engine, an inline six-cylinder three liter, in S. Class
RDE future approval testing, with tests measuring contaminants in open traffic and a wide range of operating temperatures, will reveal that gasoline engines direct injection also produce particles, even if they are smaller than those of Diesel. Mercedes intended address it through this particle filter technique dominated years in diesel.
48 volts serve to shorten the engine ...
If the main drawback of the six-cylinder engine was its length "invasive"Mercedes it has Electrified 48 volts, removing the auxiliary belt in the front. Shorten the engine design factors involved, such as its reduced diameter pistons (In exchange for a long career), which allows them closer to each other.
With 48 volt feeds the conditioner compressor, water pump, the starter-alternator ... and supercharging system: An electric compressor is able to reach 70,000 rpm in 0.3 seconds. It is not the first car with an electric turbo, because we've already seen in an Audi SQ7. Announces that nullifies the delayed response of the turbochargers and with a displacement of three liters Mercedes proclamation get 300 kW (408 hp) and 500 Nm (51 Nm), figures equivalent to the current V8, but with fuel consumption fifteen percent lower than the current V6. The starter-alternator system 48 volt operation gets immediate and soft stop-start phases, behave well as a hybrid. In its mild hybrid mode retention and recovering braking energy, but also stops the engine when the car is launched in light descent and It can provide 15 kW (20 hp) motor supplementary. It is noteworthy that this motor-alternator for the first time is entrusted with the idle speed function. We do not know if stability is sought or facilitate a stable idle, but under, without both enrich the mixture during the heating phase motor, which could lead to lower consumption over short distances. Otherwise, in conditions "normal" idling does not exist because the engine will automatically stop at traffic lights. Or to go rolling inertia engine does not turn off completely and circulate in extra small idle ... we will already clarified.
Four cylinder turbo twin-scroll
From the same family as six cylinder 'gasoline, Mercedes released in 2017 one to two liters of up to 200 kW (272 hp) with internal code M 264. employ a power architecture 48 volts, but will not have electric boost, but a twin-scroll turbo as the current four-cylinder engine. The rest des specifications is similar to his brother six-cylinder, Electric motor-alternator support up to 2500 rpm and a retention and Power recovery up to 12.5 kW.
AMG V8 gasoline cylinder shutdown
Mercedes called internal code M176 in a new V8 developed by AMG biturbo, with the goal of being one of the most frugal V8. It not intended as a sport, but AMG applies knowledge to reduce friction (for example, treatment Nanoslide on cylinder walls) and other power losses. Improvements are lower than in the six-cylinder 350 kW (476 horse) and maximum torque of 700 Nm (71.4 mkg), because consumption low "alone" ten percent relative to current, with 26 horses less. The key to reducing consumption comes from Deactivation of the four central cylinders at low load below 3250 rpm.
Despite being aluminum construction technology block allow maximum pressure of 140 bars, the stuff of the first direct injection diesel, which now resist about 200 bars. The injection pressure is variable between 100 and 200 bars. The tubocompresores are located in the center of the V formed by the motor.
Also six-cylinder Diesel
From the same family as the engine premiered by Mercedes E220d born in 2016 six-cylinder OM 656. Jump to the figure 313 horses (230 kW), from 258 horses, while low oil consumption by seven percent. If you think that there will be technological advances sought drastic decrease is mitigated you mess up, it's so they were already low consumption of Bluetec. For example, the new six-cylinder Diesel employs steel pistons, as already he started making their smaller engines, Renault source. True, it is not "the last", Not the shape of the camera debut in the four cylinder E220 d, nor Nanoslide treatment. Its injection pressure 2,050 bar 2500 is far from some rival.
