Information on The 4 Cylinder Inline M 274 Engine | Mercedes-Benz
In June 2012, the new M 274 4-cylinder gasoline engine with direct injection and turbocharging was introduced for the first time with the modification year of model series 204. The M 274 forms an engine family together with the transverse-mounted M 270 engine model series installed in model series 246. It is available in model series 204 as a 1.6 l displace- ment variant with 115 kW. This new engine family replaced the very successful major assemblies of engine model series M 271 EVO. The new direct injection system combines an extremely fast and accurate injector with a new, spray-guided combustion system. The M 274 engine model series fulfills the increasingly strict CO2 limits while also providing high torque, engine power and particularly comfortable noise and vibration characteristics. The use of flexible technology modules has made it possible to reduce consumption and untreated emis- sions. They allow varying worldwide market-specific and legal requirements to be fulfilled as well as ensuring the future of the engine family. Supplementing the technology portfolio is a coolant thermal management system to regulate the coolant circuit during the warm-up phase. The regulated vane-type oil pump with map-controlled two-stage control pressure allows the lubrication and cooling points in the engine to be supplied with a significantly lower operating energy input than would be possible with an unregulated pump. Compared to the predecessor M 271 EVO, a lower engine weight and lower friction power contribute to energy efficiency. This is supplemented by controlled ancillaries and the standard ECO start/stop function. – This printout will not be recorded by the update service. Status:
