Mercedes-Benz M276 engine

Uncommon card · No. 139274

The Mercedes-Benz M276 engine is a gasoline direct injection automotive piston V6 engine. The M276 engine is not related to the Chrysler Pentastar engine except for the 60-degree angle, despite that it was developed while Chrysler was still owned by Daimler AG. This can be seen in its 60 degree vee–angle, as opposed to the 90-degree angle of its M272 predecessor. The 60 degree vee–angle eliminates the need for a balance shaft, improving refinement while reducing mechanical complexity. None of the parts are shared at all. The M276 engine features an aluminum engine block with Nanoslide cylinder coating and dual overhead camshafts with independent variable valve timing on 12 intake and 12 exhaust valves and a new 2–stage timing chain arrangement. The M276 also includes direct injection with piezo–electrically controlled injectors for 2 to 3 sprays per intake stroke in normal operation, multi–spark ignition that creates up to 4 sparks per cycle, and the demand–controlled fuel pump, water pump...
