Diesel 6-cylinder engine E300D (Mercedes-Benz E-Class W210)

At the request of customers, Mercedes-Benz also produced a 6-cylinder diesel engine E 300 D with a capacity of 3.0 liters, designated on the domestic market as OM 606. This model has tangible advantages due to reduced noise and vibration. Thus, the noise from the engine in the car interior of the E 300 D is even lower than that of the model with a gasoline in-line 6-cylinder engine.

Technically, the E 300 D diesel engine corresponds to the 4-cylinder E 220 D diesel engine (OM 604) with a volume of 2.2 l, but to a greater extent to the 5-cylinder E 250 D diesel engine (OM 605): 4-valve cylinder head with a prechamber, electronically controlled in-line fuel injection pump connected to the CAN bus, 2-mass flywheel in models with a manual transmission. The crankshaft of the 6-cylinder engine has seven main bearings. A distinctive feature of the E 300 D diesel engine is the adjustable air supply system, which is a three-stage resonance pipe with movable flaps and a length that changes depending on the speed. The suction length is maximum at low speeds, when optimal boost is required, and decreases as power increases.

Both the E 220 D and E 250 D diesel engines and the E 300 D have a catalytic analyzer that ensures environmentally acceptable exhaust emissions. The emissions of harmful substances in 4-valve diesel models are one third lower than in 2-valve models, which reduces the toxicity of exhaust gases by 20%.
