Mercedes-Benz introduces new generation OM 470 diesel engine

25 June 2016

Mercedes-Benz announced a new generation of the OM 470 diesel engine with new developments to achieve a further reduction in fuel consumption. A new top-of-the-range variant with a power output of 335 kW (456 hp) is also being introduced. The engine will be exhibited in the Mercedes Actros truck at the IAA show in Hannover.

The six-cylinder in-line Euro VI engine with a displacement of 10.7 L benefits both from technical refinements of the larger OM 471 (12.8 L) which were introduced last year and from technology specific to the compact model series.

The OM 470 is the most compact of the heavy-duty engines from Mercedes-Benz. It features all the major characteristics of the bigger OM 471, such as steel pistons, two overhead camshafts, asymmetric exhaust-gas turbocharger, powerful engine brake and the X-Pulse common rail injection system with pressure booster.

With the addition of the new top-of-the-range variant, the OM 470 family includes five engine variants, from 240 kW (326 hp) at 1600 rpm / 1700 Nm at 1100 rpm to 335 kW (456 hp) at 1600 rpm / 2200 Nm at 1100 rpm. The OM 470 is intended for such applications as tank vehicles, rigid trucks or construction transport, while the larger OM 471 engine is designed for long-haul transport.

Some of the key design features of the OM 470 (some shared with the OM 471) are:
