Mercedes-Benz new range of six-cylinder engines

Economical, clean, compact and lightweight is what Mercedes-Benz's new range of heavy-duty truck and bus engines is all about. The OM 470 engines will be manufactured from June 2012 at the company's Mannheim (Germany) engine plant, marking an expansion of the company's 'New Engine Generation' through the addition of 'BlueEfficiency Power'.

This new vertically mounted six-cylinder, in-line OM 470 engine with a displacement of 10.7 litres spans an output range from 240 kW (326PS) to 315 kW (428PS) and is in compliance with the future emissions standard Euro VI.

The new engine is built on the basis of the trailblazing heavy-duty OM 471 model series launched last year. However, with an eye on its specific use in trucks and buses, it has a few individual touches of its own. With a weight of just 990 kg according to DIN 70020-A, the new OM 470 is the ideal engine for use in weight-critical situations.

The OM 470 will be available in four versions for following trucks:

For urban buses, the OM 470 is available in two output and torque combinations:

For rural-services buses and touring coaches, Mercedes-Benz produces the new OM 470 in three versions:

A high level of economic efficiency is a key feature of the new OM 470, which is achieved with the help of the auxiliary components such as the closed-loop coolant pump and the air compressor.

Another key factor contributing to the engine's overall economic efficiency is the extension of the service intervals to as much as 1,50,000 km in long-distance transport operations. The particulate filter is maintenance-free up to 4,50,000 km of operational use. Ease of maintenance also helps to reduce costs.
