Engine Mercedes OM442

Engine Mercedes OM442

Mercedes OM442 engines are V-type engines. They are distinguished by a wide range of modifications that cover almost the entire power range. These engines have 8 cylinders up to 130 mm in diameter with a pair of valves. They achieve high power ratings at low revs. With a rotational speed of 1800 rpm, they produce 408 hp (300 kW).

These units are equipped with a turbocharging system that allows them to be enlarged power with relatively small cylinder volumes.

This series of motors is designed to be fitted not only for Mercedes-Benz vehicles, but also for heavy trucks, road trains, agricultural vehicles, generators, and buses. The low operating speed of this series of motors reduces noise levels, which is an added benefit.
