Engine Mercedes OM442

Engine Mercedes OM442

Mersedes 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.

Mercedes OM442In addition to the models OM 442 A (260 kW) and OM 442 LA (320 kW), introduced back in 1985, Daimler-Benz introduced new diesel engines for commercial vehicles of the 400 series with outputs from 160 to 353 kW. 6- and 8-cylinder V-engines.

The combustion system and mechanical systems were developed. At the same time, Daimler-Benz introduced a V6 diesel engine with direct injection and constant angular ignition timing for commercial vehicles.
