The Mercedes Benz OM352 Engine is a 5657 cm2 (5.7 litres) displacement inline 6 cylinder 4 stroke motor. The engine utilizes diesel fuel delivered in a direct injection method from a Bosch PES style inline injection pump to the combustion chamber.
Common output power can vary from 60 kW to 124 kW (80 to 168 hp) depending on the fuel delivery and air charge options.
Below is listed the specifications for a 130 hp OM352, model 353.961. This variant is commonly used in Mercedes Benz Unimog , such as the U1100 and U1300 models.
