. Three variants of the engine were built: a model, a version built for the US market, and a for commercial vehicles. The first two were rated by the manufacturer for at 4200 RPM and of torque at 2800 RPM; the increase in displacement reduced emissions in order to meet US automobile emissions requirements. The commercial vehicle version had in standard variants, the turbocharged version (OM601.970) in the V230 TD and Vito 110D had . It is closely related to the 5 cylinder OM602 and the 6 cylinder OM603 engine families of the same era. The OM601 was built with an aluminum head on an iron block. The camshaft and fuel injection pump are driven by a duplex chain from the crankshaft. A separate single row chain drives the oil pump from the crankshaft. Fuel supply is
