Three variants of the engine were built, a 2.0 L; 120.6 in3 (1,977 cc) model, a 2.2 L; 134.1 in3 (2,197 cc) version built for the US market and a 2.3 L; 140.3 in3 (2,299 cc) for commercial vehicles. The first two were rated by the manufacturer for 72 bhp (54 kW) at 4200 RPM and 96 lb⋅ft (130 N⋅m) of torque at 2800 RPM; the increase in displacement reduced emissions in order to meet US automobile emissions requirements. The commercial vehicle version had 78 bhp (58 kW) in standard variants, the turbocharged version (OM601.970) in the V230 TD and Vito 110D had 96 bhp (72 kW).
The OM601 was built with an aluminum head on an iron block.
The camshafts 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 indirect injection via a prechamber arrangement. The OM-601's injection pump is a mechanical fuel injection unit with a 5,150 RPM (+ or - 50 RPM) mechanical governor, automatic altitude compensation, and a 'load sensing' automatic idle speed control. The pump is lubricated by a connection to the engine oil circulation.
Use of the block heater was recommended in climates where it drops below 10 °F (−12 °C) for long periods.
