Chronology
Predecessor Mercedes-Benz OM616
Successor Mercedes-Benz OM604 engine

The Mercedes-Benz OM601 engine is a 4 cylinder diesel automobile engine that was manufactured by Mercedes-Benz.

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).

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 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.

The engine was used in the 208D 308D and 408D Mercedes-Benz T1 and later the Phase 1 308D Mercedes-Benz Sprinter

BMC A-series engine Motor vehicle engine

Austin Motor Company's small straight-4 automobile engine, the A series, is one of the most common in the world. Launched in 1951 with the Austin A30, production lasted until 2000 in the Mini. It used a cast-iron block and cylinder head, and a steel crankshaft with 3 main bearings. The camshaft ran in the cylinder block, driven by a single-row chain for most applications, and with tappets sliding in the block, accessible through pressed steel side covers for most applications, and with overhead valves operated through rockers. The cylinder head for the overhead-valve version of the A-series engine was designed by Harry Weslake – a cylinder head specialist famed for his involvement in SS (Jaguar) engines and several F1-title winning engines. Although a "clean sheet" design, the A series owed much to established Austin engine design practise, resembling in general design and overall appearance a scaled-down version of the 1200cc overhead-valve engine first seen in the Austin A40 Devon which would form the basis of the later B-series engine.

Mercedes-Benz OM616 engine Motor vehicle engine

The OM616 engine family is a diesel automobile Inline-four engine from Mercedes-Benz used in the 1970s and 1980s, and produced by Force Motors in India from the 1980s to the present.

Mercedes-Benz OM617 engine Motor vehicle engine

The OM617 engine family is a straight-5 diesel automobile engine from Mercedes-Benz used in the 1970s and 1980s. It is a direct development from the straight-4 OM616. It was sold in vehicles from 1974 to 1991. The OM617 is considered to be one of the most reliable engines ever produced with engines often reaching over 1,000,000 km (620,000 mi) without being rebuilt and is one of the key reasons for Mercedes' popularity in North America in the 1980s, as it was powerful and reliable compared to other automotive diesels of the time. It is also a very popular choice for the use of alternative fuels, mainly straight or waste vegetable oil and biodiesel, although the use of these fuels may cause engine damage over time if not processed properly before use.
