Overview Production 1977–1993 Layout Configuration Straight-6 Displacement 2.0–2.7 L (122–165 cu in) Block material Cast iron Head material Aluminium Valvetrain SOHC Combustion Fuel type Petrol Chronology Predecessor None Successor BMW M50

The BMW M20 is a SOHC straight-six petrol engine which was produced from 1977 to 1993. It was introduced eight years after the larger BMW M30 straight-six engine, which remained in production alongside the M20.[1]

The first cars to use the M20 were the E12 5 Series and the E21 3 Series. The initial M20 model had a displacement of 2.0 L (122 cu in), with later versions having displacements of up to 2.7 L (165 cu in).[2]

The M20 began to be phased out following the introduction of the M50 engine in 1990. The final M20 engines were fitted to the E30 3 Series wagon (estate) and convertible model built in April 1993.[3]

The M20 was the basis for the BMW M21 diesel engine.[4] It is also loosely related to the BMW M70 V12 petrol engine. Contents

History

By the 1970s, BMW felt the need for a six-cylinder engine smaller than the BMW M30, to use in the 3 Series and 5 Series.[5]:?92? The resulting M20 had a displacement of 2.0 L (122 cu in), BMW's smallest straight-six engine of its day. BMW presented the M20 engine at the 1977 IAA as a 90 kW 2.0-litre Solex 4A1 carburetted version, and as a 105 kW 2.3-litre K-Jetronic multi-point injected version.[6] Later versions had displacements up to 2.7 L (165 cu in). The M20 was used in the E12 5 Series, E21 3 Series, E28 5 Series, E30 3 Series and E34 5 Series.

Early versions of the M20 were sometimes referred to as the "M60",[7][8] although the M60 designation has since been re-used for a V8 engine produced from 1992 to 1996. Design

As per the M30, the M20 has an iron block, aluminium head and a SOHC valvetrain with 2 valves per cylinder.[9] It has a traditional rocker arm design and no hydraulic tappets.[10] The major differences to the M30 are:

A timing belt rather than a timing chain[11] Bore spacing of 91 mm (3.6 in), rather than 100 mm (3.9 in)[12] Slant angle of 20 degrees, compared with 30 degrees for the M30.[13]

M20B25

In 1985, the M20B25 replaced the M20B23. The M20B25 has a capacity of 2,494 cc (152.2 cu in) and initially produced 126 kW (171 PS; 169 hp) (without a catalytic converter).[31] It has an upgraded cylinder head (known as "885"), a bore of 84 mm (3.31 in), a stroke of 75 mm (2.95 in), pression ratio of 9.4:1, a redline of 6,500 rpm and uses Bosch Motronic 1.1 engine management.[32][23]

In 1987, a catalyzed model with Motronic 1.3 engine management was introduced.[33][23] pression ratio was reduced to 8.8:1 but thanks to the more sophisticated electronics power remained nearly as before, at 125 kW (170 PS; 168 hp). The uncatalyzed engine was kept in production for Southern Europe and other markets where unleaded petrol was not regularly available.
