The BMWM43 is an SOHC four-cylinder petrol engine which was produced from 1991-2002.[1] The M43 powered base-model cars, while higher performance models at the time were powered by the BMW M42 and BMW M44 DOHC engines. The M43 was produced at the Steyr engine plant.[2]
Compared with its BMW M40 predecessor, the M43 features both a camshaft position sensor and a knock sensor[3] as well as roller rockers and a timing chain (instead of the M40's finger rockers and timing belt).[4][5] It also features a dual length intake manifold[6] ("DISA"), to provide torque across a wider rev range.[7]
In 1998 the displacement was increased to 1,895 cc (115.6 cu in), increasing torque to 180 N⋅m (133 lb⋅ft) at 3900 rpm.[1]
The 1,596 cc (97.4 cu in) M43B16 produces 75 kW (101 hp) and 150 N⋅m (111 lb⋅ft) of torque. It uses the Bosch Motronic 1.7.x and Bosch BMS43 engine management system.[8] There was also a natural gas-powered version of this car (also able to run on petrol) for the 1995 BMW 316g Compact.
The M43B18 has a 1,796 cc (109.6 cu in) displacement. It produces 85 kW (114 hp) and 124 lb⋅ft (168 N⋅m) and uses the Bosch Motronic 1.7.1 fuel injection system.[8] There was also a less powerful natural gas-powered version of this car (also able to run on petrol) for the BMW 518g Touring (E34). This model was only available for two years.
The M43B19 (also known as the "M43TÜ") is the largest M43 engine, with a displacement of 1,895 cc (115.6 cu in). It produces up to 87 kW (117 hp) and 180 N⋅m (133 lb⋅ft), and uses BMW's BMS 46 engine management system.[8] The 77 kW (105 PS) versions do not have the DISA intake manifold and also have a smaller camshaft compared to the 118 PS versions. Note the M43B16, M43B18 and the M43B19 (118 PS version) all have the same camshaft.
