BMW M42

The M42 is a standard developed by BMW petrol engine with four-valve technology. This had four cylinder, two overhead camshafts, a displacement of 1795 cc, an initial output of 100 kW ( 136 hp ) at 6000 rpm and a torque of 172 Nm delivered at 4600 rpm. The compaction was 10.0 - the engine had to therefore be operated with 95 octane Super. Instead of the toothed belt like used in these years he had a timing chain for the valve train and a "dormant spark distribution " with four ignition modules; a failure prone ignition distributor was therefore no longer available.

Before the M42 BMW engines were used with four-valve technology with a few exceptions ( 320is E30 and 745i E23 South Africa) only in models of BMW Motorsport GmbH, such as in the BMW M1, M635 CSI and M3 etc. The M42 was thus the first four-valve engine, the BMW implanted not in a high-priced M- model, but in a mass-produced car.

He was presented in autumn 1989 as a 318is in the face-lifted BMW E30 body. The car was only two doors available - M- Technic sport steering wheel, Shadowline, 14 " wheel covers, front and rear spoiler, M -Technic sports suspension and disc brakes on the rear axle, and holds ventilated front disc brakes were standard.

He was later installed in the E36 318is in the sedan, coupe and the compact variant 318ti and performed thanks to a modified intake system now 103 kW ( 140 hp ) at 6000 rpm and had a torque of 175 Nm at 4500 rpm.

The direct successor of the M42, the M44 (BMW M44 B19 ). He had the same power, but a larger engine displacement of 1895 cc and a higher torque of 180 Nm.
