The M104 E28 engine is a 2.8 or 3.2 liter inline 6-cylinder engine. There was also a 3.6-liter AMG version. The engine had two camshafts and 4 valves per cylinder. On engines without an ignition distributor, the intake camshaft was equipped with an electro-hydraulic clutch to change the valve timing. The phase change took place without smooth adjustment – only two extreme positions (“earlier” – “later”).
