What kind of ignition system does a M104 have?
The 3.2 liter M104 engine uses a different ignition system – HFM (hot-film mass air flow sensor), fully electronic with integrated electronic ignition and sequential fuel injection. This system combines fuel injection and ignition control in one module.
Is the cylinder head the same as the M104?
The cylinder head is the same as M104 E30 with four valves per cylinder. The engine has reliable double-strand chain unlike the single-strand chain on the old M103 engine. In 1992 the engine got variable geometry intake manifold.
What’s the difference between a M104 and a 3.2L?
It appeared in 1991. The 3.0-liter M104 was the start point for the new 3.2l version. The main differences are the new cylinder block, new 89.9 mm pistons and new crankshaft with bigger 84 mm stroke. The cylinder head is the same as M104 E30 with four valves per cylinder.
What kind of engine does a Mercedes M104 have?
The stroke is 73.5 mm (2.3-liter version has 89.0 mm stroke). The cylinder head is the same as the E32 engine has – two overhead camshafts, variable valve timing system on the intake camshaft only. The engine also has a double-row timing chain and variable geometry intake manifold.

What is the compression ratio of a M104 engine?
Bore is 89.9 mm (3.54 in) and stroke is 84 mm (3.31 in). On all 24 valve M104 engines Intake valves are 35 mm (1.4 in) and the exhaust valves are 31 mm (1.2 in). The Compression ratio is the same 10.0:1 on all W210, R129,and W140 but it did differ from 9.2:1 to 10.0:1 on W124 (M104.992).
