Engine Mercedes M104 E32

Mercedes Benz М104 is a 6-cylinder in-line engine with a cast iron block with a volume (respectively) of 3.0 l and 3.2 l with variable valve timing. Replaced a motor marked M103. 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”). Continue reading Engine Mercedes M104 E32

Engine Mercedes M272 KE/DE 35

The M272 E 35 power unit was the evolution of the Mercedes V6 and was supposed to replace the M112 E32 and M112 E37. In addition to the 3.5-liter engine, the lineup includes the 2.5-liter M272 E25 and the 3.0-liter M272 E30. The development of the 272 series was carried out on the basis of the M112, which includes an aluminum BC with a camber of 90 degrees and 106 mm between the cylinders. Silumin steel piston liners with a diameter of 92.6 mm. And the new crankshaft received 86 mm of travel. The pistons and forged connecting rods are somewhat lighter.
