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.

It is the heir to the M113 series. When creating the M273 E55 engine, the six-cylinder M272 E35 was taken as a basis, the cylinder block of which was modified for the V8 configuration, the cylinders increased in diameter, a long-stroke crankshaft was installed, the inter-cylinder distance remained the same – 106 mm.

Engine Mercedes M113 E50
The M113 E50 engine is an unusually lightweight, compact engine (unlike its predecessor M119) was a continuation of the line of three-valve M112 engines. The engineers added two more to the six cylinders and got the M113. Due to its compactness, it was installed on all rear- and all-wheel drive Mercedes models. Each cylinder has three valves (two inlet and one outlet), and in the M113 engine, the area of the outlet valve is 30% less than the total area of the two outlet valves in its predecessor, in addition, it has less weight (the rod is filled with sodium).

The 5.0-liter power unit M119 E50 became the first in the M119 family and is located in a row between the younger version of the E42 and the sports modifications of the E60 AMG and E63 AMG. In the new engine, a 90-degree aluminum bore was used, plus pistons from light alloys and forged connecting rods were used. Continue reading Engine Mercedes M119 E50
Engine Mercedes M103 E30
Released in 1985, the inline six-cylinder M103 E30 engine was intended to replace the outdated M110 engine in all respects and was partially unified with the four-cylinder M102 2l. The next M103 series (which also included the 2.6-liter M103 E26) received a new lightweight cast iron cylinder block and a 12-valve block head with one camshaft and hydraulic lifters, instead of the previous 24-valve two-shaft, which was due to the desire to increase efficiency, reduce power plant weight and production costs.

Engine Mercedes M104 E28
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”). Continue reading Engine Mercedes M104 E28
Engine Mercedes M104 E30
The M104 E30 engine had 2 overhead camshafts, with 4 valves per cylinder. The shafts were driven by a roller chain. There was a variable valve timing. As you know, sports cars had such a scheme of all kinematics. Motors Mercedes M104 E30 have proven to be reliable devices (with minor flaws). Continue reading Engine Mercedes M104 E30
Engine Mercedes M112 E28
The Mercedes M112 engine is a family of V6 engines that were widely used in the 2000s. Released in 1998, the Mercedes M112 was the first V6 ever built by Mercedes. Some time later, the Mercedes M113 V8 engine was designed on its basis. All M112 engines were built in Bad Cannstatt, Germany, except for supercharged versions from AMG – E32 AMG, which were assembled in Affalterbach, Germany. Continue reading Engine Mercedes M112 E28
