Engine Mercedes M271 E18 ML/AL

The M271 E18 ML / AL engine is an in-line 4-cylinder petrol internal combustion engine with a displacement of 1796 cm3 that is the same for all modifications. The M271 E18 engine is distinguished by the method of injecting the air-fuel mixture into the cylinders: on the M271 modification, the mixture flows from the nozzles into the intake manifold to the intake valves, on the M271 E18 modification, the fuel is injected directly into the engine combustion chamber.

Engine Mercedes OM612

The Mercedes Benz OM612 engine is a 5-cylinder diesel engine with 2 overhead camshafts that drive 20 valves through pushrods. Compared to its predecessor OM604, it has 30% more power, 50% more torque and 10% less fuel consumption. An oxidation catalyst is used to clean the outlet gases. As the efficiency of the new generation engines was increased, there was not enough heat to heat the passenger compartment at low temperatures. Continue reading Engine Mercedes OM612

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.

Engine Mercedes M273 E55/E46

The Mercedes M273 engine debuted in the S-class car in the fall of 2005 and was subsequently installed on the E-, S-, CLS-, R-, CL-, SL- and CLK-class models, as well as off-road vehicles of the ML, GL and G series. family of gasoline V-shaped 8-cylinder internal combustion engines from Mercedes-Benz. 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).

Engine Mercedes M111 E20/E20 ML

Back in 1992, the outdated 4-cylinder E20 engine from the M102 engine series was replaced by the M111 series engines. The new M111 line includes such legendary engines as M111E18, M111E22 and M111E23. The new 2.0-liter engine differed from its predecessor first of all: a completely new cylinder block, which was made of cast iron, a new crankshaft, as well as a new connecting rod and piston group. On the M111 E20 engine, the cylinder head had 4 valves per cylinder and two camshafts. The design provided for a place for hydraulic lifters, as well as an electronic fuel injection system.

Engine Mercedes M111 E23/E23 ML

In 1995, the last and most voluminous engine in the M111 line of engines came out – this is a 2.3-liter M111 E23 engine. It was intended to replace the completely outdated M102 E23 engine technology. At the heart of the E23 is a cast iron cylinder block, with a bore of 90.9 mm, the piston stroke was increased to 88.4 mm, which is 7.9 mm more than in the 2.0-liter version.
