The Mercedes M272 E30 engine occupies a place between the M272 E35 and M272 E25, the main purpose of the model is to replace the outdated M112 E28. The M272 E30 aluminum V-shaped (camber 90°) engine block is similar to that used in the E35, but with smaller cylinders and a short-stroke crankshaft.
The cylinder heads are similar to the E35: aluminum with two camshafts (DOHC) and 4 valves per cylinder, the diameter of the intake valves is reduced to 37 mm, exhaust to 28 mm. Everything also uses a continuously variable valve timing system on the intake and exhaust shafts, hydraulic lifters, a two-stage intake manifold with variable length.
The timing drive uses a double roller chain, its service life is about 150 thousand km. Bosch ME control system 9.7.
