Mercedes-Benz M119 engine
From Wikipedia, the free encyclopedia
The Mercedes-Benz M119 was a V8 automobile engine produced from 1990 through 1999. It was available in 4.2 L and 5.0 L displacements. It was a double overhead cam design with 4 valves per cylinder and variable valve timing on the intake side. It was replaced by the 3-valve M113 starting in 1999.
The M119 differed from the M117 in the following ways:
- The engine block uses asbestos-free gaskets and has better oil flow
- The cylinder head is now a 4-valve aluminum unit with dual overhead camshafts
- The connecting rods are forged and enable cooling of the pistons with sprayed oil
- The pistons are iron-coated cast aluminum
- An improved vibration damper system is used
- The aluminum oil pan has bolted-on oil baffles to prevent foaming of the engine oil
- The intake camshaft timing is adjusted hydro-mechanically up to 20°:
- 0–2000 rpm — retarded for improved idle and cylinder scavenging
- 2000–4700 rpm — advanced for increased torque
- 4700– rpm — retarded for improved volumetric efficiency
