The Mercedes-Benz M119 was a V8 automobile engine produced from 1989 through 1999. It was available in 4.2 L; 5.0 L; and 6.0 L displacements. It was replaced by the 3-valve M113 starting in 1997.
The M119 replace the M117 engine in 1989. Initially, the M119 engine had a Bosch LH-Jetronic
(‘Luftmasse-Hitzdraht’) injection control with a hot wire air mass meter, two ignition coils and
two distributors (one for each cylinder bank) and was controlled by an ignition control module. The M119 engine had an
aluminum alloy block with
Alusil-coated cylinder walls, an aluminum alloy cylinder head, forged
connecting rods, iron-coated cast aluminum pistons, double overhead cam (chain-driven) design
with 4 valves per cylinder and variable valve timing on the intake side, and hydraulic bucket tappets. While the M119 E 42 had a
compression ratio of 11.0:1, the M119 E 50 and E 60 engines had a
compression ratio of 10.0:1.
The M119 engine also featured two-stage intake camshaft phasing that could be adjusted hydro-mechanically by up to 20 degrees:
- From 0-2000 rpm, timing was retarded for improved idle and cylinder scavenging;
- From 2000-4700 rpm, timing was advanced for greater torque;
- Beyond 4700 rpm, timing was retarded for improved volumetric efficiency.
Around 1995 (depending on model), the distributors were replaced by coil packs (i.e. electronic distributorless ignition) where each plug had its own coil wire and Bosch ME injection was introduced. For the M119 E50 engine, this change was signified by the change in engine code from 119.970 to 119.980. For the M119 E42 engine, the code changed from 119.971 to 119.981.
