Mercedes-Benz M119 engine

The Mercedes-Benz M119 is a V8 automobile petrol engine produced from 1989 through 1999. It was available in 4.2 L; 5.0 L; and 6.0 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 1997.

Chronology
PredecessorMercedes-Benz M117
SuccessorMercedes-Benz M113

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 aluminium 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 aluminium
  • An improved vibration damper system is used
  • The aluminium 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

4.2

edit

The 4.2 L (4,196 cc) version (M119.975) produced 275 hp (279 PS; 205 kW) at 5700 rpm and 400 N⋅m (295 lb⋅ft) of torque at 3900 rpm. Early versions of W140 400SE/400SEL (and potentially W124 400E for USA and Japan) produced 286 PS (210 kW; 282 bhp) at 5700 rpm and 410 N⋅m (302 lb⋅ft) of torque at 3900 rpm.[1][2][3] Rare Japanese version 400E 4.2 AMG (16-20 cars) has 312 PS (229 kW; 308 bhp).

5.0

edit
 
A twin-turbocharged M119 installed in a Mercedes-Benz C11 Group C race car.

The 5.0 L (4,973 cc) version produced 326 PS (240 kW; 322 bhp) at 5700 rpm and 480 N⋅m (354 lb⋅ft) of torque at 3900 rpm. Later engines had the full throttle enrichment removed and power was a little less, to 315 hp (319 PS; 235 kW). The E50 AMG M119.985 produced 354 PS (260 kW; 349 hp) @ 5,550 rpm and 481 N⋅m (355 lb⋅ft) @ 3,200 rpm.

Applications:

The 5.0 L M119 replaced the M120 V12 in the CLK-GTR race car, for the new generation CLK-LM which then won every race in the FIA GT series, which ultimately resulted in the GT1 class being canceled.

It also won the 1989 24 Hours of Le Mans in the Sauber C9 and was further used in the Mercedes-Benz C11 before being replaced by the M291 in 1991.

6.0

edit

The M119 fitted into AMG models produced around 375 hp (380 PS; 280 kW) to 415 PS (305 kW; 409 hp) and 580 N⋅m (428 lb⋅ft) of torque.

For 1994 model year, there were also limited AMG models for Japan which were sold between October 1993 and September 1999 in left-hand drive. Installed engine was M119.970 which displaced 6.0 L (5,956 cc), power 381 PS (280 kW; 376 hp), and 59.1 kg⋅m (580 N⋅m; 427 lb⋅ft) of torque.
