Encyclopedia
The M110 engine family is a DOHC (double overhead cam) design with 2 valves per cylinder straight-6
automobile engine made by Mercedes-Benz
in the 1970s and 1980s.
The M110.92x and .93x engines are carburetor engines, with Solex
or Pierburg carburetor
.
The M110.98x and .99x engines are fuel-injected engines, with Bosch
D-Jetronic up to the .983 and K-Jetronic from the .984.
All M110 engines have a displacement of 2.8 L (2746 cc) (170.8 cu in) and an 86 mm bore and 78.8 mm stroke. Firing order is 1-5-3-6-2-4. Amount of coolant in the radiator was 11 litres from 1970s and 12 litres from 1980s and on. Amount of oil (lubricant) in engine was 6 litres. Lubrication system was pressure circulation lubrication system. Number of valves was 1 intake, 1 exhaust with V-shaped overhead configuration. Valve operation was 2 top camshafts and camshaft drive was duplex roller-type chain.
The M110 .92x and .93x carburetor engines were replaced by the SOHC 2.6L M103
while .98x and .99x fuel-injected engines were replaced by 3.0L M103
starting in 1986.
