Mercedes-Benz M110 engine


The M110 engine family is a DOHC 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 4A1 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 and a bore and stroke of. Firing order is 1-5-3-6-2-4. Amount of coolant in the radiator was from 1972 and from 1980s and on. Amount of oil in engine was. 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.

M110.921 / M110.931

The.931 is the low-compression version of the.921.
Applications:
The.932 is the low-compression version of the.922.
Power output of.922: at 5500 rpm.

Power output of.932: at 5500 rpm.
Applications:
Power output: at 5500 rpm, or at 5500 rpm for the low-compression version.
Applications:
Power output: at 5500 rpm, or at 5500 rpm for the low-compression version.
Applications:
Power output: at 5500 rpm, or at 5500 rpm for the low-compression version.
Applications:
The M110.981 uses Bosch D-Jetronic injection. This system senses the ambient temperature, engine temperature, intake manifold underpressure and throttle valve position and calculates with an analog computer how many milliseconds the fuel injectors should stay open per revolution.
The.991 is the low-compression version of the.981.
Power output of.981: at 6000 rpm and of torque at 4500 rpm.

Power output of.991: at 6000 rpm.
Applications:
The.992 is the low-compression version of the.982.
Power output of.982: at 6000 rpm.

Power output of.992: at 6000 rpm.
Applications:
The.993 is the low-compression version of the.983.
Power output of.983: at 6000 rpm.

Power output of.993: at 6000 rpm.
Applications:
The M110.984 was the first engine with the new Bosch K-Jetronic injection. This system is mechanical. The air that is taken in is weighed to the determine the amount of fuel to inject.
Power output: at 6000 rpm up to April 1978; at 5800 rpm from April 1978.
