Applications:

• 1993–2000 C 180 (W202)

The M111.940{{cite web|url=https://mercedes-benz-publicarchive.com/marsClassic/en/instance/ko/200-CE-M-111-engine--C-124-E-202-1992---1993.xhtml?oid=4598|title=200 CE (M 111 engine) / C 124 E 20/2, 1992 - 1993|website=mercedes-benz-publicarchive.com|access-date=20 November 2023}} is a {{convert|1998|cc|L|1|abbr=on|order=flip}} 16-valve engine with bore and stroke of {{convert|89.9x78.7|mm|2|abbr=on}} and compression ratio of 9.6:1.

Applications:

• 1992–1997 E 200 (W124)

Unlike the 102, 103, and early 104 series engines, the engine did not use mechanical fuel injection but the Siemens PEC/PMS (Pressure Engine Control) management system, which integrates fuel and spark management.

It is a speed-density type of system, as mixture formation is dependent on RPM, TPS angle, and manifold pressure (MAP).

Injectors work in pairs (idle, part load), or altogether (full-load).

It uses 2 ignition coils and no ignition distributor. Cylinders are fired in pairs (dual fire) - 1 and 4 together, and 2 and 3 together. The crankshaft position sensor is sensing the movement of two radially opposed position plates on the flywheel, one of which is magnetized, and the other is not. Thus, the engine management has precise information which group of cylinders to fire, and which group of injectors to spray.

Similar to the M111.940 engine, used in the following years. It produces {{convert|100|kW|PS hp|0|abbr=on}} of power and {{convert|190|Nm|lbft|0|abbr=on}} of torque.{{cite web|url=https://mercedes-benz-publicarchive.com/marsClassic/en/instance/ko/C-200--W-202-E-20-1994---1997.xhtml?oid=5523|title=C 200 / W 202 E 20, 1994 - 1997|website=mercedes-benz-publicarchive.com|access-date=20 November 2023}}

Applications:

M111.941:

• 1993–1996 C 200 (W202)

M111.946:

This motor never had PMS. Early models -95 to -97 has a HFM-motronic, hot-film type air/fuel metering device, and -97 to -2002 with ME2.1 motronic. The later system also has a magnet on the intake camshaft, and gives signal to ECU, to assist the motor in producing more torque at low revs. The early motor didn't have any camshaft position sensor, so wiring was much different.

The only problem experienced with this M111 excellent reliability motor is the originally installed Victor Reinz headgasket, which eventually tore apart by age, and made the top lose coolant on the side. Other than that, only some year models, had bad insulation on the engine wiring, that needed all the wiring to be replaced.

The power is {{convert|95|kW|PS hp|0|abbr=on}}, torque {{convert|180|Nm|lbft|0|abbr=on}} at 4200 rpm.
