Diesel 4-cylinder engines: the E 220 D, E 200 CDI and E 220 CDI

Even the smallest model of the new generation of diesel engines Mercedes - released in 1993, a 2.2-liter 4-cylinder E 220 D, designated in the domestic market as OM 604, - its characteristics is an achievement of modern Motors. German manufacturers first began serial production of the 4-valve cylinder head for a pre-chamber diesel engine. Located almost vertically actuated valves located on top of the two camshafts. And the chain drive connected to the crankshaft exhaust camshaft with his hand through the pinion drives the intake camshaft. To achieve a good torque absorption system is a relatively long twin pipes. Moreover, the first time in a diesel engine were used a system similar to a fuel injection system with an electronically controlled gasoline engine (in the diesel engine OM 604 - a system with a distribution fuel pump) and CAN-bus (CAN - Controller Area Network - Switched Data Bus). CAN-Bus makes it possible by changing the output of the motor to carry out the interaction between the group and of the electronic control units of the car, such as a system ASR (traction control), anti-lock braking system ABS, automatic transmission and control system readiness.

If you compare the power characteristics of the 4-cylinder diesel engine with 115 W (/ 8) 60-70th., You can see a huge difference. If the previous 220 D had a capacity of 44 kW / 60 hp at a frequency of engine speed of 4200 ^min-1, the new engine with the same cylinder capacity is 70 kW / 95 hp at a frequency of 5000 min ^-1.

Model E 200 CDI and E 220 CDI, having a power of 75 kW / 102 hp and 93 kW / 125 hp respectively, since June 1998 replaced the 4-cylinder diesel engine with pre-chamber principle.

June 1999 Model E 200 CDI and 220 CDI have been modified significantly increased their power: 85 kW / 116 hp - At the E 200 CDI and 105 kW / 143 hp - At 220 CDI
