Petrol 4-cylinder in-line engines E200, E230 (Mercedes-Benz E-Class W210)

In June 1996, the 2.0-litre 4-cylinder engine was fitted with a new variable valve timing intake camshaft, previously used on other petrol engines. Power and torque remained unchanged, but the improved torque curve provided easier starting, better throttle response and better pulling power.

The 2.3-liter engine was derived from the proven 2.2-liter unit. The increase in displacement was intended to increase torque, not power. Fuel consumption, exhaust emissions, and combustion noise were optimized by increasing the compression ratio to 10.2 units and improving the geometry of the combustion chamber. The 2-liter engine has the same compression ratio and optimized combustion chamber. The E-200 and E-230 engines are equipped with a modernized fuel injection system with HFM engine management system and a scroll-type air flow sensor instead of the previously used P-motronic.
