Engine: Description and Operation

All are water-cooled, four-cylinder, in-line engines with four valves per cylinder, twin overhead camshafts and two balance shafts incorporated in the sides of the block. The engines have fuel injection and are of cross-flow type with the inlet valves on one side and the exhaust valves on the other.
The engine is mounted transversely in the car and inclined forwards at an angle of 8°.

The swept volume of 2.0 liters and 2.3 liters helps to develop high torque even at low engine speeds, which is of particular benefit in normal driving conditions.

The balance shafts are designed to overcome vibration and the forces generated by the moving parts of the engine and at the same time reduce the level of unwanted engine noise.
