Cylinder Head Assembly: Description and Operation

Cylinder head
The cylinder head, a light alloy casting, is bolted to the cylinder block. The combustion chambers are hemispherical with 4 valves per cylinder. This design improves the flow of gases in the cylinders, ensuring effective combustion of the fuel-air mixture and so higher efficiency

Timing cover and end plate
The timing cover incorporates the oil pump. The timing cover and end plate are both sealed to the block by means of Loctite 518.
