Cylinder Head Assembly: Description and Operation

DESCRIPTION





The cast iron cylinder heads (Fig. 7) are mounted to the cylinder block using eight bolts. The spark plugs are located in the peak of the wedge between the valves.

OPERATION
The cylinder head closes the combustion chamber allowing the pistons to compress the air fuel mixture to the correct ratio for ignition. The valves located in the cylinder head open and close to either allow clean air into the combustion chamber or to allow the exhaust gases out, depending on the stroke of the engine.
