Cylinder Head Assembly: Description and Operation

DESCRIPTION

Fig.17:

The aluminum cylinder heads (Fig. 17) are designed to create high flow combustion chambers to improve performance, while minimizing the change to the burn rate in the chamber. The cylinder head incorporates the combustion chamber. Two valves per-cylinder are used with inserted valve seats and guides. A Multi-Layer Steel (MLS) type gasket is used between the cylinder head and engine block.

OPERATION
The cylinder head closes the combustion chamber, allowing the pistons to compress the fuel/air mixture for ignition. The valves are actuated by the lobe profiles on the camshaft to open and close at specified duration to either allow clean air in the combustion chamber or the exhaust gases out; depending on the stroke of the engine.
