Cylinder Head Assembly: Description and Operation

7. Cylinder Head
- The cylinder head is made from aluminum die casting.
- Combustion chamber in the cylinder head is a compact, pentroof design and spark plug is located at the center of combustion chamber which feature a wide "squish" area for increased combustion efficiency.
- Four valves (two intake and two exhaust), which are arranged in a cross-flow design, are used per cylinder.
- The cylinder head gasket is a metallic one consisting of three layers of the stainless steel sheets. It has better heat resistance and gas sealability and higher reliability.
- The inner side of grommets used in the cylinder bore are reinforced with wire to withstand both high combustion pressure and temperature.
