• A lightweight, quenched aluminum alloy with excellent heat conductance has been adopted for the cylinder heads.
• Compact, pentroof shaped combustion chambers have been adopted together with spark plugs positioned at the apex of the combustion chamber to provide improved combustion efficiency.
• The intake/exhaust layout consists of valves set at a 39° parting angle, and two cross-flow type intake and exhaust valves per cylinder for improved intake/exhaust efficiency.

1 | Parting angle between valves
2 | Intake port
3 | Exhaust port

• With the adoption of direct injection, the structure of the cylinder head consists of an injector with an edge that reaches the combustion chamber.
