Cylinder Heads
NOTE:
RH (A bank) cylinder head shown, LH (B bank) cylinder head similar.
The cylinder heads are manufactured in gravity die cast aluminum alloy and are unique for each cylinder bank. Deep-seated bolts reduce distortion and secure the cylinder heads to the cylinder block.
Each cylinder is served by four valves. To help achieve the required gas-flow characteristics, these are arranged asymmetrically around the cylinder bore. Each cylinder has a centrally mounted fuel injector and spark plug.
The cylinder head gasket is of a multi-layer steel construction.
