Cylinder Heads
WARNING: This page is about a different car, the 2013 Jaguar XJ, 2012 Jaguar XJ, 2011 Jaguar XJ, and 2010 Jaguar XJ. However, it is still accessible from the selected car via links, so may be relevant.
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.
