Engine Structure (03.01)

Knock Sensors

Two knock sensors are fitted to the cylinder block on the
inboard side of each cylinder bank. The electrical connector
of each sensor is secured to the left-hand engine cover
bracket.
These piezo-electric sensors provide inputs to the ECM to
indicate the detection and location of detonation during
combustion.

Bedplate

This is a structural casting bolted to the bottom of the
cylinder block to retain the crankshaft and to further
improve overall rigidity.
Main bearing clearance changes due to expansion are
minimized by means of iron inserts cast into the bedplate
main bearing supports.
Two hollow dowels align the bedplate with the cylinder
block and the joint is sealed by a continuous bead of sealant.
