DESCRIPTION AND OPERATION
DESCRIPTION
The V8i engine has cast aluminium cylinder heads
and cylinder block. The two banks of steel cylinder
liners which are pressed down to stops in the block,
are set at 90
°
to one another. The three ringed
aluminium pistons transmit the power through the
connecting rods to a cast iron five bearing crankshaft,
which drives the centrally located camshaft via a
duplex type chain.
The electronic ignition distributor is driven by a gear
off the front of the camshaft and the lubrication oil
pump is driven by a gear off the front of the
crankshaft. The overhead inlet and exhaust valves are
operated by rocker shafts, pushrods and self adjusting
hydraulic tappets.
Multiport fuel injection ensures that engine
performance, economy and exhaust emissions are
automatically correct for the demands of highway and
off road operation.
