12-2-2 DESCRIPTION AND OPERATION
Description
General
The V8 petrol engine is a 4.4 litre, eight cylinder water cooled engine having two banks of four cylinders, arranged at
90 degrees to each other, with four valves per cylinder. The engine emissions comply with ECD3 (European
Commission Directive) and NAS LEV 2 legislative requirements. The engine comprises five main castings - two
cylinder heads, cylinder block, timing cover and the oil sump, all of which are manufactured from aluminium alloy.
Plastic rocker covers are fitted to the cylinder heads and, between the cylinder heads, is a plastic manifold intake
assembly. A plastic moulded acoustic cover is fitted over the upper engine to reduce engine generated noise.
The engine is supported, between cast mounting brackets and the front subframe, on two self-contained hydraulically
damped mounts.
Technical Features
The technical features include:
l Four valves per cylinder
l Single plenum chamber
l Variable Camshaft Control (VCC) system
l Double roller timing chain
l Hydraulic Valve Adjusters (HVA)
l Water Cooled Oil Cooler.
Engine Data
The technical data is detailed below
The cylinders are numbered as follows:
NOTE: Cylinders 4 and 8 are at the rear of the engine

DESCRIPTION AND OPERATION 12-2-3
Crankcase
The crankcase is made from Alusil for markets where the fuel contains a high sulphur content. The cylinder barrels
have a nickel dispersion coating (Nikasil), and are finished by polishing only.
An adaptor plate for the feed and return flexible pipes to the oil filter assembly is fitted to the left side of the crankcase.
A water drain plug is located at the lower LH rear corner to drain coolant from the crankcase.
