Scheme 15: OVERVIEW

The V8 supercharged petrol engine is a 4.2 liter, 8 cylinder, 90 degrees 'Enclosed' V unit, with 4 valves per cylinder, operated by 2 overhead camshafts per cylinder head. The engine emissions comply with ECD3 (European Commission Directive) and US Federal Tier2 Bin 8 legislative requirements and employs catalytic converters, electronic engine management control and positive crankcase ventilation to limit the emission of pollutants. The cooling system is a low volume, high velocity system. The Engine Control Module (ECM) controls the fuel injection system, the ignition system and the electric throttle. The cylinder block is of aluminium alloy construction with cast iron liners. A cast aluminium bedplate is bolted to the bottom of the block to improve lower structure rigidity. The cylinder heads are cast aluminium with thermo-plastic camshaft covers. The single-piece oil sump is also cast aluminium. The fabricated stainless steel twin skin exhaust manifolds are unique for each cylinder bank. A moulded plastic acoustic cover is fitted over the upper engine to reduce engine-generated noise.
