General information
The V8 petrol engine is a 4.4-litre, 8-cylinder, closed V-engine with a 90-degree cylinder bank angle, four valves per cylinder and two overhead camshafts. The engine's exhaust emissions comply with the European ECD3 emission standards and the US federal Tier2 Bin 8 legislation.; to limit emissions of harmful substances, the engine uses catalytic converters, an electronic engine management system, forced crankcase ventilation and an exhaust gas recirculation system. The engine cooling system has a small volume and a high coolant consumption. The fuel injection system is controlled by the engine control unit (ECM).
The cylinder block is made of aluminum alloy with cast iron liners. To increase the rigidity of the lower part of the engine, an aluminum support plate is bolted to it. The cylinder heads are made of aluminum alloy with thermoplastic valve covers. The one-piece oil pan is also made of aluminum alloy. Each row of cylinders has its own two-layer stainless steel exhaust manifold. To reduce engine noise, a noise-insulating plastic cover is installed on top of it.
