Engine - V8 S/C 5.0L Petrol (G2318506): Overview: Notes

The V8 5.0L S/C Petrol engine is a liquid cooled, SuperCharged (SC), V8 unit. The engine has Direct Injection (DI), 4 overhead camshafts and 4 valves per cylinder.

The main structural components of the engine are all manufactured from aluminum alloy. The engine is built around a very stiff, lightweight, enclosed V, deep skirt cylinder block. A structural windage tray is bolted to the bottom of the cylinder block. The windage tray improves the block stiffness, minimizes the Noise, Vibration and Harshness (NVH) and helps reduce oil foaming. To further enhance the stiffness of the lower engine structure, a heavily ribbed oil pan is installed. The oil pan also helps to reduce engine noise.

The engine uses a High Pressure (HP) DI fuel system. There are 2 HP fuel pumps which provide the required fuel pressure and are driven by a dedicated camshaft. Each HP fuel pump supplies a fuel rail which in turn supplies the 4 injectors for that bank with fuel at a controlled pressure.

The 4 camshafts incorporate the Variable Camshaft Timing (VCT) system. The VCT allows the timing of the intake and exhaust valves to be adjusted independently of each other. The VCT system is controlled by the Powertrain Control Module (PCM) using information from the 4 Camshaft Position (CMP) sensors.

The supercharger is located in the 'vee' of the engine and is driven from the crankshaft by a supercharger drive belt.

The engine meets the EU6c emission regulations in Europe and Rest of World (ROW) markets. The engine meets ULEV 125 emission regulations in North American Specification (NAS) markets.

The DI system, advanced piston and combustion chamber design and the supercharger provide improved fuel consumption and emissions.

Various engine systems are located on the engine assembly and driven directly and indirectly by the engine operation.
