Engine - V6 S/C 3.0L Petrol (G2289296): Overview: Notes

The V6 3.0L Super Charged (SC) petrol engine is a liquid cooled V6 unit featuring Direct Injection (DI), 4 overhead camshafts and 4 valves for each cylinder.

The main structural components of the engine are all manufactured from aluminum alloy. The engine is built around a stiff, lightweight, enclosed 'Vee', deep skirt cylinder block. A structural windage tray is bolted to the bottom of the cylinder block to further improve the block stiffness. This minimizes Noise, Vibration and Harshness (NVH) and reduces oil foaming. To further enhance the stiffness of the lower engine structure and to reduce engine noise, a ribbed sump body is installed.

The engine uses a High Pressure (HP) Direct Injection (DI) fuel system with fuel pressure provided by 2 HP mechanical fuel pumps. Both fuel pumps are driven by a dedicated camshaft located in the oil pan.

The 4 camshafts incorporate Variable Camshaft Timing (VCT). 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 Camshaft Position (CMP) sensors.

The supercharger (SC) is located in the 'vee' of the engine and is driven from the crankshaft by a dedicated secondary drive belt.

The engine meets EU6 emission regulations in Europe and Rest of World (ROW) and Ultra-Low-Emission Vehicle (ULEV) 70 emission regulations in North American Specification (NAS) markets.

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

Various engine systems are located on the engine assembly and driven directly and indirectly by the engine operation. Refer to relevant article for the further information:
