Description And Operation: Overview: Notes

WARNING: This page is about a different car, the 2018 Jaguar XE and 2017 Jaguar XE. However, it is still accessible from the selected car via links, so may be relevant.

The V6 SC (SuperCharged) 3.0L Petrol engine is a liquid cooled V6 unit featuring Direct Injection (DI), four overhead camshafts and four 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 to further improve the block stiffness, minimize Noise, Vibration and Harshness (NVH) and help reduce oil foaming. To further enhance the stiffness of the lower engine structure, a heavily ribbed sump body is installed. The sump body also helps to reduce engine noise.

The engine uses a Bosch High Pressure (HP) DI fuel system with fuel pressure provided by two, cam driven HP pumps which are driven by a dedicated camshaft. Each HP pump supplies a fuel rail which in turn supplies the three injectors for that bank with fuel at a controlled pressure.

The four 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 Bosch 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 auxiliary drive belt.

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

The DI system, advanced piston and combustion chamber design and the SC provide 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 description and operation for further information:
