Fuel Charging And Controls - Overview (G1550499): Overview

WARNING: This page is about a different car, the 2015 Jaguar XF, 2014 Jaguar XF, and 2013 Jaguar XF. However, it is still accessible from the selected car via links, so may be relevant.

The GTDi 2.0L PETROL engine is equipped with a high-pressure direct injection system controlled by the ECM (engine control module). A high-pressure fuel pump delivers a uniform level of pressure to the shared fuel rail, which serves all 4 fuel injectors. Pressure is controllable, to the optimum level for smooth operation, up to 150 bar (2175 lbf/in² ).

The fuel charging and controls system consists of:

LP and HP fuel lines.
HP fuel pump
Fuel rail
FRP (fuel rail pressure) sensor
Four fuel injectors.

LP fuel from the pump in the fuel tank is pressurized by the HP fuel pump and supplied to the fuel injectors via the fuel rail. The ECM controls the fuel injectors and HP fuel pump to inject the required volume of fuel into the combustion chambers.

The low pressure fuel system is covered in Fuel Tank and Lines. For additional information, refer to "Description and Operation" in the FUEL TANK AND LINES - GTDI 2.0L PETROL -- XF/X250 article.
