Description And Operation: Introduction
WARNING: This page does not describe the selected car, but rather 10 other vehicles, including the 2015 Jaguar XKR-S, 2015 Jaguar XKR, 2014 Jaguar XKR-S, 2014 Jaguar XKR, and 2013 Jaguar XKR-S. However, it is still accessible from the selected car via links, so may be relevant.
The fuel charging and controls system is a gasoline DI (direct injection) system controlled by the ECM (engine control module).
The fuel charging and controls system consists of:
- LP and HP fuel lines.
- Two HP fuel pumps.
- Two fuel rails and a crossover tube.
- A FRP (fuel rail pressure) sensor.
- Eight fuel injectors.
LP fuel from the pump in the fuel tank is pressurized by the HP fuel pumps and supplied to the fuel injectors via the fuel rails and crossover tube. The ECM controls the fuel injectors and HP fuel pumps to inject the required volume of fuel into the combustion chambers.
