Fuel Charging And Controls: Overview
WARNING: This page is about a different car, the 2019 Jaguar XE. However, it is still accessible from the selected car via links, so may be relevant.
The fuel charging and controls system is a Direct Injection (DI) system controlled by the ECM (Engine Control Module).
The fuel charging and control system consists of:
- Low Pressure (LP) and High Pressure (HP) Fuel Lines.
- Two HP Fuel pumps.
- Two HP Fuel rails and a crossover tube.
- A Fuel Rail Pressure and Temperature (FRPT) Sensor.
- Six 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 the HP fuel pumps to inject the required volume of fuel into the combustion chambers.
