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 gasoline Direct Injection (DI) system controlled by the Powertrain Control Module (PCM).
The fuel charging and controls system consists of:
- Low Pressure (LP) and High Pressure (HP) fuel lines.
- HP fuel pumps.
- fuel rails and a cross-over pipe.
- A Fuel Rail Pressure and Temperature (FRPT) sensor.
- 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 cross-over pipe. The PCM controls the fuel injectors and HP fuel pumps to inject the required volume of fuel into the combustion chambers.
