Fuel Charging And Controls - INGENIUM I6 3.0L Petrol (G2341935): Overview

WARNING: This page is about a different variant/trim than selected.

The Ingenium I6 3.0L Petrol engine is equipped with a HP Direct Injection (DI) system, controlled by the Powertrain Control Module (PCM). A HP fuel pump delivers a uniform level of pressure to the shared fuel rail, which serves all 6 fuel injectors. Pressure is controllable, to the optimum level for smooth operation, up to 250 bar (3, 626 psi). Low Pressure (LP) fuel from the fuel pump in the fuel tank is pressurized by the HP fuel pump and supplied to the fuel injectors through the fuel rail. The PCM controls the fuel injectors and HP fuel pump to inject the required volume of fuel into the combustion chambers.

The fuel charging and controls system consists of the following components:

LP and HP fuel lines
HP fuel pump
Fuel rail
FRPT sensor
The 6 fuel injectors.

The LP fuel system is covered in the Fuel Tank and Lines section.
