Fuel Charging And Controls - INGENIUM I4 2.0L Petrol (G2298601): Operation: General

The Powertrain Control Module (PCM) controls the output from the High Pressure (HP) fuel pump to deliver the required volume of fuel at pressures up to 200 bar (2900 psi).

By comparing the fuel temperature information from the Fuel Rail Pressure and Temperature (FRPT) sensor to the data in the maps, the PCM compensate the time the fuel injectors need to be energized to deliver the correct mass of fuel to the combustion chambers.
