3.5L Gasoline Turbocharged Direct Injection (GTDI): Notes
WARNING: This page is about a different car, the 2012 Ford Pickup. However, it is still accessible from the selected car via links, so may be relevant.
WARNING:
Do not smoke, carry lighted tobacco or have an open flame of any type when working on or near any fuel-related component. Highly flammable mixtures are always present and may be ignited. Failure to follow these instructions may result in serious personal injury.
The fuel charging and controls system consists of the:
- fuel injectors.
- fuel injection pump.
- Fuel Pump Control Module (FPCM).
- fuel rails.
- Throttle Body (TB).
The fuel charging and controls system is:
- a Gasoline Turbocharged Direct Injection (GTDI) system.
- Pulse Width Modulated (PWM).
Fuel is metered directly into the combustion chamber. Fuel injectors pulse to follow engine firing order, in accordance with engine demand.
The various sensors detect any changes in the operating conditions and send signals to the PCM. This permits the PCM to control the opening duration (pulse width) of the fuel injectors and maintain optimum exhaust emission control and engine performance for all operating conditions.
