Injector(S), Fuel: Operation: Operation
WARNING: This page is about a different car, the 2014 Dodge Journey. However, it is still accessible from the selected car via links, so may be relevant.
The Common Rail system makes it possible to carry out a pre-injection (pilot injection) before T.D.C. This has the advantage of reducing the pressure shift in the combustion chamber, thus reducing the combustion noise typical of direct injection engines. The control unit controls the quantity of fuel injected, regulating the line pressure and injection times.
The control unit processes the following information in order to control the quantity of fuel to inject:
- Engine RPM;
- Coolant Temperature;
- Turbocharging Pressure;
- Air Temperature;
- Aspirated Air Quantity;
- Battery Voltage;
- Diesel Pressure;
- Accelerator Pedal Position.
