Frequently asked questions

The supply pump draws fuel from the tank and pumps it at high pressure to the rail. The quantity of fuel discharged is controlled by the SCV, which is regulated by the ECU.

The engine ECU receives signals from various sensors and uses them to calculate and control the injection quantity, timing, pressure, and EGR. It sends signals to the actuators, such as the injectors and SCV, to achieve optimal engine operation.

The key sensors include the crankshaft position sensor, cylinder recognition sensor, fuel temperature sensor, rail pressure sensor, and others. These sensors detect engine and driving conditions, sending signals to the ECU for processing and control.
