How electronic fuel injection systems work
1- Open loop system
OPEN LOOP SYSTEM
Only at the moment the vehicle is started, the signal coming from the oxygen sensor is ignored because the vehicle at that moment needs a quantity of fuel in excess of the limit set by the electronic control unit, so the system circuit becomes an open loop.
2-Closed loop system
CLOSED LOOP SYSTEM
After the vehicle engine is running, no signal coming to the electronic control unit from the sensors is ignored; the system circuit becomes a closed loop.
Features of the fuel injection system
The fuel injection system is a precise system when it is controlled by the electronic control unit (computer).
This system has several advantages over the carburetor system, which are:
*Reduced exhaust rate
* Homogeneous mixture in each cylinder
*Achieving the ideal fuel ratio at all different engine speeds.
*Good response compared to the change in the throttle pedal
Improved operation at high temperatures
