Fuel Injector: Description and Operation

Injector

The injectors inject fuel to cylinders according to the signal, suitable to engine condition, from ECM. The ECM drives the injectors by electric current
driving mode.

The basic fuel amount is performed by the mapping value based on the air amount and engine rate, and the fuel amount is corrected in the case of fuel
amount correction (Air fuel ratio control signal, fuel evaporative emission gas control, learning increase of the fuel amount, warm-up control, catalytic
heating control, fuel amount control in deceleration, idle control, fuel amount increase in full load, fuel increase in acceleration and restarting).

The fuel injection is controlled under unavailable state for safety purpose.
