The principle of ECM under different conditions

When the ignition ECU includes elektrobenzonasos that creates fuel pressure in the fuel rail. At the same time, the computer processes the signal from the coolant temperature sensor to determine the necessary duration of the pulses for starting the injection. When the crankshaft of the engine during start-up begins to rotate, the computer generates a pulse inclusion nozzles, the duration of which depends on the temperature of the coolant.
When starting a cold engine injection impulse is increased, the injector open for a longer period of time and the amount of fuel injected more (get more rich fuel mixture).
When starting a warm engine control unit received information on the coolant temperature, gives a command to close the valve set of stabilization of idling, as a result of the injection pulse duration decreases and the opening of the nozzles is reduced to nominal.
At idle information in the computer comes from the throttle potentiometer located in the throttle body and the MAF sensor. By reducing the rotational speed is changed and the ignition timing of fuel injection pulse width is increased, thereby increasing the amount of injected fuel.
During normal operation of the engine throttle position and passing through the air flowmeter the amount of intake air is determined and the duration of opening of the injectors thereby engine operation.
