For controlling the purge quantity the purge control valve is actuated at the ground side by the ME-SFI control unit by means of a pulse width-modulated signal. The purge quantity is determined by constantly opening and closing the purge control valve for on and off periods of various lengths.
The frequency of the pulse width modulation signal is selected from a speed-dependent characteristic in such a way, that all cylinders are uniformly supplied with fuel vapors.
The purge control valve is actuated when the engine is at operating temperature, but not in the deceleration mode.
The following information is processed in the ME-SFI control unit:
- Engine speed
- Air mass (boost pressure in supercharged engines)
- Coolant temperature
- Intake air temperature (charge air temperature in supercharged engines)
