ABSTRACT:
Disclosed is a fuel supply control system for controlling fuel amount to be supplied to an internal combustion engine including a sensor means for detecting engine load condition and other control parameters and generating sensor signals, an arithmetic means for determining a basic pulse width of a pulse signal indicative of basic fuel amount to be supplied, a means for correcting the basic pulse width of the pulse signal corresponding to various control parameter respectively indicative of engine conditions such as engine coolant temperature and a means for distinguishing engine driving condition based on inputs one of which is sensor signal indicative of engine load condition and generating correction command indicative of correction coefficient. The correction command is applied to the correction means to effect the same to increase or decrease the pulse width of the pulse signal or shut off the fuel supply to the engine.
