ABSTRACT:
A system for controlling supply of fuel to a hybrid fuel powered engine during starting. The system has a sensor detecting the alcohol concentration of the fuel, a device for calculating an alcohol correction factor from the detected alcohol concentration, a device for correcting a basic amount of fuel supply in accordance with the alcohol correction factor, a device for increasing or decreasing the factor in increments of a magnitude determined on the basis of the engine coolant temperature once per interval determined on the basis of the engine coolant temperature, and a device for reversing the direction of the increments each time the factor reaches an upper limit value or a lower limit value, whereby the factor is swept over a prescribed range until the engine starts.
