ABSTRACT:
In a method of supplying fuel to an internal combustion engine during start-up, the occurence of combustion is detected to arrest the change of the fuel supply quantity until steady-state engine operation is achieved. Combustion is detected by comparing sensed engine speed to a minimum engine speed resulting from combustion in the cylinders. Additionally, control values used to derive the start-up fuel quantity are modified so that the fuel quantity increases monotonically from a relatively low initial value until fuel ignition is detected.
