ABSTRACT:
A method of controlling the fuel supply to an internal combustion engine at acceleration, wherein a quantity of fuel to be supplied to said engine is increased by the use of a accelerating fuel increment set in response to at least the valve opening speed of a throttle valve arranged in an intake passage of the engine. The accelerating fuel increment is set in response to a parameter value representative of engine load as well as to the valve opening speed of the throttle valve, whereby the fuel quantity is increased by an amount optimal for the engine load, to improve accelerability and emission characteristics of the engine.
