Abstract
A method for controlling the supply of fuel and ignition spark for an internal combustion engine. The supply of fuel which is mixed with air is cut off upon engine deceleration and resumed thereafter. At the transition from the cut-off to resumption of supply of fuel, the timing of ignition spark which ignites the mixture of air and fuel is retarded enough to prevent an abrupt increase in an engine output torque. The retarded timing of ignition spark is then advanced gradually as the time passes so that the engine output torque increases gradually.
