ABSTRACT:
An apparatus for controlling a multi-cylinder type internal combustion engine including first and second cylinder groups each includinhg at least one cylinder. The apparatus comprises sensors for generating electrical signals indicative of engine operating conditions including engine speed, and a control circuit coupled to the sensors for determining an appropriate value repetitively at uniform intervals. This calculation is made according to the engine operating conditions. A fuel supply device is coupled to the control circuit for supplying fuel to the first and second cylinder groups in an amount corresponding to the calculated value. The control circuit operates the fuel supply device to alternatively terminate the fuel delivery to the first cylinder group and the fuel delivery to the second cylinder group under an overspeed condition.
