A system for regulating the engine speed so as to maintain the voltage between terminals of a battery at a constant value. A constant-voltage circuit is connected at a terminal of the battery for supplying a constant voltage. A comparator is provided for comparing the voltage between the terminals of the battery with the constant voltage and for producing an output signal in dependency on the difference between the input voltages thereto. The output signal is fed to an actuator through a driving circuit. The actuator operates in response to the driving signal from the driving circuit for opening or closing the throttle valve for regulating the engine speed, so that the voltage between the terminals of the battery may be maintained at a constant level.
