Abstract
A system for regulating the engine speed of an internal combustion engine having a carburetor and a throttle valve in the carburetor. The system comprises an electro-mechanical actuator having a push rod engaged with a throttle lever for maintaining the throttle valve to an open state, a speed sensor for detecting the speed of engine, and an electronic control circuit. The electronic control circuit comprises a comparing circuit connected to the speed sensor, a level setting circuit for applying a standard level to the comparing circuit for comparing the output of the speed sensor with the standard level, and a control circuit for producing a pair of output signals for a time period in dependency on the output of the comparing circuit. Output signals of the control circuit are applied to a driving circuit for driving the electro-mechanical actuator for projecting or retracting the push rod, so that throttle valve is opened or closed in dependency on the output signals of the speed sensor for controlling the engine speed to the standard level.
