ABSTRACT:
An apparatus for controlling the opening degree of a throttle valve during starting and warming up of an internal combustion engine, has the following constituents: a fast idle cam which operates to progressively decrease the opening degree of the throttle valve as the warming up of the engine proceeds; a starting cam provided separately from the fast idle cam and adapted to maintain a large opening degree of the throttle valve; a first means for bringing, while the engine is not operating, the starting cam into operative position for holding the throttle valve, in response to a throttle opening operation; and a second means for releasing, when a predetermined engine temperature is reached after the starting of the engine, the holding of the throttle valve by the starting cam and insteadly bringing the fast idle cam into operation for controlling the opening degree of the throttle valve.
