Abstract
A throttle valve actuating system in an electronic control fuel injection system for a spark ignition internal combustion engine which controls air flow rate as a function of fuel flow rate, wherein a throttle valve is made to be able to be opened and closed by a throttle actuator and pneumatic actuator in order to reduce the electric power consumption and to avoid the actuation delay with the variations of the operating conditions and environmental conditions. The throttle valve is operated by such a separate actuating power source as a step motor or the like without directly connecting the throttle valve to an accelerator pedal.
