Abstract
Apparatus and method for expediting the starting of an internal combustion engine in which a vacuum-operated throttle actuator is controlled by a vacuum passage connected therewith and extending from an intake vacuum outlet located adjacent to the throttle valve. According to the invention, a second vacuum passage to the actuator communicates with the intake duct downstream of the throttle valve and a solenoid type switching valve is arranged between the two vacuum passages so that, when a warmed engine is restarted, the actuator is fed with vacuum through the second passage to actuate the throttle valve to a more open position than its normal idling position to yield a mixture of optimal air fuel ratio.
