Abstract
A throttle valve is opened upon engine cranking through a predetermined angle by a vacuum-operated valve in response to a vacuum signal supplied thereto from a vacuum pickup port positioned downstream of the throttle valve, for assisting the engine in getting started quickly and stably. A directional control valve is actuated upon engine cranking to allow the vacuum signal to be fed to the vacuum-operated valve. The vacuum pickup port communicates with the vacuum-operated valve through vacuum passages having thermosensitive valves one openable when the engine is kept below a preset temperature and the other openable when the engine temperature is above the preset level. A pressure delay means may be connected between the vacuum pickup port and the vacuum-operated valve to delay closing of the latter after the engine cranking.
