Abstract
The object of this invention is that a suction device for an internal combustion engine is to be compact. The suction device comprising a casing having an air inlet and a plurality of outlets, a filter in the casing for filtering air from said air inlet, a collection chamber in the casing for receiving air from the filter, at least one throttle valve in the casing for controlling the flow of air from said filter to said collection chamber, and a plurality of suction pipes. According to the present invention, the suction device can be made compact to thereby effectively use an engine room of an automobile.
