Abstract
The admission manifold comprises a plenum chamber (1) downstream from a butterfly valve (2) and defining a resonance volume, an air inlet diffuser (6), an inlet (8) connected to the outlet from the butterfly valve (2), an air flow guide (11), and as many suction ducts (15) as there are cylinders in the engine, each duct feeding a corresponding cylinder thereof. The guide (11) serves to share admission air coming from the diffuser (6) between the ducts (15), and it is mounted downstream from the diffuser (6) in such a manner that the outlet (10) from the diffuser (6) opens out towards the tubular inlet (12) of the guide (11) which has an upstream edge spaced apart transversely from the downstream edge of the diffuser (6) by a permanent diaphragm. The diffuser (6), the guide (11), and at least an upstream portion of each duct (15) are housed inside the plenum (1). The manifold is applicable to feeding air to fuel injection internal combustion engines.
