Air distributor for supercharged internal combustion engine, has plenum provided with air inlet and opening in conduits, where two conduits having different geometries such that distances separating inlet from outlets of conduits are equal

摘要

The distributor (40) has a plenum (40A) provided with a fresh air inlet (45), and opening in inlet conduits (41-44), where outlets of the conduits are connected to distinct cylinders (11-14) of an internal combustion engine (1). The conduits (41, 42) have different geometries such that acoustical distances (L1-L4) separating the inlet of the plenum from the outlets of the conduits are equal. The conduit (41) extends along a curves mean line, and the conduit (41) extends along a rectilinear mean line.
