ABSTRACT:
An air distributor including a cylindrical tubular body including connecting channels supplying cylinders of an internal combustion engine, branches of which open in an aligned manner along a generatrix of the tubular body. The tubular body extends upstream into branches of a 180° elbow that opens at an air inlet, the elbow being inclined in relation to the diametral plane of the tubular body containing generatrix. The distributor includes a ramp partially throttling an air flow area of the main body to reduce a drop in swirl in the first distributed cylinder induced by the inclined elbow distributor, the ramp provided upstream close to the connecting channels branches of the first distributed cylinder on the elbow inclination side. The ramp can have gently- and steeply-inclined upstream and downstream faces. The distributor can mount to an intake face of a diesel engine cylinder head with two intake ducts per cylinder.
