ABSTRACT:
The air intake system of a two-bank internal-combustion engine has one resonance receptacle for each cylinder bank and an additional receptacle in the respective center. Via suction pipes, the resonance receptacles are connected to the cylinders and are mutually provided with connecting pipes, fresh air entering into one of these connecting pipes. Suction pipe extensions are connected to the other receptacle which partially extend inside the resonance receptacles and are arranged in them at a distance in an alignment with the admission funnels of the suction pipes. The combination of the connecting pipes acting as resonance pipes and the suction pipe extensions acting as swing pipes causes an increase of the mean pressure which raises the torque as well as the performance of the internal-combustion engine.
