Abstract
Two-bank internal-combustion engine, per cylinder bank air intake system has, per cylinder bank, one resonance container and, centered thereto, has another container. By way of suction pipes, the resonance containers are connected to the cylinders and are provided with connecting pipes among one another, with fresh air entering into one of these. Suction pipe extensions are connected to the other containers, and extend partially in the resonance containers while being aligned at a distance with the inflow funnels of the suction pipes. The combination of the connecting pipes acting as a resonance pipe with the suction pipe extensions acting as a ram pipe causes a mean pressure increase, whereby the torque as well as the power of the internal-combustion engine are increased.
