Air intake system of an internal combustion engine

摘要

The air intake system of a double-bank internal combustion engine has one resonance vessel per cylinder bank and a further vessel arranged centrally thereto. The resonance vessels are connected by intake pipes to the cylinders and interconnected by connecting pipes, fresh air entering one of these. Intake pipe extensions, which partially run in the resonance vessels and in the said vessels are arranged at an interval aligning with the input funnels of the intake pipes, are connected to the further vessel. The combination of the connecting pipes acting as resonance pipes with the intake pipe extensions acting as ram pipes causes a mean pressure increase as a result of which the torque and the power output of the internal combustion engine are increased.
