Abstract
A suction system for a combustion air supply to an internal combustion engine, in particular for a motor vehicle, having an induction funnel which at an open end has an induction pipe, and an air manifold, on which cylinder-specific suction pipe arms, which can be connected to a cylinder head of the internal combustion engine, are arranged. In this system, the induction funnel and the air manifold are formed in a common housing. A partition of the housing separates the induction funnel from the air manifold.
Claims6
A suction system for a combustion air supply to an internal combustion engine, comprising:
- an induction funnel having an open end with an induction pipe;
- an air manifold;
- and cylinder-specific suction pipe arms arranged on the air manifold so as to be connectable to a cylinder head of the internal combustion engine, the induction funnel and the air manifold being formed in a common housing, the housing having a partition arranged to separate the induction funnel from the air manifold, a slot being formed in the partition so as to connect the induction funnel to the air manifold, the partition, on a side which extends substantially parallel with respect to at least one of the induction funnel and the air manifold, ending at a predetermined distance from a wall of the housing with a free end which forms the slot, the free end, as seen in cross-section, being formed as a bead.
