Slotted suction pipe

A canned suction pipe is a component in internal combustion engines .

The canned intake manifold is an improved intake bridge and sits on the fresh air side of a mostly charged gasoline engine . It primarily ensures that all cylinders of the engine are filled evenly .

In the case of conventional intake manifolds , high boost pressure often leads to different levels of filling in the individual cylinders, since the inflowing air tries to take the path of least resistance. In a four-cylinder engine, for example, the mixture in the first cylinder is too lean (too much air, too little gasoline), while in the fourth cylinder the mixture is too rich (too much gasoline, too little air). This leads, for example, to the fact that the first cylinder becomes emaciated earlier and tends to ring more than the second cylinder.

The aim is to achieve as uniform a filling as possible in all cylinders with the same air-petrol mixture ratio and the same mixture mass. This is the job of the canned suction pipe.
