Abstract

Die Erfindung betrifft eine Kolbenbrennkraftmaschine, die je Zylinder wenigstens einen in wenigstens eine Durchtrittsöffnung (3) ausmündenden Gaseinlaßkanal (4) aufweist, der über zumindest eine Teillänge durch wenigstens eine Trennwand (5) in wenigstens zwei Teilkanäle (4.1 , 4.2) unterteilt ist, die zumindest für einen Teilkanal (4.1;4,2) eine in Strömungsrichtung verlaufende rinnenförmige Profilierung aufweist.

Figure 00000001
The invention relates to a piston internal combustion engine, which has at least one gas inlet channel (4) opening into at least one through opening (3) per cylinder, which is divided over at least a partial length by at least one partition (5) into at least two partial channels (4.1, 4.2), which at least for a sub-channel (4.1; 4.2) has a channel-shaped profile running in the flow direction.
