Abstract (en)
[origin: EP0251159A2] 1. A return conduit for leakage gases from the crankcase of a four-stroke internal-combustion engine into the suction pipes of the cylinders, characterised in that the return conduit (6) is in communication with each suction pipe (3) of a cylinder through an opening (8), wherein the diameters of the openings (8) change, seen in the direction of flow of the leakage gases in the return conduit (6), and the last opening has a substantially larger diameter than the first opening and its direction of exit into the suction pipe is different from that of the first opening.
