Zusammenfassung:	Herein an internal combustion engine (2) comprising at least one cylinder arrangement (4) forming a combustion chamber (23) is disclosed. The engine (2) further comprises at least one turbine (21) comprising a turbine wheel (26) and having a turbine wheel inlet area, ATIN. An exhaust conduit (6) extends from a port (15) arranged in a lower half of a cylinder bore (12) of the cylinder arrangement (4) to the turbine wheel inlet area, ATIN. The piston (10) has different piston stroke lengths, the power and exhaust strokes being longer than the intake and compression strokes, such that the port (15) is uncovered by the piston (10) during part of the power and exhaust strokes and is covered by the piston (10) during the intake and compression strokes. L'invention concerne un moteur à combustion interne (2) comprenant au moins une disposition des cylindres (4) formant une chambre de combustion (23). Le moteur (2) comprend en outre au moins une turbine (21) comprenant une roue de turbine (26) et ayant une zone d'entrée de roue de turbine, ATIN. Un conduit d'échappement (6) s'étend d'un orifice (15) agencé dans une moitié inférieure d'un alésage de cylindre (12) de la disposition des cylindres (4) à la zone d'entrée de roue de turbine, ATIN. Le piston (10) a différentes longueurs de course de piston, les courses de combustion et d'échappement étant plus longues que les courses d'admission et de compression, de telle sorte que l'orifice (15) est découvert par le piston (10) pendant une partie des courses de combustion et d'échappement et est recouvert par le piston (10) pendant les courses d'admission et de compression.
