Abstract

An arrangement for exhaust gas feedback in a four-stroke combustion engine with at least two cylinders (A, B) cooperating with one another, whereby each cylinder in the engine is connected by a transfer line (8) to another cylinder operating with substantially approximately 360 DEG displacement. Exhaust gas feedback is made possible by using the overpressure prevailing in the respective cylinder (A, B) during its expansion stroke to feed exhaust gases back to the cooperating cylinder during the latter's induction stroke. This is made possible by the fact that the transfer line is provided with controllable valves (8) at both of its respective ends and by the fact that the transfer line leads into the respective cylinders.
