Abstract

The invention relates to a reciprocating piston engine, comprising at least one main combustion chamber, which is formed between a piston and a cylinder and which is connected by means of a riser to a pre-chamber having a pre-chamber axis, so that gas-air mixture pushed from the main combustion chamber into the riser by the piston forms a rising flow in the pre-chamber, wherein a gas supply channel separate from the riser opens into the prechamber, and wherein the riser and the gas supply channel are oriented with respect to each other in such a way that gas fed into the pre-chamber by means of the gas supply channel hits the rising flow substantially head-on, wherein the riser runs at an angle from the pre-chamber axis.
