Abstract

Internal combustion engine with a cylinder block (1) which is formed with an evacuation channel (9, 10) for each cylinder. The respective channels have an end which opens into the cylinder barrel (2) and which is so adapted to the piston (3) that the opening of the channel is exposed when the piston is at its lower dead centre. The channel's opposite end opens out into the inlet channel of the cylinder in the cylinder head of the engine. Exhaust gases can re-circulate to the inlet channels of the engine via the evacuation channels. The quantity of exhaust gas is regulated by valve means (18) in the evacuation channels.
