The four stroke reciprocating piston internal combustion engine has at least one piston (16) having piston rings and sliding in a cylinder (14), which piston opposite a cylinder head (12) having inlet and exhaust valves defines a working chamber (20) of variable volume. In order to achieve favourable exhaust values whilst avoiding expensive catalytic converter devices, it is proposed that means be provided on the wall (15) of the cylinder (14) which, when the piston (16) is in a position close to the bottom dead centre, connect the working chamber (20) to an exhaust gas collecting chamber (22, 6) for the removal of a proportion of the combustion exhaust gases. In addition it is proposed that means be provided for recirculation of the exhaust gas from the exhaust gas collecting chamber into the working chamber of the internal combustion engine. <IMAGE> |
