ABSTRACT:
An internal combustion engine is described in which the shape and construction of the gas outlet end portion of a sub-suction path is made operative to inject a gas such as air, an air-fuel mixture or exhaust gas circumferentially into the combustion chamber during the suction stroke. The gas outlet end portion has a reduced diameter and an injection nozzle which has a length greater than its internal diameter. Moreover, the gas outlet end portion is constructed of a pipe member which is rotatably and adjustably fitted into the insertion hole of a cylinder head and which is so shaped that the open direction of the outlet end thereof can be changed when it is rotationally adjusted.
