ABSTRACT:
A recirculating and recombustion type of exhaust gas purification system for a compression ignition engine includes an expansion manifold 11 communicating with the auxiliary combustion chambers 7 of each cylinder via circulating passages 12 controlled by cam operated valves 13. The relatively rich exhaust gas remaining near the fuel injector 8 in an auxiliary chamber 7 at the end of a power stroke is expanded into the manifold 11 via an open control valve 13, and is then drawn into the auxiliary chamber of another cylinder whose piston is near the bottom of its intake or suction stroke via another open control valve. The thus recirculated or transferred exhaust gas is cooled by its expansion into the manifold, as well as by water jacketing within the cylinder head and air surrounding the exposed periphery of the manifold.
