ABSTRACT:
An internal-combustion spark-ignition V-8 piston engine has an exhaust gas reaction chamber body positioned between its two banks of cylinders. Each cylinder has a main combustion chamber communicating with an auxiliary combustion chamber by means of a torch opening. A main intake manifold with branching portion over the reaction chamber communicates with main intake passages to supply a lean air-fuel mixture to the main combustion chambers. An auxiliary intake manifold with branching portion directly below the central portion of the branching portion of the main intake manifold communicates with auxiliary intake passages to supply a rich air-fuel mixture to the auxiliary combustion chambers. Exhaust passages supply hot exhaust gases from the cylinders to exhaust gas conduits, each of which receives hot exhaust gases from two adjacent cylinders and projects through an insulated wall of the reaction chamber to discharge into it toward an end wall thereof. An exhaust pipe extends through a remote end wall at the opposite end of the reaction chamber. The top wall of the reaction chamber has an exhaust nozzle formed therein facing the branching portion of the auxiliary intake manifold. Also, the top wall of the reaction chamber has a layer of insulation within it and an opening formed to face both of the branching portions of the main and auxiliary intake manifolds. Within the peripheral wall of the exhaust gas reaction chamber body is formed an annular cooling water jacket, and a heat shielding plate covers the outer bottom portion of this exhaust gas reaction chamber body.
