EXHAUST PURIFYING SYSTEM FOR MULTI-CYLINDER INTERNAL COMBUSTION ENGINE

摘要

Each cylinder of an internal combustion spark ignition V-8 engine is provided with a main combustion chamber and an auxiliary combustion chamber connected by a torch opening. A lean air-fuel mixture is supplied to the main combustion chambers and a rich air-fuel mixture is supplied to the auxiliary combustion chambers. An exhaust reaction chamber assembly is positioned between the two banks of cylinders and is provided with a liner having a first reaction chamber therein. Four exhaust tubes each connected to receive exhaust gases from two adjacent cylinders project into the reaction chamber and each has a discharge end in close proximity and in substantial alignment with the discharge end of another exhaust tube so that exhaust gases discharged by each exhaust tube enter another exhaust tube and also enter into the first reaction chamber. The first reaction chamber discharges into an enclosing second reaction chamber from which heat is derived to vaporize both of the air-fuel mixtures.
