ANTI-POLLUTION SYSTEM FOR INTERNAL COMBUSTION ENGINES

摘要

A system is presented for use with any internal combustion engine to eliminate carbon monoxide, hydrocarbons and nitrogen oxides from the engine exhaust. The system is substantially closed, eliminating the use of ambient air for combustion of the fuel, and in place thereof utilizes oxygen generated by the thermal decomposition of an alkali metal perchlorate salt in the presence of a catalyst. Heat for the generation of oxygen is provided by the exhaust from the engine manifold. The exhaust and oxygen are then mixed in proportions of 4:1, and the mixture blended with the fuel in the carburetor for combustion in the engine.
