Pollution minimizing device for internal combustion engines

Abstract

Abstract The inlet opening of a chamber is connected to the exhaust manifold of an internal combustion engine so that the combustion products pass through the chamber to an exit opening. The chamber contains a pair of baskets which are open at their upstream ends and closed at their downstream ends. The sides of the baskets are made up of thin copper wire strands placed side by side. The exhaust from the engine is brought into the first basket and the pulses of pressure from the engine exhaust bows the wires outward in a pulsating manner to alternately open and close the spaces between the wires allowing the gases to pass through the spaces. Atmospheric air is introduced into the first basket to mix with the combustion products. The gases emanating from the first basket are introduced into the open end of the second basket and pass through the walls of the second basket in the same manner as the first basket, and then on to the exhaust opening. A feedback conduit leading from the area between the two baskets is brought to the carburetor to feed a minor part of the products within the chamber to the carburetor air inlet opening. Blue sparks are provided at the region of the chamber between the two baskets and also at the carburetor inlet opening. The effect of the small pieces or finely divided copper and the sparks is to produce chemical reactions which result in nearly eliminating from the exhaust opening from the chamber, unburned hydrocarbons, nitrogen oxides and carbon monoxide.
