System for improving combustion efficiency

Abstract

A system for improving the combustion efficiency of an internal combustion engine having means for supply fuel and primary air for combustion in said engine and a valve for controlling the flow of at least the primary air into the engine, said system including means for introducing liquid in fine particle or vapour form into the primary air stream and means for drawing air treated by said liquid introducing means into the primary air stream at a position immediately down stream of the primary air controlling valve of the engine together with valve means for controlling the flow of said treated air in response to the level of vacuum produced by said engine whereby the valve means is closed when the engine is idling and is open when the engine is operating at a speed above the idling speed. The valve means is positioned in a line connected to the primary air stream and to a source of the treated air, said valve means being spring loaded to close said line when said engine is operating at idling speed, said valve means being opened by the suction is said line at speeds above the idling speed. The liquid introducing means comprises an air and liquid permeable member in the form of an element of open-pore cellular material having a pore density which facilitates proper air flow through the adequate saturation of said element together with means for introducing liquid into the element and for constraining the air flow through the element to ensure that the air collects an adequate amount of liquid in fine particle or vapour form.
