Abstract: A system for increasing the power and efficiency of engines by increasing the oxygen content in the intake manifold supply using a zeolite filtration system. This system converts the air to a higher oxygen content as it flows to the intake manifold in an engine. The practical idea of this is to increase the power of the engine without increasing displacement, while almost completely diminish NOx emissions as well as reducing fuel consumption. In this invention there are three main components: the zeolite filtration oxygen enrichment system, a system for desorbing nitrogen within the filter when the engine is off or idle, and a wastegate for controlling oxygen enrichment or no oxygen enrichment.
