Abstract : A system for improving efficiency and reducing harmful emissions in an internal combustion engine and for allowing the engine to run in oxygen poor environments. An oxidant, such as hydrogen peroxide, is introduced into the induction air stream of the engine. A controller senses the temperature and oxygen level in the exhaust stream of the engine and operates a valve to vary the amount of oxidant introduced to maintain maximum efficiency and minimum emissions. The oxidant provides for near stoichiometric combustion to reduce combustion products and reduce the engine's air requirements. The reduced air requirements allow for operation of the engine in oxygen poor environments, such as operation at high altitudes. Water is added to the oxidant to cool the stoichiometric combustion temperature to prevent excessive engine wear and to further block the formation of oxides of nitrogen.
