Abstract: This invention is a electronic and mechanical system that comprises of several sub-systems which carries out a new method of using different concentrations of self-propelled hydrogen peroxide-based solutions for direct propulsion in engines designed to use only gas pressure as energy or the system may act as a fuel supplement in existing combustion engines, by manipulating existing oil-based fuel engine's sensor signals to give the system the ability to make the engine run much leaner conditions, or inject less fuel while simultaneously injecting varying concentrations of hydrogen peroxide/water/alcohol solution, consequently saving gas by lowering intake temperatures to reduce the occurrence of knock and exploiting this reduction in temperature by reducing the amount of fuel needed by the engine at all engine running ranges.
