Use of hydrogen as a fuel in IC engines has been supported for years, particularly because of it�s high combustion energy and power output; besides the non-toxic emissions.However, the development and research of hydrogen based engines has always been hindered by the issue of production and storage of hydrogen. In the context of our proposed hydrogen powered internal combustion engine, the primary fuel for powering the engine is still gasoline but we are utilising the loss of gasoline generated power by generating a secondary fuel in the form of hydrogen. A thermo-electric generator or a number of thermo-electric generators are employed on the engine exhaust which converts the engine generated heat energy into electric power. This electric power is then used to electrolyze the water to generate hydrogen. The hydrogen produced in the process is fed to engine, by blending it with gasoline supply, to re-use the power, lost in the form of heat from the engine. Modern gasoline engines have a maximum thermal efficiency of about 25% to 30% when used to power a car. In other words, even when the engine is operating at its point of maximum thermal efficiency, of the total heat energy released by the gasoline combustion, about 70-75% is rejected as heat without being turned into useful work. By using thermo-electric generators this power is recycled and used as a power source for carrying the electrolysis of water for the production of HHO gas. This gas is then blended (1-2% by Volume) with the air/fuel mixture and fed to the engine cylinder for combustion. The engine performance parameters (fuel consumption, thermal efficiency, power, etc.) now get enhanced by a significant amount. Also, reduction in amount of unburned hydrocarbons, CO-CO2 emissions, etc., is achieved.
