Abstract: An application for a system and method for generating browns gas (mixture of oxygen and hydrogen) from a direct current power source is disclosed. The browns gas is mixed with fossil fuels such as gasoline, ethanol and diesel before combustion in a combustion engine. In such, the efficiency of the combustion engine is improved while reducing emissions of pollutants. A unique grid arrangement is immersed in an electrolyte for generating browns gas. The grid assembly includes conductive plates that are insulated and interspersed between positively biased plates and negatively biased plates, thereby improving the efficiency of the electrolysis.
