  • Patent number: 10704503
    Abstract: The present invention is related to an optimization method to internal combustion engines that reduces the fuel consumption and the exhaust emissions and particulated material. The operation principle is based in the introduction of small quantities of hydrogen in the air intake duct of the engine with the objective of optimizing the combustion of the traditional fuels, improving the parameters of the combustion reaction. This optimized combustion will increase the efficiency of the engine and reduce its environmental impact. The hydrogen is produced by an electrolysis reaction inside an electrochemical closed cell with non-circulating electrolyte.
