Control system for alkaline electrolyser focused to enrichment of dual fuel
Keywords:alkaline electrolyser, dual fuel, control
Internal combustion engine vehicles are a key factor in the actual economy and is expected to continue the growth in demand for vehicles using gasoline. Gasoline, like other fossil fuels, is a non-renewable resource whose reserves are constantly declining. Due to this reason, to improve the efficiency and to reduce emissions is of great importance for energy reserves and environmental protection. There are vehicles with hybrid systems and other technologies that reduce fuel consumption and pollutants generation, however most of the vehicles do not have or they are not compatible with the new technologies. This work proposes to enrich gasoline by adding hydrogen to the mixture of fuel and oxygen in order to improve combustion and reduce pollutants. Hydrogen is regarded as a promising alternative fuel for internal combustion engines, which unlike fossil fuels, it can be generated by renewable energy. On the internet there is a set of experiments with alkaline electrolyser, generating oxyhydrogen for fuel enrichment. However, the design and development of a control system, specifically designed for the dynamic performanceof an electrolyser, is not commonly found in the scientific literature. The main approach of this paper is to design and build a power conditioning stage based on synchronous buck converter
is used to provide supply power to an alkaline electrolyzer that produces hydrogen and oxygen with up to 99 % purify.
