Internal combustion engines are used in daily life activities. Fossil fuels are the main fuel used in internal combustion engines because of their increasing consumption, there are concerns that these fuels will be exhausted in the near future. Researchers in the field of internal combustion engines are trying to use alternative fuels to meet the energy needs of internal combustion engines. Among them, hydrogen has attracted attention as an alternative fuel for engines because carbon is not present in hydrogen, so it can burn normally without producing smoke. In this article, hydroxyl (HHO) gas has many excellent combustion properties and can be used to improve the performance characteristics of diesel compression ignition (CI) engines. The electrolysis process using KOH(aq) as a catalyst and stainless steel electrodes in a leak-proof plexiglass reactor to produce brown gas (HHO) is presented in an article in progress. The gas produced was used as a supplementary fuel in the intake manifold of a one-cylinder, air-cooled, four-stroke compression ignition engine test bench (Model #TQ200). The performance characteristics of the engine with and without the HHO generator installed were recorded under the same test conditions. The experimental results were obtained using a hydraulic dynamometer at a constant load condition of 2 Nm of torque over a speed range of 1950 to 3450 rpm. Different engine performance parameters such as engine brake power, brake fuel consumption, thermal efficiency, mechanical efficiency with or without HHO gas and specific fuel consumption were calculated. The results clearly show that the engine brake power, thermal efficiency and mechanical efficiency have been improved by 22%, 47% and 24% respectively, while the engine brake fuel consumption and specific fuel consumption (SFC) have been reduced to a maximum of 35% and 27% respectively, compared to the original engine. The engine was operated without HHO generator. The main goal of this study was to reduce the fuel consumption of the CI engine and increase the power and efficiency, and it was successfully achieved as shown in the results.
