Addition of Oxyhydrogen Fuel to Reduce Hydrocarbon Emissions and Improve Gasoline Engine Performance

Abstract

The threat of global warming is very real before our eyes due to the increasing production of carbon emissions from the use of fossil fuels. Therefore, the use of fossil fuels, especially in the transportation sector, must be stopped immediately and replaced with alternative fuels that are more environmentally friendly. This research aims to apply oxyhydrogen fuel to motorcycles used daily to improve engine performance and reduce hydrocarbon gas emissions in the atmosphere. The test engine used is a 150 cc single-cylinder spark ignition engine. The engine speed varied from 4000 to 8000 rpm, while other parameters were left at standard conditions. The results of engine testing with the addition of oxyhydrogen fuel will be compared with the combustion of gasoline fuel. The results show that all engine performance parameters, including torque, power, and thermal efficiency, increased by an average of 7.65 %. However, the specific fuel consumption decreased by 38.5 kg/(kW · h). Furthermore, combustion emissions, including CO, HC, and CO₂, decreased by an average of 29 %, with the main contributor being a reduction in HC emissions of 45 %. The tool in this research is adaptable and acceptable for application to existing motorcycles, in addition to its small dimensions, good performance, and relatively cheap in manufacturing
