The impact of adding hydrogen on the performance of a CI engine fueled by palm biodiesel

Compression ignition engines are utilized extensively in the support of human life, such as in agriculture and transportation. Diverse factors, such as dwindling oil sources and the environmental impact of diesel fuel as a compression engine fuel, necessitate those researchers seek alternate fuels to lessen reliance on fossil oil. Palm oil biodiesel is the alternative fuel to diesel fuel, which is widely utilized in Indonesia. In addition, hydrogen gas can be used in compression engines as a supplement to fossil fuels. In this study, the effect of hydrogen enrichment on palm biodiesel (B100) combustion in compression ignition engines was investigated. The research was conducted on a single-cylinder diesel engine with constant speed and load. The purpose of this investigation was to evaluate the performance and exhaust emissions of dual-fuel diesel engines. At 50% medium load, the findings of this investigation indicate an improvement in thermal and power efficiency of 65% and 0.8%, respectively, as well as an 82% reduction in fuel consumption compared to biodiesel fuel. The addition of hydrogen gas has a good effect on lowering smoke and NO emissions, while boosting EGT emissions.
