N2 - Investigation on the use of biodiesel produced from palm oil and hydrogen gas in diesel engines has been carried out. A single-cylinder diesel engine can be operated directly on palm oil biodiesel, and the manifold is then field with hydrogen at a flows of 2.5, 5, 7.5, and 10 lpm respectively. In this study, a single-cylinder diesel engine with a light load and a constant speed of 2000 rpm is used with a direct injection system. Therefore, this study aims to examine the combustion and performance characteristics of diesel engines, fueled by hydrogen gas and palm biodiesel. The cylinder pressure, the heat release rate, ignition delay, and knocking are explored as aspects of combustion. Additionally, thermal efficiency and fuel consumption are both factors that contribute to overall engine performance. The results at lower load showed that small hydrogen flow produced the lowest ignition delay at Diesel Dual-Fuel (DDF) of BH 2.5 lpm, and the lowest knocking at 10 lpm hydrogen flow. In addition, there was an average 27.38% increase in BTE and an average 47.61% decrease in Specific Fuel Consumption (SFC) compared to biodiesel.
