N2 - The negative effects of biodiesel's high viscosity and low calorific value on the combustion of diesel engines are due to these properties. This is inversely proportional to the properties of hydrogen gas, which has three times the calorific value of biodiesel. This study seeks to determine the combustion characteristics of palm oil biodiesel and hydrogen gas-fueled dual-fuel diesel engines. At a constant speed, biodiesel is injected directly into a single-cylinder diesel engine with 80% load. In the meantime, hydrogen gas is injected into the intake manifold at varying flows of 2,5, 5, 7,5, and 10 lpm. The results indicated that the addition of hydrogen gas could enhance the combustion characteristics of biodiesel, resulting in a shorter ignition delay and a 10% decrease in knock value compared to biodiesel at a hydrogen flow rate of 10lpm. According to the study, the use of oil palm bodycells with the addition of hydrogen gas is a promising combination for diesel engines; however, additional research is required to determine the efficacy and exhaust emissions produced by the combustion of biodiesel and hydrogen.
