The current scarcity of fossil fuels requires the use of alternative fuels in motor fuels, especially diesel engines and gasoline engines. One of the alternative fuels used in plant-based internal combustion engines is biodiesel fuel produced from palm oil. A comprehensive analysis is needed with the use of crude palm oil (CPO) biodiesel fuel because it still causes decreased diesel engine performances. The purpose of this study was to determine the impact of using crude palm oil biodiesel fuel on performance of diesel engine. The research method was carried out experimentally on a diesel engine by comparing the performance of engines using pure biodiesel (B100) and biodiesel (B30) fuels from CPO fuel and compared with diesel fuel (B0) as a control parameter tested by varying the engine loads. The results showed that pure biodiesel fuel (B100) can be used in diesel engines, especially in biodiesel fuel (B30) even though the engine performance is still below diesel fuel (B0). This is marked by the power of 4.24 kW and torque of 19.83 Nm at a high engine load. The use of biodiesel fuel also causes reduced thermal efficiency and increased specific fuel consumption (SFC). © Published under licence by IOP Publishing Ltd.
