Abstract

The widespread reliance on diesel fuel for transportation and industrial applications is causing environmental pollution, showing the need to explore better alternatives. In this context, the use of biodiesel, or in combination with partially hydrogenated biodiesel, presents a potential substitute for conventional diesel fuel. Therefore, this research aimed to investigate the effects of incorporating biodiesel or partially hydrogenated biodiesel into diesel fuel on torque, power, and Specific Fuel Consumption (SFC). The experiments were carried out by incorporating seven mixtures of diesel fuel, varying from 100% to 70%. The results showed that both biodiesel and partially hydrogenated biodiesel improved power, torque, and SFC compared to conventional diesel fuel, across various ratios and engine rotation. The optimal performance of these mixtures was achieved at approximately 2000 rpm (rotation per minute). Additionally, mathematical models were developed to predict torque and power. The models were optimized for use at engine speeds of 2000 rpm and 4000 rpm, with biodiesel concentrations ranging from 10% to 30% in fuel mixture.

Keywords
