Numerical Comparison of B20 Biodiesel and Petroleum Diesel in terms of Performance, Combustion, and Emission at Constant Speed

Abstract

To achieve energy efficiency and emission reduction in the shipping sector use of alternative marine fuel is one of the programs implemented. This study on alternative fuels is an active response to increasingly stringent emission regulations and the limited supply of fossil fuels. In addition, an operational feasibility study is an important thing. The method used in this research is computational fluid dynamics to see how the engine performance, combustion, and emissions when using biodiesel B20 at a constant speed of 2200 Rpm compared to when using petroleum diesel. From the results of the numerical comparison study, the use of B20 compared to petroleum diesel, there was an increase in engine performance the level of fuel consumption was higher. The use of B20 causes CO and UHC emissions to decrease while NOx increases compared to petroleum diesel.
