Abstract

Biodiesel fuel is a mixture of diesel oil mixed with vegetable oil (palm). The composition of the mixture affects its properties, especially viscosity and density. The research was conducted to determine the effect of increasing temperature on these properties. By applying several experimental methods, including the ASTM D 445-95 method, the pycnometer method, and the particulate emission test method. The biodiesel test was carried out with variations in temperature of 30oC, 40oC, 50oC, 60oC, and 70oC at room conditions of 24.0oC temperature and 71% humidity. From the temperature variation, the viscosity is 2.23 cSt, 2.61 cSt, 3.1 cSt, 3.7 cSt, and 4.45 cSt. The results of the research prove that the increase in biodiesel temperature affects decreasing viscosity and density which has an impact on reducing particulate emissions.

Abstract

Along with advancements in mechanical engineering technology for fishing vessel, particularly in diesel engines, numerous developments have been made to achieve maximum performance. This study aims to determine the effect of applying an exhaust gas recirculation (EGR) system on the performance of diesel engines using B40 biodiesel fuel. The use of biodiesel as an alternative fuel is growing because it can reduce dependence on fossil fuels and reduce exhaust emissions. However, the use of high-blend biodiesel such as B40 can affect combustion characteristics and engine performance. Therefore, a method is needed to optimize engine performance, one of which is through the application of an EGR system. The research method was conducted experimentally by testing diesel engines using B40 biodiesel fuel. The testing was carried out directly by operating diesel engines equipped with EGR systems. The parameters observed included engine performance, such as power and specific fuel consumption. Data was collected under varying load conditions. The data obtained was then analyzed to determine the effect of EGR on engine performance improvement. The results indicate that the application of an exhaust gas recirculation system in diesel engines utilizing B40 biodiesel fuel can influence the combustion process, thereby affecting engine performance. At a valve opening of 25%, the best SFOC can be achieved. The results showed that the application of an exhaust gas recirculation system in diesel engines using B40 biodiesel fuel can affect the combustion process, thereby impacting engine performance. Based on the test results, it can be concluded that the application of an exhaust gas recirculation (EGR) system in diesel engines fueled by B40 biodiesel improves engine efficiency.
