Abstract

The use of fuel oil to generate heat or power in the industrial world is still a major concern for researchers. Fuel quality, performance, emissions, and economic factors are some of the parameters that need to be considered for various types of fuel. In Indonesia, there are several types of diesel fuel including Pertamina Dex, Dexlite and Biosolar (B30). Of course, these fuels have different characteristics. To be able to know the character of the fuel, it is necessary to test the fuel on a diesel engine. In this study, an experiment was carried out using this fuel in a Jianfa brand diesel engine with a power of 7 HP type R175A without load with various variations of rpm, namely 1000, 1200, 1400, 1600, 1800, 2000, 2200. The experiment applies to three types of fuel, namely Biosolar (B30), Pertamina Dex, and Dexlite. Consumption is measured in units of time (seconds) per 50 milliliters. From the experiments it was found that Biosolar (B30) occupies the lowest position as evidenced by the duration of time to spend 50 milliliter at 2000 rpm only takes 49 seconds, Dexlite 63 seconds while Pertamina Dex 70 seconds. So it can be concluded that Pertamina Dex is the most economical compared to Dexlite and Biosolar (B30).

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.
