SPECIFIC FUEL CONSUMPTION TEST ON DIESEL ENGINE WITH VARIOUS TYPES OF FUEL
Diesel fuel has been used as an energy source, and its consumption level is significantly increasing, which can lead to a problem. To solve it, energy conservation with alternative fuels needs to be done. One is biodiesel with waste cooking oil (WCO) as raw material. This type of biodiesel has a low level of oxidation stability. Therefore, a partial hydrogenation (PH) process must be carried out to improve oxidation stability. This alternative fuel was used in an engine performance test using a chassis dynamometer, including torque and power testing. Then, the specific fuel consumption (SFC) was calculated using the torque and power data. The types of fuel used were diesel fuel (D100), a mixture of 90% diesel fuel with 10% biodiesel v/v (B10), a mixture of 80% diesel fuel with 20% biodiesel v/v (B20), a mixture of 70% diesel fuel with 30% biodiesel v/v (B30), a mixture of 90% diesel fuel with biodiesel PH 10% v/v (PH10), a mixture of 80% diesel fuel with biodiesel PH 20% v/v (PH20), and a mixture of 70% diesel fuel with biodiesel PH 30% v/v (PH30). This test was carried out by varying the engine speed from 1700 to 4200 rpm, where the increment interval was 100 rpm. The test results show that the mixture of fuel diesel + biodiesel PH mostly has better torque, power, and specific fuel consumption results than biodiesel.
