ABSTRACT
Petroleum is the main source of energy and a source of foreign exchange for the country. However, Indonesia's oil reserves are limited, so alternative fuels are needed. Biodiesel is an alternative fuel to replace diesel which is produced from vegetable oil through a transesterification reaction process between vegetable oil, methanol and a catalyst. However, in its use in diesel engines there is a decrease in engine performance. Several ways that can be used to improve engine performance in using biodiesel include adjusting the injection pressure and increasing the fuel intake temperature. This study aims to determine the effect of adding injection pressure and fuel intake temperature on diesel motor performance such as power, thermal efficiency, sfc, and AFR using biodiesel B40. This study used a single cylinder diesel motor with constant rotation, using 5 variations of injection pressure of 110-150 bar with interval 10 bar, and 5 variations of the intake fuel temperature of 30˚C-70˚C with interval 10˚C and 5 load of 5,000 kg/m2 to 25,000 kg/m2 at intervals of 5,000 kg/m2. Testing and data processing with taguchi method. The results showed that the best performance diesel engine was obtained at an injection pressure of 150 bar and a fuel temperature of 60˚C. Temperature is considered as the most influential factor after load. Predicted performance values achieved under optimal conditions are power was 2.9 kW at a load of 25,000 kg/m2, thermal efficiency was 69.92% at a load of 25,000 kg/m2, sfc was 3x10-5 kg/kJ at a load of 25,000 kg/m2, and AFR was 169.23 at a load of 5,000 kg/m2.
