Pengaruh Pemanasan Bahan Bakar dan Penambahan Biodiesel Pada Solar terhadap Konsumsi Bahan Bakar Mesin Diesel Mitsubishi L300

Sari

The purpose of this research is to investigate effect of biodiesel adding into diesel fuel and effect of fuel heating through spiral-fin pipes in the radiator upper tank towards Mitsubishi L300 Diesel Engine fuel consumption. This research was a descriptive quantitative with experiments methods. Sample on this research was a Mitsubishi 4 cylinder type L300 Diesel Engine. Data was getting from measuring Mitsubishi L300 Diesel Engine fuel consumption with the 0 %, 5%, 10%, 15%, 20%, 25% and 30% of biodiesel mix variations, it was included with without heating variations; non-fin pipes heating; and finned pipes heating with inter fin variation was 2 spiral thread, 4 spiral thread, 6 spiral thread, and perpendicular-fin. Result of this research shows as: (1) It has an effect of biodiesel adding into diesel fuel on the Mitsubishi L300 Diesel Engine.; (2) It has an effect of fuel heating using spiral-fin pipes in the upper tank radiator on reducing Mitsubishi L300 Diesel Engine fuel consumption.; (3) It has an effect of biodiesel adding and fuel heating on reducing fule consumption in the Mitsubishi L300 Diesel Engine. The biggest reducing of fuel consumption happens on 20% biodiesel : 80% fuel diesel fuel level and fuel heating using pipes with 6 spiral thread inter-fin variation that is as much as 9.331 ml/minute every cycle. Consumption reducing is 1.320 ml/minute ar as much as 12.393% from standart consumption.
