The usage of alternative fuel for the vehicles needs to be developed inline with the less of world oil back up which comes from unrenewable fossil. In this project, the development is about the usage of the biogas which comes from Jatropha curcas L as dual fuel diesel engine that <br /> <br /> <br /> needs some component modifications to the diesel motor intake manifold, a kind of mixer between air and biogas. This is the first time performance engine testing that using dual fuel diesel engine solar – biogas which comes from Jatropha curcas cakes. <br /> <br /> <br /> The objective of this project it to understand the biogas fuel characteristic toward performance and emission on dual fuel diesel engine. The biogas fuel that is used was coming <br /> <br /> <br /> from Jatropha Curcas L. Diesel motor that is used is Tian Li Diesel Motor one cylinder, 815 cc, 4 (four) strokes, direct syringe type, maximum power 14 Hp on 2,000 rpm and <br /> <br /> <br /> compression ratio 1 : 20. <br /> <br /> <br /> The result of the test was showing that the usage of the biogas fuel could decrease maximum effective power is 6,8% and also decrease maximum thermal efficiency (Et) is <br /> <br /> <br /> 36%. This project also able to press down solar BSFC amount 40,1 % at 1.500 rpm operation, but the specific energy consumption value was increasing. On the other side, the CO, CO2, and HC emission was increasing, while the O2 everage emission decrease 1,29% and opacity was decreasing round about 79%.
