KAJIAN EKSPERIMENTAL PENGGUNAAN BAHAN BAKAR BIOSOLAR PADA MESIN DIESEL DUAL FUEL BERBAHAN BAKAR BIOSOLAR DAN CNG

Abstract

Various studies on optimizing fuel for diesel engines has been done and one of them is the combination of the fuel system between oil and gas. One is the design process fuel gas supply system for diesel engines DDF (Dual Fuel) Natural Gas - Biodiesel, on the research amount of diesel fuel which is in fixed supply 100% then added supply of natural gas by 20%. Based on test results, CNG is able to substitute up to 75% Biodiesel needs. This research is the development of research on where to early stages of the overall research on experimental studies fuel use dual fuel in diesel engines. This stage will focus on the design engineering Biodiesel fuel system with fuel supply capacity expected Biodiesel is 80% plus 20% more CNG. The installation process machine DDF is slightly different from the installation of the machine in general because of the process of controlling the machine itself will use a control device automation is expected to set the timing and injection of gas while on the installation Biosolarnya modification of the injector so that consumption Biosolarnya can be reduced until it reaches the level of the composition of the fuel ideal. The results of this study will menghasilakn than levels pencapuran most optimal fuel when measured from the level of engine performance resulting in power, SFC and better thermal efficiency than the use of pure Biodiesel.
