Kajian Performansi Mesin Genset Otto 1 Silinder dengan Bahan Bakar Campuran Premium dan Super Fuel

Abstract

The decreasing availability of fossil fuels led to a variety of ideas how to solve this problem. Super fuel is one of the alternative fuel that can be used in various engine, one of which is a gasoline engine generator sets in 4-stroke. Research done by variation of the lamp and fuel variations . lamp that is used in research is the 100 Watt lamp. The variation of the lamp is 2; 4; 6; 8; 10 and 12. the variations of fuel for the reseacrh is 100% gasoline; 95% gasoline + 5 % super fuel; 90% gasoline + 10% super fuel and 85% gasoline + 15% super fuel . Based on the analysis , it is known that performance a super fuel mixture decreased torque, Specifiic Fuel Consumption (SFC), the thermal efficiency, and Air Fuel Ratio (AFR). But emissions by using a super fuel mixture , can reduced the content of toxic exhaust emissions such as carbon monoxide (CO) and hydrocarbons (HC) . And Residual rate of oxygen (O2) from the super fuel mixture decreased while the rate of carbon dioxide (CO2) have increased compared to 100% gasoline
