Abstract

Hasil uji eksperimental menunjukkan penambahan bioetanol pada bahan bakar bensin premium cenderung meningkatkan densitas dan viskositas tetapi menurunkan nilai kalor. Sedangkan unjuk kerja cenderung mengalami peningkatan performa dan terjadi penurunan emisi. Torsi, daya dan bmep tertinggi didapatkan oleh campuran E10 dengan kenaikan masing-masing sebesar 2,40%, 2,94% dan 2,72% dibandingkan dengan premium. Sedangkan konsumsi bahan bakar spesifik (sfc) terendah didapatkan oleh campuran E10 dengan penurunan sebesar 4,14% dibandingkan dengan premium. Karakteristik minyak pelumas untuk bahan bakar E5, E10 dan E15 relatif stabil seperti bahan bakar premium. Pencampuran bioetanol pada premium cenderung menurunkan suhu operasional mesin, yaitu mencapai 3,02% pada campuaran 15%. Untuk visualisasi ruang bakar pemakaian bahan bakar E5, E10 dan E15 menghasilkan pengotoran relatif lebih tipis dibandingkan bahan bakar premium. Secara keseluruhan penambahan bioetanol sampai 15% tidak mengalami perubahan pada kondisi operasional mesin. ================================================================================================================== Human dependence on non-renewable energy progressively increasing along with increasing human population. Though the availability of non-renewable energy the longer will be depleted. Therefore the needs for renewable energy development energy today is very important. One of the renewable energy sources are likely to be developed in the country is ethanol. Ethanol has characteristics similar to Premium with a RON value of 108. In this study, we want to know the performance characteristics and exhaust emissions of gasoline engines using fuel with a mixture of ethanol 99.5% premium after durability test during the 5000 KM. In this study also wanted to know the effect of the use of a mixture of ethanol 99.5% with a premium on space fuel and lubricating oil after being used for 5000 KM. Experiment conducted with a durability test car as far as 5,000 km with a fuel mixture of ethanol and gasoline with ethanol mixture variation of 5%, 10% and 15%, measurements covering the content of lubricating oils and visualization of the combustion chamber. Further testing performed at the Laboratory of Combustion and Fuels Engineering Department of Mechanical Engineering FTI-ITS using four-stroke gasoline engine Toyota Vios with a mixture of ethanol variation of 5%, 10%, and 15% with 3000 engine rev up to 6000 rpm. Measurements include torque, power, fuel consumption time, T oil, radiator T, and T and the exhaust gas emissions of HC, CO and CO2. Experimental test results showed the addition of fuel bioethanol in gasoline tends to increase the density and viscosity, but decrease in calorific value. Meanwhile, the performance tends to increase performance and decrease emissions. Torque, power and highest BMEP obtained by a mixture of E10 with each increment of 2.40%, 2.94% and 2.72% compared to the premium. While the specific fuel consumption (sfc) Lowest obtained by a mixture of E10 with a decrease of 4.14% compared to the premium. Characteristics of lubricating oil to fuel E5, E10 and E15 are relatively stable as premium fuel. Mixing bioethanol at a premium tends to lower the operating temperature of the engine, which reached 3.02% in campuaran 15%. For visualization of the combustion chamber fuel E5, E10 and E15 generate fouling relatively thinner than premium fuel. Overall the addition of bioethanol to 15% no change in the operational condition of the engine.
