4. Kesimpulan Mesin diesel satu silinder dijalankan menggunakan limbah biodiesel campuran minyak B10, B20 dan B30. Performa dan emisi gas buang diukur pada beban engine yang berbeda 1, 2, 3 dan 4 kW dan kecepatan engine konstan 1500 rpm. Konsumsi bahan bakar spesifik, efisiensi termal, suhu gas buang, rasio udara- bahan bakar dan efisiensi mekanik diukur. CO, CO2, NOx, HC dan emisi diukur dan dibandingkan dengan bahan bakar diesel. Kesimpulan berikut dapat diringkas sebagai: 1. Efisiensi termal dari campuran biodiesel minyak goreng dengan bahan bakar diesel lebih rendah dibandingkan dengan bahan bakar diesel dan konsumsi bahan bakar spesifik ditemukan lebih tinggi. 2. Suhu gas buang yang lebih tinggi dicatat untuk campuran biodiesel minyak jelantah dibandingkan dengan bahan bakar diesel untuk seluruh beban mesin. Rasio udara-bahan bakar untuk campuran biodiesel-diesel B10, B20 dan B30 lebih rendah dari bahan bakar diesel 3. CO, HC dan emisi lainnya lebih rendah untuk campuran biodiesel minyak goreng dibandingkan dengan bahan bakar diesel. 4 Emisi NOX dan CO2 meningkat dengan meningkatnya persentase bahan bakar biodiesel dalam campuran

Journal 3 Effect of waste cooking-oil biodiesel on performance and exhaust emissions of a diesel engine Abstract The ever increase in global energy demand, consumption of depletable fossil fuels, exhaust emissions and global warming, all these led to search about alternative fuels. Biodiesel was produced from waste cooking-oil by transesterification process. Blends of waste cooking-oil biodiesel and diesel oil were prepared in volume percentages of 10, 20 and 30% as B10, B20 and B30. Biodiesel blends have ASTM standards of physical and chemical characterization near to diesel fuel. Diesel engine performance and exhaust emissions were studied experimentally for burning waste cooking-oil blend with diesel fuel. This experimental was applied on a diesel engine at different engine loads from zero to full load. Thermal efficiencies for waste cooking-oil biodiesel blends were lower than diesel oil. Specific fuel con- sumptions of biodieselblends were higher than diesel fuel. Higher exhaust gas temperatures were recorded for biodiesel blends compared to diesel oil. CO 2 emissions for waste cooking-oil biodiesel blends were higher than diesel oil. CO, smoke opacity and HC emissions for biodiesel blends were lower than diesel fuel. NO x emissions for biodiesel blends were higher than diesel fuel. 1. Introduction Oil crisis and global warming led to the research has been oriented to find suitable alternative fuels to petroleum oil. Now biodiesel was produced from non edible vegetable oils because the high price of edible vegetable oils, it was becoming enviromen- tally an alternative fuel to diesel oils [1] .

Biodiesel and its blends with diesel fuel are investigated to solve the problem of depletion of fossil fuels and environmental impact. Biodiesel; as an alternative fuel for diesel fuel, is methyl or ethyl esters extracted from vegetable oils or animal fats by transesterification process. A diesel

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
