Uji Kinerja Bahan Bakar Bensin 92 Ultra Fine Bubble

Abstract

Motor bensin adalah salah satu mesin pembakar dalam atau sering disebut internal combustion engine (mesin yang mengubah energi termal menjadi energi mekanik). Motor bakar bensin ini biasanya banyak sekali digunakan pada bidang pertanian dan transportasi. Bensin 92 merupakan jenis bahan bakar yang memiliki angka oktan 92. Penambahan Ultra Fine Bubble pada bahan bakar bensin 92 berpotensi meningkatkan efektivitas pembakaran pada mesin bensin karena kandungan oksigen yang menjadikan reaksi pembakaran sempurna. Penelitian ini digunakan untuk mengetahui dan membandingkan hasil performa serta emisi gas buang bahan bakar tanpa penambahan Ultra Fine Bubble dengan bahan bakar penambahan Ultra Fine Bubble. Penelitian ini dilakukan dengan metode eksperimen dan uji kinerja. Berdasarkan hasil percobaan UFB 20 menit dan UFB 30 menit menghasilkan konsumsi bahan bakar yang lebih baik dan kadar emisi gas buang menurun. Penurunan emisi gas CO pada UFB 10, UFB 20, dan UFB 30 menit berturut turut adalah 4%, 3%, dan 1%. Penurunan emisi gas HC pada UFB 10, UFB 20, dan UFB 30 menit berturut-turut sebesar 22,5%, 22,5%, 25,8%. Setelah dilakukan pembobotan, perlakuan UFB 30 menit paling efektif daripada perlakuan yang lain.

Gasoline motor is one of the internal combustion engines or often called internal combustion engine (engine that converts thermal energy into mechanical energy). This gasoline motor usually widely used in agriculture and transportation. Gasoline 92 is a type of fuel just has octane number 92. The addition of Ultra Fine Bubble on gasoline 92 has the potential increasing of burning effectivity of gasoline engine. It is due to oxygen content which making combustion reaction more perfect. This research was aimed to determine and compare the engine performance and exhaust emission of fuel for both with and without addition of UFB. The methodology used were experimental methods and performance testing. Based on the results of the experiments, UFB 20 minutes and UFB 30 minutes resulted in better fuel consumption and the levels of exhaust gas emissions decreased. The decrease in CO gas emissions for UFB 10, UFB 20, and UFB 30 minutes were 4%, 3%, and 1%, respectively. The reduction of HC gas emissions at UFB 10, UFB 20, and UFB 30 minutes were 22.5%, 22.5%, and 25.8% respectively. After weighting, the UFB 30 minutes treatment was the most effective compared to the other treatments.
