Analisa Konsumsi Bahan Bakar sebagai Penggerak Motor Bakar Gokart

Abstract

In the highly competitive wold of racing, karting needed a safe , comfortable,and good engine perfomance when driven on the racecourse, Karting was made for automotive means knowledge for the students Engineering Faculty of University of Medan Area Gokart Engines in use is a motorcycle engine generator set engines 4 step Merk 4-stroke, SOHC, Tahun 1998-2005, 150 cc and using dual clutch. Framework in use consists of a main material, with supporters then in welding be one so that gokart. Results of testing the power 100 4-stroke, SOHC the resulting engine using premium fuel with a round (n) = 6000 rpm, voltage, (v) = 550 volt, Strong currents (I) = 4,5 ampere with P = 2911.76 watt.To calculate the engine power/Brake Horse Power (BHP), P generator = 2911.76 watt, Ƞ generator = 0,88, Ƞ kopling = 0,96 (machine elements) with the results = 3446.68 (watt) the result of the calculation shown in the torque produced by the engine in the round 6000 rpm, 6200 rpm, 6500 rpm, 6800 rpm, 7000 rpm using premium fuel, round Putaran (n) = 6000 rpm, Daya (P) = Watt, power. fuel flow (kg/jam) with result = 0. 16997 kg/jam. On the use of premium fuel value Sfc the greatest was obtained at a large round. 6000 rpm big 5837. 36 g/kw.h. Efisiensi Termal Brake (Ƞ b) most % experienced engine when sing premium fuel to raise experience on your lap 6000 rpm Efisiensi Termal Brake (Ƞ b ) 6200 rpm Efisiensi Termal Brake which is derived by %, on lap 6800 rpm big %, rose again on putaran 6800 rpm big % and on lap 7000 rpm big % testing engine fuels absorb fuel for a time oprasional neeeded as much 8.4 kg liter engine 11.366 if the assumed price of a liter of petrol 1 Liter Bensin @ Rp. 6800;.
