Abstract

Motor vehicles are a means of transport for which the engine from the beginning, both for two-wheel vehicles, as well as for four-wheeled vehicles. The automotive fuel is a machine that is used as a transport mover soon. The automotive fuel is an engine type conversion that converts the chemical energy of the fuel into mechanical energy through the combustion process in the combustion chamber.This research was conducted using the method or approach theoretically and experimentally. The vehicles to be used in this research is the engine of the Toyota Kijang 4K using premium fuel stations, test equipment used in this study is a dynamometer with changes 5° ignition angle, 8°, 10°, 12°, 15° with the variation of the rotation of the motor 1000, 1500, 2000, 3000 rpm. Regarding the position to carry out research at the Center for Professional Training (BLK) Banjarbaru in JL.IR PM Noor 1.5 Km River Ulin Banjarbaru South Kalimantan.Based on the results of the study of variations of the performance of the engine ignition distributor concluded that: the effective torque of 108,85381 Nm, which is contained in the ignition angle 12° with the motor rotation of 3000 rpm, the effective power contained in the corner Ignition of rotation of 3000 rpm 12° reach 34,18021 (Kw) and efektir pressure contained in the ignition angle 12° at 3000 rpm round reached 6387,235(kg/cm²). The increase in torque due to rotation higher up to reach the maximum price, this is because the amount of fuel in the combustion chamber and the greater the influence of the right letikan sparks from the spark plug so that the energy generated through process burn largest.Keywords: ignition angle, torque, Brake Horse Power (BHP), Brake Mean Pressure (BMEP)

Abstract

Penelitian ini bertujuan untuk mengetahui pengaruh kecepatan poros yang optimal menggunakan turbin angin savonius sudu U dengan penambahan sudu NACA 0012 dengan variasi kecepatan angin, untuk turbin angin savonius U memiliki dimensi diameter 12,7 cm dengan tinggi 50 cm dan NACA 0012 tinggi 50 cm dengan lebar 14 cm. Dari hasil penelitian turbin angin menunjukkan bahwa dengan penambahan sudu NACA 0012 berpengaruh terhadap putaran poros, dengan menggunakan variasi kecepatan angin 2,3 m/s, 3,5 m/s, 4,0 m/s, 6,2 m/s, 7,2 m/s, dari data yang di dapat dengan menggunakan penambahan sudu NACA 0012 kecepatan poros tertinggi 132,9 rpm dengan kecepatan angin 7,2 m/s. Dengan penambahan sudu NACA 0012  putaran poros tertinggi 132,9 rpm dengan kecepatan 7,2 m/s dan kecepatan putaran poros terendah 33,2 rpm dengan kecepatan angin 2,3 m/s.Kata Kunci           : Turbin angin, savonius, sudu U, NACA 0012
