Pengaruh Variasi Turbo Cyclone pada Saluran Udara Masuk Terhadap Unjuk Kerja Mobil Avanza Veloz Tahun 2012

Turbo cyclone is an additional tool used in the engine combustion which serves to change the flow of air in the intake manifold becomes swirl. This study investigated the performance effect of the engine combustion in the form of torque, mean effective pressure, and the power between an engine that do not use turbo cyclone with an engine that utilizes turbo cyclone. In addition, this study has purpose to get a good design of turbo cyclone for engine combustion of gasoline 1500 cc. This study used type of research design. It designed a turbo cyclone with variation in the type of blade and number of blades. This research uses experimental method. This research utilized turbo cyclone that has been made in the design prior to the testing for comparing the performance of engine combustion without turbo cyclone in standard condition with the performance of using turbo cyclone on the air duct before the throttle body. The independent variable of this study is the use of turbo cyclone with 3 types of blade perforated (type B3), turbo cyclone with 6 types of blade perforated (type B6), turbo cyclone with 3 types of blade not perforated (type A3), and turbo cyclone with 6 types of blade not perforated (type A6). While, this research observed the performance of the engine combustion in the form of torque, mean effective pressure, and power as the dependent variable. The result showed that the highest torque is 149,6 Nm at 4000 rpm on the use of turbo cyclone type B3. The result of the highest mean effective pressure is 1288,51 kPa at 4000 rpm. While, performance of highest power in the engine combustion standard without the use of turbo cyclone is 85,79 kW at 6000 rpm. The best design to be applied on the gasoline engine of 1500cc is turbo cyclone type B3. Keywords: Power, Swirl, Turbo Cyclon
