Abstract

The motorcycle is a two-wheeled vehicle driven by a motor fuel. The motor fuel is a machine converting the thermal energy into the mechanical energy. The power and torque are one of the parameters that maintained in improving the motorcycle performances. One of the appropriate ways that can be generated use of enhancing the power and torque is to upgrade the combustion process by pairing the turbulators in the intake manifold. The pairing aims at producing the air vortex into the combustion chamber. The research finding of power and torque using the dynotest indicated that the turbulator used in the intake manifold at a 25 degree blade-angle decreased the power by 22% and torque by 9%. The use of turbulator in the intake manifold at a 40 degree blade-angle increased the power by 12% and torque by 3%. The use of turbulator in the intake manifold at the 55 degree blade-angle, on the other hand, decreased the power by 9% and the torque by 7%.
