The objective of this study is to enhance engine performance and reduce exhaust emissions of a 200 cc motorcycle engine by modifying the intake manifold through the integration of a spiral turbine. The background of this research is the increasing exhaust emissions of motor vehicles which are one of the main causes of air pollution, as well as the low combustion efficiency of conventional motorcycle engines. The literature review shows that the homogeneity of the air and fuel mixture has a significant role in combustion efficiency and engine performance. The spiral turbine is designed to create a swirling airflow that improves the mixing of fuel and air before entering the combustion chamber. The research method used is an experimental study by testing engine performance using the Dyno Test and analyzing exhaust emissions at various engine speed variations. The parameters tested include torque, power, engine efficiency, and exhaust emissions such as CO, HC, and NOx.The results showed that the installation of a spiral turbine with an inclination angle of 40° and 10 blades provided a significant increase in engine torque and power. In addition, vehicle exhaust emissions, particularly CO and HC levels, were successfully minimized. The prospect of this research is the development of a simple and economical technology to improve engine performance while supporting environmentally friendly air pollution reduction efforts.
