Abstract

Although the technology of fuel injection in motorcycles has reached ports and direct injection, motorcycles with carburetors are still used. In this research, the carburetor was modified by adding a swirling vane. This study is intended to provide an explanation regarding engine performance which includes torque, power, mileage, emissions, and engine oil temperature. The study begins with a review of the shape and flow characteristics of the swirling vane based on the largest flow according to previous studies. Then, a swirling vane is built and tested to ensure its optimal shape. The findings were compared with conventional carburetor-based engines that had not been treated. Experiments were also carried out on gasoline-ethanol to obtain optimal results and use them appropriately for alternative fuel applications. A comparison of data on torque, power, exhaust emissions, temperature, and mileage reveals that vehicles modified with swirling vanes have better performance. Furthermore, based on the results of gasoline-ethanol application tests, this design is only suitable for use up to E25.
