Abstract
The automotive industry, especially in the motorcycle sector, is experiencing rapid growth where manufacturers compete to market products with attractive aesthetics and superior engine performance. However, motorcycles equipped with an EFI system may experience a decline in performance within two to three years, especially automatic models, which are characterized by slower response and increased vibration. One effective method to improve engine performance is to modify the intake system to optimize air and fuel delivery, thereby increasing power and torque. This research aims to explore the impact of modifications to the intake manifold and throttle body on the engine performance of the Yamaha Mio M3 125cc motorbike. Using a two-level factorial experimental design, this study investigates two main variables: intake manifold diameter (28 mm and 30 mm) and throttle body diameter (26 mm and 28 mm). Tests were carried out using a dynamometer and analyzed using statistical methods. Research shows that modifications to the intake manifold and throttle body significantly affect the performance of the Yamaha Mio M3 125cc engine. The combination of a 28 mm intake manifold and 28 mm throttle body produces the highest torque of 23.1 Nm at around 2000 RPM, while the combination of a 30 mm intake manifold and 28 mm throttle body produces the highest power of 10.97 HP at 6500 RPM. This modification results in an increase in torque of 10.37% and an increase in power of 14.27% compared to standard motor conditions. The air fuel ratio (AFR) produced by modifying the intake manifold and throttle body as a whole shows that Combination 3 and Combination 4 provide better AFR settings at high RPM compared to standard conditions. The best fuel consumption was achieved in combination 3, with the lowest consumption being 140 mL, while the standard motorbike recorded the highest consumption at 250 mL. Other combinations were also more efficient than standard conditions, with consumption varying between 150 mL to 170 mL. Key words: engine performance, throttle body, ported polish, intake manifold, Yamaha Mio M3, injection, fuel efficiency. Industri otomotif, khususnya di sektor sepeda motor, sedang mengalami pertumbuhan yang pesat di mana para produsen bersaing untuk memasarkan produk dengan estetika yang menarik dan performa mesin yang unggul. Namun, sepeda motor yang dilengkapi dengan sistem EFI dapat mengalami penurunan performa dalam waktu dua hingga tiga tahun, terutama pada model otomatis, yang ditandai dengan respons yang lebih lambat dan peningkatan getaran. Salah satu metode yang efektif untuk meningkatkan performa mesin adalah dengan memodifikasi sistem intake untuk mengoptimalkan pengiriman udara dan bahan bakar, sehingga meningkatkan tenaga dan torsi. Penelitian ini bertujuan untuk mengeksplorasi dampak modifikasi intake manifold dan throttle body terhadap performa mesin sepeda motor Yamaha Mio M3 125cc. Dengan menggunakan desain eksperimen faktorial dua tingkat, penelitian ini menyelidiki dua variabel utama: diameter intake manifold (28 mm dan 30 mm) dan diameter throttle body (26 mm dan 28 mm). Pengujian dilakukan dengan menggunakan dynamometer dan dianalisis menggunakan metode statistik. Penelitian menunjukkan bahwa modifikasi pada intake manifold dan throttle body secara signifikan mempengaruhi kinerja mesin Yamaha Mio M3 125cc. Kombinasi intake manifold 28 mm dan throttle body 28 mm menghasilkan torsi tertinggi sebesar 23,1 Nm pada kisaran 2000 RPM, sedangkan kombinasi intake manifold 30 mm dan throttle body 28 mm menghasilkan daya tertinggi sebesar 10,97 HP pada 6500 RPM. Modifikasi ini menghasilkan peningkatan torsi sebesar 10,37% dan peningkatan daya sebesar 14,27% dibandingkan dengan kondisi motor standar. Air fuel ratio (AFR) yang dihasilkan dengan modifikasi intake manifold dan throttle body secara keseluruhan menunjukkan bahwa Kombinasi 3 dan Kombinasi 4 memberikan pengaturan AFR yang lebih baik pada RPM tinggi dibandingkan dengan kondisi standar. Konsumsi bahan bakar terbaik dicapai pada kombinasi 3, dengan konsumsi terendah sebesar 140 mL, sedangkan motor standar mencatat konsumsi tertinggi sebesar 250 mL. Kombinasi lainnya juga lebih efisien daripada kondisi standar, dengan konsumsi bervariasi antara 150 mL hingga 170 mL. Kata kunci: performa mesin, throttle body, porting polish, intake manifold, Yamaha Mio M3, injeksi, efisiensi bahan bakar.
