Abstract

Untuk meningkatkan kinerja mesin pada motor 4 tak injeksi 110cc, penerapan sistem dual fuel/ merupakan strategi inovatif yang menarik. Penelitian ini secara khusus fokus pada sistem dual fuel/ LPG-Pertalite, dengan mempertimbangkan peningkatan torsi, daya, efisiensi bahan bakar dan penurunan emisi gas buang. Penelitian ini bertujuan untuk menguji sistem dual fuel/ LPG-Pertalite pada sepeda motor injeksi dengan memvariasikan waktu pengapian dan durasi injeksi berdasarkan remapping/ ECU standar, serta menganalisis dampaknya terhadap kinerja mesin. Metode penelitian ini adalah eksperimen yang menguji kinerja mesin motor 4 tak 110 cc injeksi dengan membandingkan variasi waktu pengapian dan durasi injeksi yang telah dimodifikasi menjadi dual fuel/ LPG-Pertalite. Variasi yang dilakukan mencakup waktu pengapian 12.5˚, 15˚, dan 17.5˚ (BTDC), serta durasi injeksi -5%, 0%, dan +5%. Kinerja mesin, termasuk torsi, daya, dan SFC, diukur menggunakan dynometer dan tambahan buret, sedangkan emisi gas buang diukur dengan exhaust gas analyzer/. Hasil penelitian menunjukkan bahwa variasi waktu pengapian dan durasi injeksi, baik secara terpisah maupun bersamaan, memiliki pengaruh signifikan terhadap kinerja mesin dan emisi gas buang. Kombinasi optimal ditemukan pada waktu pengapian 17.5˚ BTDC dan durasi injeksi -5%, yang mampu meningkatkan daya dan torsi mesin sambil mempertahankan efisiensi bahan bakar dan mengurangi emisi. Temuan ini menunjukkan potensi besar sistem dual fuel/ LPG-Pertalite sebagai alternatif bahan bakar yang efisien dan lebih ramah lingkungan untuk sepeda motor injeksi, meskipun kalibrasi ECU yang tepat diperlukan untuk memaksimalkan manfaatnya. ***** To improve engine performance in a 110cc 4-stroke injection motor, the application of a dual fuel system is an attractive innovative strategy. This study specifically focuses on the LPG-Pertalite dual fuel system, considering improvements in torque, power, fuel efficiency, and reduced exhaust emissions. The aim of this research is to test the LPG-Pertalite dual fuel system on an injection motorcycle by varying the ignition timing and injection duration based on standard ECU remapping, and analyzing its impact on engine performance. The research method is an experiment that tests the performance of a 110 cc 4-stroke injection motorcycle engine by comparing variations in ignition timing and injection duration that have been modified to dual fuel LPG-Pertalite. The variations included ignition timing of 12.5˚, 15˚, and 17.5˚ (BTDC), as well as injection duration of -5%, 0%, and +5%. Engine performance, including torque, power, and SFC, was measured using a dynamometer and additional buret, while exhaust emissions were measured with an exhaust gas analyzer. The research results indicate that variations in ignition timing and injection duration, both individually and in combination, have a significant impact on engine performance and exhaust emissions. The optimal combination was found at an ignition timing of 17.5˚ BTDC and an injection duration of -5%, which enhances engine power and torque while maintaining fuel efficiency and reducing emissions. These findings highlight the great potential of the LPGPertalite dual fuel system as an efficient and more environmentally friendly fuel alternative for injection motorcycles, although proper ECU calibration is required to maximize its benefits.
