Abstract

Menurut data World Energy Outlook (WEO) tahun 2023, konsumsi bahan bakar transportasi menggunakan bahan bakar fosil (bensin dan solar) di seluruh dunia meningkat sekitar 1,5% per tahun. Oleh karena itu, diperlukan pengembangan Energi Baru Terbarukan (EBT) seperti bahan bakar etanol. Bahan bakar etanol memiliki nilai oktan tinggi dan nilai kalor
penguapan laten yang lebih tinggi dari bensin. Untuk menggunakan etanol, diperlukan penyesuaian pada konstruksi mesin, salah satunya dengan memodifikasi sistem pengapian (ignition coil). Modifikasi ini bertujuan untuk memperbesar percikan bunga api dari busi agar campuran bahan bakar dan udara terbakar lebih sempurna dan efisien. Metode penelitian yang digunakan adalah eksperimen yang dilakukan pada mobil urban Nogogeni VI dengan menggunakan bahan bakar etanol (E-100). Pengujian dilakukan dengan variasi koil standar, MSD, dan Uma Racing. Untuk menguji unjuk kerja mesin, digunakan alat dynometer, buret ukur, dan gas analyzer. Hasil pengujian meliputi daya, konsumsi bahan bakar, dan kadar emisi gas buang kendaraan. Hasil pengujian menunjukkan adanya perbedaan daya, torsi, konsumsi bahan bakar, dan emisi gas buang kendaraan yang dihasilkan. Unjuk kerja mesin terbaik dihasilkan oleh variasi koil MSD. Dengan nilai rata-rata daya (P) sebesar 4,66 HP, nilai ratarata torsi (T) sebesar 9,46 N.m, nilai rata-rata BSFC sebesar 0,00022 Kg/W-h, nilai rata-rata BMEP sebesar 951,29 kPa, dan nilai rata-rata efisiensi termal sebesar 37,5%. Emisi terendah dihasilkan oleh koil standart dengan nilai Carbon Monoksida (CO) sebesar 0,23% dan nilai Carbon Dioksida (CO2) sebesar 2,8%.

According to World Energy Outlook (WEO) data for 2023, transportation fuel consumption using fossil fuels (gasoline and diesel) worldwide is increasing by about 1.5% per year. Therefore, it is necessary to develop renewable energy such as ethanol fuel. Ethanol fuel has a high octane value and higher latent heating value of vaporization than gasoline. To use ethanol, adjustments are needed to the engine construction, one of which is by modifying the ignition coil system. This modification aims to increase the spark from the spark plug so that the fuel and air mixture burns more perfectly and efficiently. The research method used is an
experiment conducted on a Nogogeni VI urban car using ethanol fuel (E-100). Tests were conducted with variations of standard, MSD, and Uma Racing coils. To test engine
performance, a dynometer, measuring burette, and gas analyzer were used. The test results include power, fuel consumption, and exhaust emission levels. The test results showed differences in power, torque, fuel consumption, and exhaust emissions. The best engine performance is produced by the MSD coil variation. With an average value of power (P) is 4.66 HP, an average value of torque (T) is 9.46 N.m, an average value of BSFC is 0.00022 Kg/W-h, an average value of BMEP is 951.29 kPa, and an average value of thermal efficiency of 37.5%. The lowest emissions were produced by the standard coil with a Carbon Monoxide (CO) value is 0.23% and a Carbon Dioxide (CO2) value is 2.8%.
