Abstract

The purpose of this study was to determine the differences in torque, power, and specific fuel consumption produced by four-stroke motorcycles with different compression ratios and using different fuels. This study used an experimental method. The results of the study at a standard compression ratio of 9.6:1, the highest torque was 12.17 Nm using Pertamax Plus fuel, while the highest power was 5.77 Kw using Pertamax Plus fuel, and the lowest specific fuel consumption was in the use of Pertamax Plus fuel at 0.1192 Kg/kWh. At a compression ratio reduced to 8.9:1, the highest torque was 9.38 Nm using Pertamax Plus fuel, while the highest power was 4.03 Kw using Pertalite and Pertamax Plus fuel, while the lowest specific fuel consumption was in the use of Pertamax Plus fuel at 0.1537 Kg/kWh. When the compression ratio is increased to 10.3:1, the highest torque is 20.19 Nm using Pertamax Plus fuel, while the highest power is 6.67 Kw using Pertamax Plus fuel, while the lowest specific fuel consumption is when using Pertamax Plus fuel at 0.1258 Kg/kWh. ABSTRAK Tujuan penelitian adalah untuk mengetahui perbedaan torsi, daya dan konsumsi bahan bakar spesifik yang dihasilkan dari sepeda motor empat langkah dengan perbandingan kompresi berbeda dan menggunakan bahan bakar yang berbeda. penelitian ini menggunakan metode eksperimental. Hasil penelitian pada perbandingan kompresi standar 9,6:1 torsi tertinggi sebesar 12,17 Nm menggunakan bahan bakar pertamax plus, sedangkan daya tertinggi sebesar 5,77 Kw menggunakan bahan bakar pertamax plus, dan konsumsi bahan bakar spesifik terendah pada penggunaan bahan bakar pertamax plus 0,1192 Kg/kWh. Pada paat perbandingan kompresi diturunkan 8,9:1 torsi tertinggi sebesar 9,38 Nm menggunakan bahan bakar pertamax plus, sedangkan daya tertinggi sebesar 4,03 Kw menggunakan bahan bakar pertalite dan pertamax plus, sedangkan konsumsi bahan bakar spesifik terendah pada penggunaan bahan bakar pertamax plus 0,1537 Kg/kWh. Pada saat perbandingan kompresi dinaikkan 10,3:1 torsi tertinggi sebesar 20,19 Nm menggunakan bahan bakar pertamax plus, sedangkan daya tertinggi sebesar 6,67 Kw menggunakan bahan pertamax plus, sedangkan konsumsi bahan bakar spesifik terendah pada penggunaan bahan bakar pertamax plus 0,1258 Kg/kWh.
