Abstract

Mesin otto merupakan salah satu sumber energi utama yang digunakan untul mengkonversi bahan bakar menjadi energi mekanik untuk menggerakan kendaraan, baik mobil maupun sepeda motor. Dalam upaya untuk meningkatkan performa mesin, instrumen berupa bangku uji sering digunakan untuk mengukur efisiensi mesin otto. Dalam penelitian ini, proses rancang bangun bangku uji dilakukan dengan tujuan untuk mengukur efisiensi volumetrik dan engine power loss dari mesin motor dengan bahan bakar bensin. Dari hasil pengujian untuk mesin dalam kondisi tanpa beban (idle), dikethaui bahwa efisiensi volumetrik terbesar adalah sebesar 66,7% pada saat kondisi katup terbuka penuh. Faktor lain yang mempengaruhi efisiensi volumetrik dari motor bakar adalah putaran mesin, di mana efisiensi volumetrik menurun pada saat putaran mesin makin cepat. Selain itu, perhitungan engine power loss menunjukan bahwa semakin tinggi putaran mesin, engine power loss semakin bertambah yang mungkin disebabkan oleh adanya peningkatan friction loss dan pumping loss.

Abstract

Due to increasing fuel prices, most people in Indonesia choose to use fuel with an octane rating of 90. However, using fuel with a lower Research Octane Rating or RON can affect the performance and efficiency of vehicle engines, especially if the compatibility between fuel octane and the engine's compression ratio is neglected. One solution to this problem is adding an octane booster to RON-90 gasoline to resemble gasoline with an octane rating of 92. The purpose of this research is to conduct an experimental study to see the effect of using a commercially available octane booster on the fuel consumption of a multi-purpose vehicle with an engine capacity of 1500 cc. Fuel consumption testing was performed using a road test based on the full-to-full method. The measurement results show that using an octane booster in RON -90 gasoline can reduce vehicle fuel consumption by 6.82%. However, the decrease in fuel consumption is still less compared to vehicles using RON-92 gasoline. Economic analysis found that using an octane booster in a motorcar could be a cost-efficient alternative to a more expensive RON-92 petrol.
