Abstract:

“Abstrak:Penelitian ini merupakan studi eksperimental pengaruh penambahan etanol terhadap kinerja mesin pembakaran busi (mesinbensin), meliputi daya efektif dan konsumsi bahan bakar spesifiknya. Mesin yang digunakan dalam penelitian ini berupa mesinempat langkah silinder tunggal, system injeksi tidak langsung, dengan volume 124.8 cc dan rasio kompresi 9.3 : 1. Pengujiandilakukan pada 8 kecepatan putaran mesin yang berbeda mulai dari 1500 rpm sampai 5000 rpm, dengan 10 tipe campuranbensin dan etanol (E10 sampai E100). Hasil pengujian menunjukkan bahwa daya efektif mesin menurun dengan peningkaranetanol dalam campuran untuk semua variasi kecepatan putaran mesin. Daya maksimum dicapai pada putaran mesin 2500sampai 3000 rpm. Etanol memiliki nilai kalor yang lebih rendah dibanding bensin, sehingga peningkatan kandungan etanoldalam bahan bakar menyebabkan kenaikan konsumsi bahan bakar spesifik mesin.Kata kunci: etanol; bahan bakar bensin-etanol; performa mesin, konsumsi bahan bakar spesifikAbstract:This present study investigated experimentally the influence of ethanol addition on the engine performance; in the term ofeffective power and Brake specific fuel consumptio of gasoline spark ignition engine. The engine used in the research was a 4stroke single-cylinder, indirect injection system with volume of 124.8 cc and compression ratio of 9.3:1. The experiments wereconducted at eight different engine speeds ranging from 1500 rpm to 5000 rpm and 10 types of gasoline-ethanol mixtures (E10to E100). The result showed that the effective power decreased with increasing of ethanol in the fuel blends for all variation ofengine speed. The maximum power of the engine was obtained at engine speed around 2500 to 3000 rpm. Since the ethanolhas a lower heating value than that of gasoline, ethanol addition in the blend fuel causes the increment of Brake Specific FuelConsumptionKeywords: ethanol; gasoline-ethanol fuel; spark ignition engine; engine performance, brake spesific fuel consumption”
