Analisis Performa dan Emisi gas buang Mesin Diesel dengan Bahan Bakar Campuran Biodiesel-Alkohol


Farhan Maulana Rahman, Tatun Hayatun Nufus, Paulus Sukusno

Abstract


Dalam beberapa tahun, biodiesel sudah berkembang seiring dengan perkembangan industri. Salah satu perkembanganya adalah campuran biodiesel dengan zat atau fluida tambahan untuk meningkatkan performa dari mesin diesel dan mengurangi emisi gas buang. Salah satu campuran itu adalah biodiesel dan alkohol. Alkohol memiliki cold flow properties yang lebih rendah di bandingkan biodiesel. Maka penelitian ini bertujuan untuk menganalisis performa dan emisi gas buang mesin diesel yang menggunakan bahan bakar biodiesel-alkohol. Pada penelitian ini putaran mesin tidak berubah atau konstan, dan variable yang diuji untuk performa yaitu; daya mesin dan konsumsi bahan bakar terhadap beban yang berbeda.. Dari percobaan yang sudah dilakukan didapatkan bahwa bahan bakar campuran D70B20E10 memiliki konsumsi bahan bakar paling tinggi sebesar 2.83 l/h dengan daya sebesar 0.168 kW.. Untuk emisi gas buang CO bahan bakar campuran D70B20E10 terbesar 383 ppm. Untuk emisi gas NOx terbesar yaitu bahan bakar campuran D60B30E10 pada beban 3 kW sebesar 21 ppm
