Studi Eksperimental EGT Dan Smoke Opacity Pada Mesin Diesel Menggunakan Bahan Bakar Campuran Jatropha Dengan Sistem Cold EGR

Eka Darmana

Abstract


Penipisan bahan bakar solar yang berasal dari fosil, mendorong manusia untuk mencari bahan bakar alternatif yang dapat diperbaharui. Salah satu bahan bakar alternatif yang dapat menggantikan bahan bakar fosil dan dapat diperbaharui adalah jatropha biodiesel. Penggunaan bahan bakar jatropha tidak menjatuhkan performa dari mesin diesel akan tetapi nilai emisi NOx jatropha lebih tinggi dibandingkan dengan bahan bakar solar. Tehnik EGR membantu mereduksi emisi NOx tersebut, akan tetapi masih diperlukan pengkajian dampak EGR terhadap smoke opacity mesin diesel dengan memakai bahan bakar jatropha biodiesel. Pengujian dilakukan pada putaran mesin konstan 2000 rpm, dengan memvariasi bukaan katup EGR dari 0% - 100% dengan inteval 25% pada setiap pembebanan. Pengujian dilakukan dengan bahan bakar D100 dan D30J70. Hasil penelitian menunjukkan bahwa EGT menurun ketika menggunakan cold EGR maupun bahan bakar jatropha. Smoke opacity meningkat ketika dioperasikan dengan sistem EGR. Peningkatan smoke opacity juga terjadi ketika menggunakan bahan bakar jatropha dibandingkan dengan bahan bakar solar (D100).

Kata kunci: diesel, EGT, smoke opacity, cold EGR, jatropha
