Abstract

Seiring perkembangan jaman, riset berkelanjutan dilakukan untuk mendapat bahan bakar yang lebih optimal dan lebih ramah lingkungan, para peneliti membuat sebuah terobosan baru yaitu bahan bakar green diesel. Green diesel adalah bahan bakar yang berasal dari minyak nabati, dan melalui proses hydrotreating untuk memisahkan kandungan oksigen di dalam minyak. Karakteristik dari bahan bakar green diesel lebih bagis dibandingkan bahan bakar solar pada umumnya. Dari segi performa, bahan bakar green diesel juga lebih baik dibandingkan bahan bakar solar. Penelitian ini berfokus pada proses pembakaran dan kadar emisi yang dihasilkan oleh bahan bakar green diesel. Pengujian data dilakukan pada 2200 RPM dan dengan beban mesin sebesar 25%, 50%, 75%, dan 100%. Dari hasil simulasi, diketahui bahwa bahan bakar green diesel menghasilkan tekanan dan temperature pembakaran lebih tinggi dibandingkan dengan biodiesel B30. Hal tersebut berpengaruh kepada kadar emisi NOx yang dihasilkan, karena NOx terbentuk dari temperatur dan tekanan pembakaran yang tinggi. Kadar NOx yang dihasilkan oleh bahan bakar green diesel lebih tinggi dibandingkan dengan biodiesel B30. ========================================================= As time goes by, ongoing research is carried out to obtain more optimal and more environmentally friendly fuels, the researchers make a new breakthrough namely green diesel fuel. Green diesel is a fuel derived from vegetable oil, and through a hydrotreating process to separate the oxygen content in the oil. The characteristics of green diesel fuel are better than diesel fuel in general. In terms of performance, green diesel fuel is also better than diesel fuel. This research focuses on the combustion process and emission levels produced by green diesel fuel. Data testing was carried out at 2200 RPM and with an engine load of 25%, 50%, 75%, and 100%. From the simulation results, it is known that green diesel fuel produces a higher combustion pressure and temperature compared to B30 biodiesel. This affects the resulting NOx emission levels, because NOx is formed from high temperatures and combustion pressures. NOx levels produced by green diesel fuel are higher than B30 biodiesel.
