Abstract

Bahan bakar biodiesel merupakan energi alternatif yang dapat digunakan sebagai pengganti bahan bakar diesel, namun memiliki kandungan NOx yang tinggi. Untuk mengurangi tingkat NOx yang tinggi yang dihasilkan oleh biodiesel, penambahan n-butanol diharapkan dapat mengurangi emisi NOx dari biodiesel. Dalam penelitian ini, dilakukan perbandingan kinerja dan emisi NOx menggunakan campuran bahan bakar B50 dan n-butanol. Metode penelitian yang digunakan adalah berbasis eksperimen dengan campuran murni B50 dan B50Bu10, serta B50Bu20. Dari hasil pengujian kinerja yang dilakukan, ditemukan bahwa penggunaan campuran bahan bakar B50Bu10 dan B50Bu20 mengalami peningkatan kinerja yang signifikan. Penambahan 10% dan 20% n-butanol mengalami peningkatan daya sebesar 7,69% dan 9,03%, serta peningkatan torsi sebesar 7,5% dan 9,2% dibandingkan dengan B50 murni. Namun, penambahan 10% dan 20% n-butanol menyebabkan peningkatan SFOC sebesar 3,23% dan 13% dibandingkan dengan B50 murni. Hasil pengujian emisi NOx juga dilakukan, dan ditemukan bahwa penambahan 10% dan 20% n-butanol menyebabkan penurunan emisi NOx mesin sebesar 7,3% dan 17,56% dibandingkan dengan B50 murni.

Biodiesel fuel which can be used as a substitute for diesel fuel, produces a high amount of NOx. To mitigate the elevated NOx levels associated with biodiesel, the introduction of n-butanol has been proposed as a means to reduce NOx emissions. This study involved comparing the performance and NOx emissions of B50 (50% biodiesel blend) with different butanol blends as fuels. The research methodology employed was experimental, comparing B50Bu10, B50Bu20, and pure B50. The performance tests revealed a significant improvement in performance when using B50Bu10 and B50Bu20 fuels. The addition of 10% and 20% n-butanol resulted in a power increase of 7.69% and 9.03% respectively, as well as a torque increase of 7.5% and 9.2% compared to pure B50. However, the addition of 10% and 20% n-butanol also caused an increase in specific fuel oil consumption (SFOC) of 3.23% and 13% respectively, compared to pure B50. Furthermore, the NOx emission tests demonstrated that the inclusion of 10% and 20% n-butanol contributed to a reduction in engine exhaust emissions of NOx by 7.3% and 17.56% respectively, in comparison to pure B50.
