Abstract

Meningkatnya kekhawatiran lingkungan atas pemanasan global dan menipisnya cadangan bahan bakar fosilmendorong para peneliti untuk meneliti bahan bakar ramah lingkungan seperti bahan bakar etanol, methanoldan butanol yang tidak hanya menunjukkan penurunan emisi secara optimal tetapi juga meningkatkan kinerjamesin. Penelitian ini menekankan pengaruh campuran bahan bakar etanol, methanol dan butanol yang berbedadalam bensin terhadap kinerja mesin dan emisi untuk kecepatan mesin berkisar antara 4000 hingga 9000 rpm.Hasil kinerja yang diperoleh menunjukkan bahwa daya output dan efisiensi termal meningkat denganpeningkatan persentase campuran etanol, methanol dan butanol dalam bensin. Konsumsi bahan bakar spesifikminimum (SFC) dipastikan menggunakan bensin murni diikuti oleh MBE1, MBE2 dan kemudian MBE3. EmisiHC mengalami peningkatan dari MBE1, MBE2, MBE3 dan bensin murni. MBE3 mempunyai kinerja lebih baikdi antara semua campuran dalam hal emisi gas buang dan kinerja mesin. Namun, MBE3 yang dicampur denganbensin secara signifikan mengurangi CO. MBE3 menghasilkan emisi CO 25% lebih rendah dibanding MBE2dan bensin murni.Kata Kunci : Metanol-Butanol-Etanol (MBE), Ramah Lingkungan,  Performansi.

Abstract

Alternative fuels such as Methanol-Butanol-Etanol (MBE) are worthy of development because of their optimal characteristics in SI engines. Selective government regulations on vehicle emissions require a shift to environmentally friendly innovative energy. Fuel-containing alcohol has been proven to reduce pollution levels in vehicles optimally. This research has explored MBE fuel mixtures with three variants through experimental methods. Variations MBE1, MBE2 and MBE3 were mixed with gasoline (RON-90) with capacities (5:2:1, 8:4:1, and 10:6:1)v/v when tested using a dyno test on an SI engine automatic type compression ratio 10:1 with a speed gap of 4000-9000rpm. During testing, torque and Mep experienced an optimal increase in MBE3 fuel of 10.78% and 10.55% compared to commercial fuel (RON-90). Engine power and thermal efficiency increased respectively by 10.03% and 10.69%. This condition is inversely proportional to SFC, which decreased by 21.05%. Furthermore, CO and HC exhaust emissions decreased by 12.12% and 4.60% respectively. This phenomenon shows that MBE fuel shows environmentally friendly performance and exhaust emissions for SI engines in daily activities.
