Deskripsi Singkat
Minyak atsiri (eugenol dan sitronelal) yang diisolasi dari daun cengkeh (Syzygium aromaticum) dan sereh wangi (Cymbopogon nardus), dapat dijadikan bahan tambahan (additive) bahan bakar untuk meningkatkan efisiensi pembakaran. Hasil pengujian nilai kalor menunjukkan penggunaan eugenol dalam bahan bakar solar meningkatkan nilai kalor sebesar 10%, sementara sitronelal sebesar 17%. Penambahan eugenol mampu menurunkan konsumsi bahan bakar solar hingga 30%, sedangkan sitronelal sebesar 37%. Uji emisi juga menunjukkan penurunan konsentrasi gas CO, NO, SO maupun total partikulat.
Description :
Essential oils (eugenol and citronellal) isolated from clove (Syzygium aromaticum) and citronella (Cymbopogon nardus) leaves, can be used as additives for fuel to increase combustion efficiency. The results of the heating value test show the use of eugenol in diesel fuel increases the heating value by 10%, while citronellal by 17%. The addition of eugenol can reduce diesel fuel consumption by 30%, while citronellal by 37%. Emission tests also showed a decrease in CO, NO, SO gas concentrations as well as in total particulates.
