Application to Small-sized Diesel Engine of Biodiesel Fuel Generated from Rapeseed Oil

Abstract

Recently, biomass has been seen as a means to fight global warming. Specifically, rapeseed oil and other wasted cooking oil are converted into biodiesel (BDF) ; and they already act as substitutes for diesel fuel in America, Europe and Japan. In this research, the properties of BDF from domestically produced rapeseed oil were studied, along with its performance and emissions when used as engine fuel. The results showed similar engine performance when either BDF or diesel fuel were used ; with a slightly higher thermal efficiency at higher loads in case of BDF. In terms of emissions, the BDF generated more CO₂ and NOx than diesel fuel when compared based on the ISO 8178-4 standard ; contrarily CO emissions were reduced.
