| Abstract: | Vegetable oil derived fuels for diesel engines are becoming important as alternative to petroleum diesel fuels due to their
environmental friendliness and availability. Ignition quality in compression ignition (CI) engines is influenced by thermal
characteristics and fuel properties. In this study, the effects of vegetable oil transesterification and vegetable oil–1-butanol-diesel
blends on fuel properties, cetane number (CN) and thermal characteristics were experimentally investigated. Methyl esters
(biodiesel) and 10% vegetable oil–10% 1-butanol–80% diesel blends were prepared from croton oil (CRO), coconut oil (COO) and
jatropha oil (JAO). CN was measured in a CFR F-5 engine, and a thermogravimetric analysis (TG), as well as the determination
of fuel properties of vegetable oils, biodiesels and blends was carried out. It can be observed for vegetable oils that they
possess low volatility characteristics, low CN and high viscosity different from those of biodiesels, blends and diesel fuel.
It was observed that biodiesels and blends exhibit similarities with diesel in the fuel characteristics, CN and TG curves. |
