 Abstract
In recently, lots of researcher have been attached to develope various alternative fuels and to use renewable fuels for solution of the exhaust emission problems. In this study, the usability of used vegetable oil as alternative fuel for diesel engines has been investigated. This paper was compared with the exhaust emissions and performance in diesel engine with used vegetable oil and conventional diesel fuel. Since the vegetable oil includes oxygen of about 10%, it influenced the combustion process strongly. So, the smoke emissions of used vegetable oil were exhausted to be lower than those of diesel fuel. Also, the used vegetable oil was much the same cycle to cycle variation with diesel fuel except d.theta.)max/, but the cycle to cycle variation of used vegetable oil was reduced significantly by preheating of the fuel and swirling of the intake air. It was concluded that used vegetable oil could be utilized effectively as renewable fuel for diesel engine.e.
