Diesel engine performance and emission characteristics of biodiesel produced by the peroxidation process

摘要: Biodiesel is an alternative fuel that cleaner than petrodiesel. can be used directly as for a diesel engine without having to modify the system. It has major advantages of high biodegradability, excellent lubricity and no sulfur content. In this study, biodiesel produced by transesterification technique was further reacted using peroxidation process. Four types fuel, with additional process, commercial ASTM No. 2D were compared their properties, performance emission characteristics. The experimental results show consumption rate, brake thermal efficiency, equivalence ratio, exhaust gas temperature increased while bsfc, indices CO2, CO NOx decreased increase speed. three biodiesels showed higher at same time exhibited lower CO2 well when diesel. Moreover, process found have oxygen content, weight proportion saturated carbon bonds, bsfc process; lower. particular, addition had lowest ratio among all four test fuels. Therefore, effectively improve properties reduce emissions used.
