Performance and emissions of a CRDI diesel engine fuelled with swine lard methyl esters-diesel mixture

摘要

Biodiesel, as a product of the transesterification reaction of fatty material, is gaining appreciation all over the world and confirms its beneficial effect on the reduction of exhaust gases when (even partly) used to power compression-ignition engines. Although many researchers have focused on biofuel production and its application in combustion engines, continuous development of injection systems, providing new control strategies, encourages the seeking for new ways of optimizing biofuel combustion. In particular, very little attention has been given to the possibility of using biofuels in modern CRDI (Common Rail Direct Injection) engines with divided injection technology. There is also limited information available on engines operating on biodiesel of animal origin and their performance and emissions for such fuels.
