Numerical simulation of combustion and emission in medium-duty diesel engine fuelled with biodiesel blended fisher-tropsh diesel

This numerical simulation study investigates the combustion and emission of biodiesel blended Fisher-Tropsh (F-T) diesel fuels in a medium-duty diesel engine. It shows that diesel engine fuelled with F-T diesel and biodiesel blended fuels has better practicability. With the ESE module of FIRE software, the diesel of engine model is set up and the correctness is corroborated by the test result. Based on this, the paper carries on a simulation analysis of combustion and emission of biodiesel blended F-T diesel, and makes a contrast with diesel on the mean pressure, mean temperature, as well as the mass fraction of nitrogen monoxide (NO) and soot. The result shows that, the higher proportional, the lower mean pressure in-cylinder. NO grows later and its mass fraction is lower. Besides, the mass fractions soot of mixed fuels is far below diesel. © 2013 by CESER Publications.
