Abstract

In the present study, effects of fuel properties; such as viscosity and
density of different biodiesels on engine exhaust emissions were investigated.
Sunflower, corn and canola oils were used as raw materials of biodiesel fuels
which were produced via transesterification method. In experiments, pure
biodiesels were used as test fuels and diesel was used as reference fuel. The
results indicated that viscosity and density of biodiesel fuels went up with
higher proportion of biodiesel. Engine experiments, which were conducted on a
Mitsubishi Canter 4D34-2A, four-stroke, four cylinder diesel engine indicated
that carbon monoxide (CO) emission reduced with utilization of fuels that have
higher viscosity and density. On the  
other hand, carbon dioxide (CO₂) and nitrogen oxide (NOx)
emission had opposite trend. Both emission values were increased with higher
biodiesel ratios.
