Abstract

The main objective of this
study is to evaluate the effect on diesel engine performance, exhaust emission
and combustion characteristics of canola oil biodiesel. The biodiesel was
blended with petroleum-based diesel fuel (DF) by 10% (B10), 20% (B20) and 50%
(B50) volumetrically. Engine tests were carried out on a direct injection,
single-cylinder, compression ignition engine at different engine loads and the
results were compared with the reference DF. The results showed that the
maximum cylinder pressure and heat release rate values of DF were higher than
those of the biodiesel blends at all engine loads. The addition of biodiesel to
DF increased the brake specific fuel consumption (BSFC) and decreased the brake
thermal efficiency (BTE) at all engine loads. In addition, biodiesel blends
caused a slight increase in nitrogen oxide (NO_x) emissions while
causing a decrease in smoke opacity and carbon monoxide (CO) emissions.
