Abstract

This study investigates
the injection and combustion parameters of a heavy duty diesel engine fueled
with biodiesels such as waste palm oil methyl ester (WPOME) and canola oil methyl
ester (COME). In this study, the engine tests were conducted at 1000, 1500 and
2000 rpm of constant engine speeds under the full load condition. The experimental
results show that when the heavy duty diesel engine was fueled with WPOME or
COME, the engine performance weakened in comparison with the fossil diesel fuel (FDF); on average, the brake power reduced by 4.2% while brake
specific fuel consumption (bsfc) increased
by 9.2%. But, the net indicated work areas obtained by use of biodiesels
were slightly wider than pure FDF. When using biodiesels in the test engine,
the start of injection timing take placed earlier than FDF.
