Abstract
The objective of the present experimental work is the production of biodiesel and
to examine the effects of different blends of biodiesel with diesel on the exhaust
emission and performance characteristics of an existing agricultural diesel engine
and to select a suitable blend of biodiesel with diesel. The suitability of a blend
of biodiesel with diesel is related with the reduction in exhaust emissions and
brake specific fuel consumption (BSFC), together with an increase in brake
thermal efficiency (BTE). Experimental work started with the production of
biodiesel obtained from Jatropha curcas in our own mini biodiesel plant.
Biodiesel is blended with diesel at different ratios to obtain different blends, such
as B10 (10% biodiesel + 90% diesel by volume), B20, B30, B40, B50, B60, B70,
B80, B90 and B100. Experimental results show that BSFC at all loads is less for
blends B10 to B50 compared to that of diesel. BTE at all loads is higher for
blends up to B60 compared to diesel and after B60 it is more or less the same as
diesel. Engine emissions of CO, HC, and also NOx to some extent, are less for
all blends from B10 to B100. Among the blends, B10 has lowest BSFC, lowest
emission and highest BTE. Higher biodiesel blends can also be used with
suitable modifications to arrest some NOx. The present investigation is thus
directed to the on-going research towards the search for viable alternative fuels
for energy security, environmental problem mitigation and sustainable
development.
