Emission Characterization of Diesel Engine Run on Coconut Oil Biodiesel its Blends and Diesel
NICHOLAS, A. MUSA; GEORGINA, M. TERAN & SARAKI, A. YAMAN
Abstract
The use of biodiesel in running diesel has been called for, with a view to
mitigating the environmental pollution, depletion, cost and scarcity associated with the use
diesel in running diesel engine. So the need to characterize the emissions from these
biodiesel, cannot be overemphasized, hence this paper presents the evaluation of the
emissions of particulate matter (PM), carbon monoxide(CO), hydrocarbon(HC) and oxides
of nitrogen(NOX) from diesel engine run on coconut oil biodiesel, its blends and diesel for
comparison. The result of the evaluation showed that NOX emission increased with
increase in percentage of the biodiesel in the blend, while PM, CO, HC decreased with
increase in the percentage biodiesel in the blend. In comparison with diesel, diesel has the
least emission of NOX and the highest emission of PM, CO and HC.
