Abstract
This paper presents the results of an investigation into the effect of fuel
composition on the emission characteristics of a four stroke, single cylinder,
Viking super direct injection diesel engine run at different operating conditions
using diesel fuel and soybean biodiesel blends (B15, B20 and B25). A
PerkinElmer 2400 series CHNS/O elemental analyser was used in determining
the fuel composition. Exhaust emission testing was conducted using Crowcon
gas sensors to quantify the concentration of Nitrogen dioxide (NO2), carbon
monoxide (CO) and sulphur dioxide (SO2) from the exhaust gases. The
relationships between the exhaust emissions, engine speed, torque, throttle
position and elemental fuel composition have been reported. The predictive
model equations were developed using multiple regression analysis to predict
exhaust emissions. The results show that the engine that is run on B15 gives the
lowest levels of Nitrogen dioxide (NO2) emissions of 2.58 ppm, carbon
monoxide (CO) emissions of 0.153 ppm and sulphur dioxide (SO2) emissions of
6.5 ppm when compared to other fuel blends. This outcome signals the
possibility of using B15 as an alternative fuel to diesel for a healthier
environment.
Keywords: fuel composition, soya biodiesel, emissions, environmental pollution.
