Abstract
In recent research, further studies on the measurement and analysis of particulate morphology have become necessary to decrease the negative effect of particulate (PM) characteristics. The influence of Coconut biodiesel (CB100) and rates of EGR technique on morphological characteristics of PM was studied using CI diesel engine. The results showed that the PM size distribution decreased by 36.27% from CB100 combustion in comparison with diesel for different EGR rates. Furthermore, introduce high rate of EGR contribute in increasing the PM formation by 26.48% from the CB100 combustion compared with absence EGR technique. It is indicated that the number of particulates significantly decreased by 42.35% when the engine fed with CB100 compared to the diesel. The presence EGR technique leads to decrease the radius of gyration (Rg) and diameter of soot particles by 31.75% and 27.38%, respectively, for both fuels; this trend is more clearly with CB100 combustion. The fractal dimension (Df) declined as the EGR rate increasing during the burning of CB100 by 44.93% in comparison with neat diesel. For both fuels, the presence 40% of EGR increased the fractal dimension by 1.76 and 1.97 from CB100 and diesel, respectively, compared to the absence EGR. 10.37934/arfmts.119.1.134145
