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

在压燃式柴油发动机中加入 EGR 率和椰子生物柴油对颗粒物形态特征的影响

在最近的研究中，有必要进一步研究颗粒物形态的测量和分析，以减少颗粒物（PM）特性的负面影响。使用 CI 柴油发动机研究了椰子生物柴油（CB100）和 EGR 技术对可吸入颗粒物形态特征的影响。结果表明，与柴油相比，在不同的 EGR 率下，CB100 燃烧产生的 PM 粒径分布减少了 36.27%。此外，与不采用 EGR 技术相比，采用高 EGR 率会使 CB100 燃烧产生的可吸入颗粒物增加 26.48%。结果表明，与柴油相比，使用 CB100 的发动机的微粒数量明显减少了 42.35%。采用 EGR 技术后，两种燃料的烟尘颗粒的回旋半径（Rg）和直径分别降低了 31.75% 和 27.38%；CB100 燃烧时这一趋势更为明显。与纯柴油相比，CB100 燃烧时的分形维数（Df）随着 EGR 率的增加而下降了 44.93%。对于这两种燃料，与不使用 EGR 时相比，使用 40% 的 EGR 会使 CB100 和柴油的分形维数分别增加 1.76 和 1.97。10.37934/arfmts.119.1.134145
