当量比/EGR率对生物柴油多环芳香烃影响的理论分析
Theoretical Analysis of Infuence for Equivalence Ratio/EGR on the Biodiesel PAHs
摘要
Abstract
The reflected shock using CHEMKIN model to simulate biodiesel combustion, analyze the effects of different equivalence ratio and EGR rate on the biodiesel soot precursor polycyclic aromatic hydrocarbons on benzene, naphthalene, phenanthrene and pyrene. The results showed that: benzene, naphthalene, phenan-threne, pyrene mole fraction decreased with the increase of equivalence ratio form 1.0,1. 7to 2. 1 , inhibited the formation of polycyclic aromatic hydrocarbons, decreased the soot ,EGR rate of 0,0,5% , 10% , 20% and 40% benzene curves almost coincide in the prophase, 40% EGR rate higher after 4 祍, naphthalene, phenanthrene , pyrene increased with the increase of EGR rate.关键词
