Abstract:
The reflected shock using CHEMKIN model to simulate biodiesel combustion, analyze the effects ofdifferent equivalence ratio and EGR rate on the biodiesel soot precursor polyeyelic aromatic hydrocarbons onbenzene , 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 , inhibitedthe formation of polyeyclic aromatic hydrocarbons, decreased the soot ,ECR rate of 0 ,0 ,5% , 10% , 20% and40% benzene curves almost coincide in the prophase, 40% EGR rate higher after 4 us, naphthalene, phe.nanthrene , pyrene increased with the increase of EGR rate.
