摘要/Abstract

摘要： 基于分段韦伯函数燃烧放热率模型，通过耦合一维流体动力学软件GTPower与化学动力学软件Chemkin，建立了HCCI(Homogeneous Charge Compression Ignition)柴油发动机仿真试验平台，准确模拟了HCCI单缸试验样机的工作过程，研究了内外部EGR(Exhaust Gas Recirculation)对柴油HCCI燃烧控制的影响.仿真结果表明：内外部EGR对HCCI燃烧具有不同的控制作用，考虑内外部EGR的综合因素效应，可以实现燃烧相位的有效控制

Abstract: Based on the Partition Webie Function, with the GT-Power and Chemkin software, a simulation test platform was set up for HCCI engines. The working process of singlecylinder HCCI test engines was simulated. Effects of internal and external EGR on Diesel HCCI Combustion were accurately researched. Experimental results show that internal and external EGR have different effects on Diesel HCCI Combustion and that the HCCI combustion phase can be effectively controlled if the factors of internal and external EGR are combined.
