摘　　要：应用约束变尺度优化法对汽油机的工作过程进行了优化计算研究，阐述了VVT、VCR法。研究结果表明，VVT法与VCR法相结合并配以最佳点火提前角，可充分改善汽油机的燃油经济性，能最大限度地挖掘出VVT法和VCR法的潜力。Optimum calculation and research have been carried out for gasolene engine work-ing process by means of restrained variable dimension method,and WT(variable valve timing)andVCR(Variable compression ratio)methods ars explained. Result of the research shows that fuel e-conomy of gasolene engine may be sufficiently improved by combining VVT method and VCRmethod with optimum ignition advance angle,and potentiality of WT method and VCR methodmay be exploited out to the greatest extent.
