摘　　要：概述了国内外可变压缩比技术(VCR)在发动机领域节能的应用,重点分析了几大发动机厂家VCR技术路线的结构、节油潜力与效果。最后指出,可变压缩比技术(VCR)与均质压燃(HCCI)、增压小型化、废气再循环(EGR)等技术的结合应用是今后发动机的一个发展趋势,但仍需在可靠性、振动噪声以及成本等方面做出努力。Recent progress of variable compression ratio(VCR)technology in the development of energy saving application engine is discussed in this paper.The structure,fuel saving potential and effect of VCR technology route of several major engine manufacturers are emphatically analyzed.Finally,it is pointed out that the application of VCR technology combined with homogeneous charge compression ignition(HCCI),miniaturization of supercharging and exhaust gas recirculation(EGR)technology is a trend of engine development in the future.But we still need to make efforts in terms of reliability,vibration,noise and cost.
