1车用发动机的新型可变气门定时机构显示文摘可变气门定时机构(VAST)是专门为火花点燃式和压燃式发动机研制的。它使顶置凸轮轴和侧置凸轮轴的进、排气门可变控制成为可能。该机构在工作的过程中,凸轮在转动中角速度是不均匀的,因此改变凸轮的相对运动可以使气门的开启角和延续角发生变化(开启角大约可以变化50℃A,延续角大约可以改变30℃A)。在气门开启时,该机构开启气门的时间可以比作者所列举的任何一种可变气门定时机构(VVT)开启气门的时间都长。安装该机构的发动机,由于气门的提升过程直接受凸轮的作用,因此该机构可以用于各种气门传动方式,既可以用于单凸轮轴的发动机/缸盖传动方式,又可以用于多气门、双凸轮轴传动方式。该机构既可以用于火花点燃式发动机,又可以用于压燃式发动机。试验结果证明VVT系统组件可以满足高性能发动机的工作要求。与以前所使用的气门传动机构相比,摩擦力的水平基本相同。有关VAST机构对美国轿车发动机匹配的研究正在计划中。Hannibal W Bertsch A 宫焕久 2001国外内燃机2001,33,1:3
