摘　　要：本文简要介绍了可变气门正时(VVT)及可变升程技术,提出了一种简单而实用的新型凸轮结构。这种凸轮结构,可以同时实现连续可变气门正时及连续可变气门升程,适应了无级式机电一体化可变气门正时及可变升程机构的发展趋势。This paper gives a brief introduction on the technology of variable valve timing （VVT） and variable -lift, and brings forward a new cam structure which is simple and practical. This cam structure can actualize continuous VVT and continuous variable - lift synchronously. It adapts to the development tendency of stepless electromechanically integrated VVT and variable -lift structure.
