The utility model provides an engine subtracts heavy cam, the cam base circle of cam is equipped with in the bilateral symmetry and subtracts heavy recess, what the both ends border that subtracts heavy recess was located the cam buffer segment respectively begins department and end. The utility model discloses a subtracting the weight of thickness in order to subtract small cam of small cam base circle part, utilizing cam weight little, inertia is little, can respond rapidly, and then make the engine air input increase, and waste gas is discharged more thoroughly. And the cam remains unchanged with active section and the buffer segment thickness that tappet or rocking arm contacted, satisfies the strength requirement of above -mentioned part. 本实用新型提供的发动机减重凸轮，所述凸轮的凸轮基圆在两侧对称设有减重凹槽，所述减重凹槽的两端边界分别位于凸轮缓冲段的开始处和结束处。本实用新型通过减小凸轮基圆部分的厚度以减小凸轮的重量，利用凸轮重量小，惯性小，能够迅速响应，进而使发动机进气量增加，废气排出更彻底。而凸轮与挺柱或摇臂接触的工作段和缓冲段厚度保持不变，满足上述部分的强度要求。
