摘要：
A short duration cam of a variable valve lift apparatus has a cam lift acceleration including a first peak formed before a center of the cam lift acceleration, and a second peak formed after the center of the cam lift acceleration. A relative ratio of a smaller value to a greater value of the first peak and the second peak is 0.8 or more.
