连续可变气门持续时间装置及发动机
摘要：
一种连续可变气门持续时间装置及发动机，该连续可变气门持续时间装置可以包括：凸轮轴；第一凸轮部分和第二凸轮部分，凸轮分别形成在该第一凸轮部分和第二凸轮部分上，凸轮轴插入该第一凸轮部分和第二凸轮部分中使得相对于凸轮轴的相对相位角可变；第一内支架和第二内支架，将凸轮轴的旋转分别传输至第一凸轮部分和第二凸轮部分；滑动壳，第一内支架和第二内支架可旋转地插入该滑动壳；第一引导部分和第二引导部分，形成在滑动壳上；凸轮罩，接触第二引导部分的凸轮罩引导件形成在该凸轮罩上；控制轴，平行于凸轮轴；控制杆，偏心地形成在控制轴上；引导盖，盖引导部分和盖孔形成在该引导盖上；以及控制部分，使控制轴选择性地旋转。
摘要（英）：

A continuous variable valve duration apparatus may include: a camshaft; first and second cam portions on which a cam is formed respectively, the camshaft being inserted into the first and second cam portions such that relative phase angles with respect to the camshaft are variable; first and second inner brackets transmitting rotation of the camshaft to the first and second cam portions respectively; a slider housing in which the first and the second inner brackets are rotatably inserted; first and second guiding portions formed on the slider housing; a cam cap on which a cam cap guide contacting the second guiding portion is formed; a control shaft parallel to the camshaft; a control rod eccentrically formed on the control shaft; a guide head on which a head guiding portion and a head hole are formed; and a control portion selectively rotating the control shaft.
