    • Engine with a crank mechanism and a cylinder head whose intake and exhaust channels are regulated by gas exchange valves activated by cams of at least one camshaft. The cams are sliding cams with at least one cam per sliding cam assembly arranged rotationally fixed but axially displaceable on a base shaft, and each having an actuator with an actuator pin for displacing the sliding cam assemblies into different axial positions via at least one displacement groove which cooperates with the pin. The displacement groove being helical shaped and having a run-in and a run-out region for the pin and a displacement flank and an opposing support flank. A detent device locks the sliding cam assemblies in different axial positions. A distance between the displacement flank and the support flank remains constant along the entire extent of the displacement groove parallel to the displacement direction of the sliding cam assembly.
    • 具有曲柄机构和气缸盖的发动机,其进气通道和排气通道由至少一个凸轮轴的凸轮激活的气体交换阀调节。 凸轮是滑动凸轮,每个滑动凸轮组件具有至少一个凸轮,其旋转地固定但可在基轴上轴向移动,并且每个凸轮具有致动器,该致动器具有用于通过至少一个位移凹槽将滑动凸轮组件移动到不同的轴向位置 它与引脚配合。 位移槽是螺旋形的并且具有用于销的移入和偏移区域以及位移侧面和相对的支撑侧面。 定位装置将滑动凸轮组件锁定在不同的轴向位置。 位移侧面和支撑侧面之间的距离沿平行于​​滑动凸轮组件的位移方向的位移槽的整个范围保持恒定。
