Zusammenfassung:	The invention relates to a variable displacement engine including different cam lobe profiles. Methods and systems are provided for an engine including cams having different lobe profiles. In one example, cams of a first cam group drive a plurality of deactivatable cylinder valves and cams of a second cam group drive a plurality of non-deactivatable cylinder valves. The cams of the first cam groupinclude a different lobe profile relative to cams of the second cam group. 本申请涉及包括不同凸轮凸角轮廓的可变排量发动机，并且提供用于包括具有不同凸角轮廓的凸轮的发动机的方法和系统。在个示例中，第凸轮组的凸轮驱动多个可停用汽缸气门，并且第二凸轮组的凸轮驱动多个不可停用汽缸气门。第凸轮组的凸轮包括相对于第二凸轮组的凸轮不同的凸角轮廓。
