摘要: | 提供用于控制在四汽缸发动机中的发动机运转模式之间的转变期间的振动的方法和系统。一种方法包括正时发动机运转在具有点火事件顺序的二汽缸、三汽缸与四汽缸模式之间的转变,使得相继的点火事件由至少120度曲轴转角间隔分开。由转变引起的振动可以通过调整活动安装座来抵消,该活动安装座与配气机构切换螺线管同步被调整。 | ||
摘要(英文): | Methods and systems are provided for controlling vibrations during transitions between engine operating modes in a four-cylinder engine. One method includes timing a transition in engine operation between two-cylinder, three-cylinder, and four-cylinder modes with a sequence of firing events such that successive firing events are separated by at least 120 crank angle degree intervals. Vibrations resulting from transitions may be countered by adjusting active mounts, the active mounts being adjusted in synchronization with a valvetrain switching solenoid. |
