1. A system for synchronization, comprising:
a first rocker arm configured to be switchable between a first mode and a second mode, wherein the first mode activates the first rocker arm to enable motion transfer to a first engine valve, and the second mode deactivates the first rocker arm to disable motion transfer to the first engine valve;
a second rocker arm configured to be switchable between a third mode and a fourth mode, wherein the third mode activates the second rocker arm to enable motion transfer to a second engine valve, and the fourth mode deactivates the second rocker arm to disable motion transfer to the second engine valve;
a first switching mechanism arranged in the first rocker arm and configured to controllably switch the first rocker arm between the first mode and the second mode by moving between a first position and a second position; and
a second switching mechanism arranged in the second rocker arm and configured to controllably switch the second rocker arm between the third mode and the fourth mode by moving between a third position and a fourth position;
wherein movement of the first switching mechanism and movement of the second switching mechanism are actuated by a single actuation source; and
wherein movement of the first switching mechanism between the first position and the second position causes the second switching mechanism to move between the third position and the fourth position such that switching of the first rocker arm and the second rocker arm occurs in sequence.
