1. a multi-link engine, comprising:

  • Engine cylinder-body, described engine cylinder-body comprises at least one cylinder;

    Piston, described piston is disposed in the cylinder of described engine cylinder-body in the mode that can move back and forth;

    Upper connecting rod, the first end of described upper connecting rod is pivotally attached to described piston by wrist pin;

    Lower link, described lower link is rotatably installed on the crank pin of bent axle and is connected to the second end of described upper connecting rod by upper pin;

    AndControl link, described control link has first end and the second end, and the first end of described control link is pivotally connected to described lower link by controlling pin, and the second end of described control link can be installed on the hinge portion of Control Shaft pivotally,Described upper connecting rod, described lower link and described control link are relative to each other constructed and are configured to, make to specify the inertial force of exponent number laterally to act on described upper connecting rod, described lower link and described control link in left-right direction relative to piston movement direction according at least one in the above inertial force of the second order of engine speed, make the summation of the inertial force horizontal in left-right direction acting on the center of gravity of described control link and the center of gravity of described lower link, be substantially equal to the inertial force horizontal in left-right direction of the center of gravity acting on described upper connecting rod.
