Abstract
A variable length connecting rod includes a connecting rod body, an eccentric member, a switching mechanism and a stopping mechanism. The eccentric member is provided at a small diameter end of the connecting rod body. The eccentric member rotates such that an effective length of the variable length connecting rod is varied. The switching mechanism includes a hydraulic piston connected to the eccentric member. The eccentric member reaches a first position when the switching mechanism is in a first state. The eccentric member reaches a second position when the switching mechanism is in a second state. The stopping mechanism includes a stopping member that abuts against or engages with the eccentric member or the hydraulic piston such that the eccentric member is maintained at an intermediate position between the first position and the second position.
