Abstract
The present disclosure relates to the technical field of power plants, and in particular to a dual-connection crank-piston mechanism, which includes a cylinder body, a piston, a crankshaft, and a frame. The piston and the crankshaft are hingedly connected to two connecting rods. Hinged ends of an inner connecting rod and an outer connecting rod are both hingedly connected to a slider or a swing arm. The slider is slidably connected to a guide rail. The swing arm is hingedly connected to the frame. Another end of the outer connecting rod is hingedly connected to a crankshaft shank. A stroke of the piston is greater than twice the length of the crankshaft handle. A upward running speed and a downward running speed of the piston have a 1.4- to 3-fold difference.
