Stroke strong magnetic engine

The utility model discloses a stroke strong magnetic engine which comprises a shell, a piston, a crank shaft, a connecting rod and a power take-off mechanism linked with the crank shaft, wherein, the upper part of the piston is fixed with a mover iron core by bolts, a stator coil is arranged around the piston and is fixed on an insulation outer cover outside a shell by bolts, the crank shaft is provided with a cam, a rocker is arranged in the shell, one end of the rocker contacts with the cam, the shell is provided with an electrifying contact consisting of a dead point and a moving point, the dead point is connected with the stator coil, the moving point is connected with the positive pole of a power supply, the other end of the stator coil is connected with the negative pole of the power supply. The utility model is an improvement based on the prior monocylinder fuel engine or multi-cylinder fuel engine, does not change the power take-off mechanism linked with the internal crank shaft, mainly changes a driving mechanism at the piston, so the utility model has a simple structure and low cost. The utility model adopts the electromagnetic principle to allow the piston to work driven by the stator iron core, thereby driving the power take-off mechanism connected with the utility model to output the power, saving the energy, and having no pollution compared with the fuel engine.
