| description | The utility model discloses a methanol piston structure for a methanol engine, which belongs to the field of methanol engine pistons, and comprises a piston head, one end of the piston head is rotatably connected with a connecting rod, the outer end of the piston head is provided with annular grooves, and the annular grooves comprise a gas annular groove and an oil annular groove. Oil outlets are evenly formed in the side end of the piston head, a distance ring is fixedly connected to the inner wall of the piston head, and the space between the inner wall of the distance ring and the inner wall of the piston head is filled with lubricating liquid. The moisture absorption cotton sprays oil outside the piston head through inertia in the moving process of the piston head, so that it is guaranteed that a layer of oil film is formed outside the piston head for a long time, the purpose of reducing friction loss of an engine is achieved, in addition, the sealing performance of the outside of the piston head is impro |
