| description | The utility model provides an engine piston, an engine and a vehicle. The engine piston comprises a piston head, a supporting wall provided with a piston pin seat and two piston skirts connected to the two sides of the supporting wall. The top of the piston head is provided with an air extrusion flow guide part which protrudes upwards relative to the upper reference surface of the piston head; the air squeezing flow guide part comprises two protrusions arranged on the two sides of the first axis respectively and a concave part located between the two protrusions. The first axis is perpendicular to the axis of a pin hole of the piston pin seat; the piston head comprises a plurality of ring lands, and a reinforcing piece extending from the piston skirt to the axis of the pin hole is arranged on the bottom face of the first ring land from bottom to top in the plurality of ring lands. By means of the engine piston, the problem that in the prior art, an engine piston with a protruding structure with a pit at the t |
