Claims

[Scope of utility model registration request]

It consists of a head part with a ring groove provided in the side wall and a skirt part located under the head part, and inside the skirt part adjacent to the head part, there is a thermal expansion part of the skirt part. A piston is provided with a strut plate for preventing the piston, the strut plate is provided with a number of protrusions extending at an acute angle to the surface, and the strut plate is provided with a number of protrusions extending at an acute angle with respect to the surface. A piston for an internal combustion engine, characterized in that at least the protrusion is cast inside the skirt upper part and is attached to the inside of the skirt upper part, with the surface opposite to the surface on which the piston is provided exposed.
