The piston of this engine are made of right hand aluminum with good heat resistance and thermal conductivity parameters. The combustion chamber is not divided, ω-shaped, made by a groove in the piston preparation. The use of a combustion chamber of this shape, as well as optimization of the nozzle spray pattern, made it possible to reduce the noise of the combustion process and the toxicity of exhaust gases by improving the combustion process. The piston skirt is coated with a special coating that serves to reduce the friction of the piston against the cylinder walls.
