Pistons for diesel engines

Pistons for diesel engines are thick-walled, high, with heavy bottom and bosses. They must retain functionality under high pressures in a cylinder and moderate rotational velocity of an engine arbor. To improve the resource, a piston can be filled with an insertion made of special type of cast iron (Ni-resistible), where one or two flutes are made. The combustion chambers located in the bottom of the piston have various shapes; can be coaxial with the skirt or produced with eccentricity. The resource of chamber edges can be improved by applying heat-resisting coating and supplying gallery oil cooling. The elliptidity of the skirt relative to the diameter is insignificant. The skirt can have antifriction or running-in coating.  The enterprise produces pistons for diesel engines from Ø95 mm (360.1004015) to Ø150 mm (51.03.40).
