TECHNOLOGICAL PECULIARITIES OF PRODUCTION OF PISTONS FOR HIGH-POWERED ENGINES

Abstract

The paper present the results obtained when investigating fabrication of castings for pistons of high-augmented diesel internal combustion engine. The optimum casting parameter ranges are determined. The development is made of piston construction with combined insert that ensures production of castings of high-loaded pistons with a cavity (gallery) for oil cooling of upper piston ring zone and enhancement of installation zone of upper piston ring.
