ABSTRACT:
A piston includes an insert, such as a piston ring insert or crown insert. In order to prevent the insert springing off the piston body in an axial direction, the insert is so formed with a recess or recesses which interlock with projections on the piston body so that the mechanical interlock between them holds the insert securely on the piston body. Further interlocking recesses and projections may be provided which are arranged to prevent relative rotation between the insert and the piston body.
