FIELD: engines and pumps.
SUBSTANCE: invention relates to repair and can be used for recovery of worn-out surface of ICE cylinder liners. Proposed method comprises placing the mandrel with liner to be recovered into sealed chamber and squeezing of said liner by radial forces applied to its cylindrical surface over said mandrel. Water-filled discharge chamber is used with its inner cavity composed by two aligned conical surfaces, their axes being aligned with electric discharge channel geometrical axis. Note here that liner squeezing over mandrel fitted therein is carried out by the energy of electrohydraulic shock with blast wave focused effects.
EFFECT: uniform squeezing in radial direction without tempering, increased percentage of reuse of liners.
