EXOTHERMIC BONDING FOR CYLINDER BLOCK INSERTS

摘要

A method for manufacturing an engine block is disclosed. In embodiments, the method includes forming an expansion hole in a block body of the engine block that encircles an engine block bore at a head face of the engine block. The method also includes placing an insert into the expansion hole, the insert including an insert body. The method further includes placing a reaction material between the insert and the block body. The method yet further includes forming an insert bond layer between the insert and block body using the reaction material. The method still further includes forming an insert bore through the insert body.
