ABSTRACT:
A method of making an engine block for an internal combustion engine comprising making an engine block with cylinder bores, forming a spray-formed cylinder liner with a predetermined internal diameter and a predetermined external diameter, heating the cylinder block, inserting the cylinder liner in the bore, and permitting the cylinder block to cool such that the liner is locked in position in the bore by compressive forces. The spray-formed cylinder liner comprises a cylindrical body made of a material having predetermined thermal characteristics, wear resistant and scuff resistant materials. The cylindrical body has an external surface formed by spray forming and an internal surface formed by spray forming. The liner can have a single spray-formed layer or multiple spray-formed layers of different materials.
