Title: Cylinder block casting slab core cast geometry for sawcut entrance enhancement

Abstract

An automobile vehicle engine includes multiple water jackets individually formed in a cast engine block proximate to successive ones of multiple cylinder bores. Multiple cast-in place transition regions are individually formed during a casting operation of the cast engine block at entrances to individual ones of the multiple water jackets. Individual ones of multiple sawcuts open into individual ones of the multiple cast-in place transition regions.
