Cylinder block cooling jacket insert allowing separated cooling circuits

Abstract

A number of variations may include at least one insert that may have a concave surface, a convex surface, a first and second side surface, a top surface, and a bottom surface. The insert may be disposed within the cooling jacket of the engine block and may define a first and a second cooling jacket portion. The insert may allow for fluid communication between the first and second cooling jacket portions.

1 . A product comprising:
 at least one cooling jacket for an engine block cooling jacket comprising an insert comprising a concave surface, a convex surface, a first and second side surface, a top surface, and a bottom surface wherein the concave surface and the convex surface are juxtaposed such that the curve of the convex surface follows a curve similar to that of the concave surface, or vice versa.   
     
     
         2 . The product as set forth in  claim 1 , wherein:
 the at least one insert may define at least one through hole.   
     
     
         3 . The product as set forth in  claim 1 , wherein:
 the at least one insert defining at least one feed outlet in the top surface.   
     
     
         4 . The product as set forth in  claim 1 , further comprising:
 a cooling jacket insert assembly comprising at least one insert.   
     
     
         5 . The product as set forth in  claim 1 , wherein:
 the product further comprises a cooling jacket insert assembly that comprises the at least one cooling jacket insert, and wherein the at least one cooling jacket insert comprises one or more inserts arranged side by side and connected by one or more tie bands fixing each individual insert to one or more adjacent inserts.   
     
     
         6 . A product comprising:
 a cooling jacket insert assembly and an engine cylinder block;   the engine cylinder block comprising a plurality of cylinder bores, a coolant outlet, and a cooling jacket;   the cooling jacket surrounding at least a portion of the plurality of cylinder bores;   the cooling jacket insert assembly comprising at least one insert and being constructed and arranged to divide the cooling jacket into a first cooling jacket portion not adjacent the plurality of cylinder bores and a second cooling jacket portion adjacent the plurality of cylinder bores; and   the at least one insert comprising a concave surface, a convex surface, a first and second side surface, a bottom surface, and a top surface.   
     
     
         7 . The product as set forth in  claim 6 , wherein:
 the at least one insert defines one or more through holes in the concave surface and the convex surface; and   the one or more through holes being constructed and arranged to allow fluid communication between the first cooling jacket portion to the second cooling jacket portion and to the coolant outlet and vice versa.   
     
     
         8 . The product as set forth in  claim 6 , wherein:
 the top surface defines one or more feed outlets; and   the one or more feed outlets being constructed and arranged to allow a fluid communication between the one or more feed outlets out of the first cooling jacket portion or the second cooling jacket portion or both.   
     
     
         9 . A method comprising:
 providing an engine cylinder block;   the engine cylinder block comprising a plurality of cylinder bores, a plurality of cylinder heads, a coolant outlet, and a cooling jacket;   the cooling jacket surrounding at least a portion of the plurality of cylinder bores;   providing a cooling jacket insert assembly;   the cooling jacket insert assembly comprising at least one insert and being constructed and arranged to divide the cooling jacket into a first cooling jacket portion not adjacent the plurality of cylinder bores and a second cooling jacket portion adjacent the plurality of cylinder bores;   the at least one insert comprising a concave surface, a convex surface, a first and second side surface, a bottom surface, and a top surface;   disposing the cooling jacket insert assembly within the cooling jacket of the engine cylinder block; and   dividing the cooling jacket into a first cooling jacket portion and a second cooling jacket portion.   
     
     
         10 . A method as set forth in  claim 9 , wherein:
 the at least one insert defines one or more through holes in the concave surface and the convex surface;   the one or more through holes being constructed and arranged to allow fluid communication between the first cooling jacket portion to the second cooling jacket portion and to the coolant outlet and vice versa.   
     
     
         11 . A method as set forth in  claim 9 , wherein:
 the top surface defines one or more feed outlets;   the one or more feed outlets being constructed and arranged to allow fluid communication between the one or more feed outlets into the first cooling jacket portion or the second cooling jacket portion or both.
