ABSTRACT:
The unitary cylinder liner incorporating a water jacket is vertically cast as a one piece unit. The water jacket is draftless, allowing water to circulate therethrough more efficiently, increasing cooling capabilities. Such vertical one piece casting is made possible by the novel two piece core which eliminates the need for welding of metal bands onto an outer surface of the liner to produce the water jacker thereof. A novel method of vertical casting is also provided by use of the two piece core.
