ABSTRACT:
The unitary cylinder head and liner combination, is vertically cast as a one piece unit. The liner incorporates a water jacket therein. The water jacket is draftless, allowing water to circulate therethrough more efficiently, increasing cooling capabilities. Such vertical one piece casting is made possible by a novel two piece core which eliminates the need for welding of metal bands onto an outer surface of the liner to produce the water jacket thereof. A novel method of vertical casting is also provided which allows the cylinder head to be cast integral with the liner, allows for increased water capacity in the liner and integral head passages, and allows for a plurality of enlarged air intake channels to be provided.
