The cylinder head (12) and liner (14) combination, is vertically cast as a one piece unit (10). The liner (14) incorporates a water jacket (16) therein. The water jacket (16) 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 (82) which eliminates the need for welding of metal bands onto an outer surface of the liner (14) to produce the water jacket (16) thereof. A novel method of vertical casting is also provided which allows the cylinder head (12) to be cast integrally with the liner (14), allows for increased water capacity in the liner and integral head passages (30, 42, 44), and allows for a plurality of enlarged air intake channels (20) to be provided.

Combinaison culasse (12) et garniture (14) coulée verticalement en tant qu'unité (10) d'un seul tenant. La garniture (14) comporte une chemise d'eau (16). Ladite chemise d'eau (16) est sans tirage, ce qui permet à l'eau de circuler à travers elle plus efficacement et augmente les capacités de refroidissement. Ce coulage vertical en une seule pièce est rendu possible par un nouvel élément central (82) en deux pièces qui élimine le besoin de souder des bandes de métal sur une surface externe de la garniture (14) pour produire la chemise d'eau (16). Un nouveau procédé de coulage vertical est également décrit. Ce procédé permet de couler d'un seul tenant la culasse (12) avec la garniture (14), permet une augmentation de la capacité d'eau dans la garniture et des passages (30, 42, 44) d'un seul tenant avec la culasse, et permet de ménager une pluralité de canaux (20) élargis d'admission d'air.
