Abstract
A V-engine includes angularly oriented cylinder banks with an outer enclosing rectangular cooling jacket wall and outwardly opening cylinders closed by an outer cylinder head. Bolt attaching lugs are integrally formed on the exterior of the cylinder walls within the cooling chamber and are spaced from the jacket wall to maintain a continuous cooling passageway. The head is bolted to the cylinder block at such lugs. The inner and outer vertical edges of the head are beveled with the outer edge reducing the overall width and inner edge increasing the spacing between the cylinder banks.
Claims8
In an internal combustion engine having a V-block defining a pair of cylinder banks with a plurality of cylinders arranged as in-line cylinders in each bank, each of said cylinders having an outer sidewall and being closed by a separate cylinder head, each of said cylinder banks having an outer cooling jacket wall encircling said cylinders in the bank and spaced from the cylinder sidewalls for defining a separate cooling chamber about said cylinders in each bank, said separate cylinder head overlying each bank and closing the cylinders and the cooling chamber, said separate head providing the only closure of said cylinder and said cooling chamber, head attachment means secured to said sidewalls for securing of the head to the cylinder bank within the corresponding cooling chamber in inwardly spaced relation to the corresponding jacket wall whereby each of the cooling chambers extends around said head attachment means and provides coolant flow around the head attachment means, said heads having the outer side edges beveled to reduce the width of the engine.
