Cylinder block for an internal combustion engine

摘要

An improved cylinder block for a high compression internal combustion engine is provided which includes a cooling jacket having interconnected peripheral side and end walls and a base section, and at least one cylinder tube disposed within and encompassed by the jacket wall. The tube extends upwardly from and is connected to the jacket base section. The upper end portion of the tube adjacent the top surface of the block is reinforced by a plurality of substantially radial supports extending from the tube exterior to the interior surface of the jacket wall. The supports provide substantial radial reinforcement as compared to vertical reinforcement of the tube, particularly in the area thereof which is subjected to the greatest pressure during operation of the engine.
