Abstract
A one-piece crankcase and cylinder block structure for V-type internal combustion engines is disclosed, which is formed by casing and comprises a crankcase with its one end wall side opened and a cylinder block including at least a pair of right and left cylinders opposed to each other at 90.degree.. The cylinders are formed to project at their skirt portion into inside of the crankcase forming a longitudinal space between the protruded ends of the skirt portions to house a camshaft. Another space is defined adjacent to the opened side of the crankcase between the protruded ends of the skirt portions to house a camshaft gear. Since the construction is such that, in casting, the directions in which the segments of mold and the cores are ejected from the casting are uniformly distributed, and the distance over which the cores and mold segments are ejected is greatly minimized. Thus, a relatively small casting machine can be employed to properly cast such a one-piece crankcase and cylinder block structure.
