Abstract
PURPOSE:To almost equalize strains in each portion due to bending moment by internal pressure by making the thickness of the straight portion of a cylinder sleeve larger than that of the semicircle portion on both outsides of a piston for an engine provided with an oval piston. CONSTITUTION:In the inside of an oval form of a cylinder 1, consisting of the semicircle portions 1a on both outsides and the straight or slightly curved straight portion 1b between the semicircle portions 1a, almost the same shape of a piston 3 is fitted slidably through a cylinder sleeve 2. In such an internal combustion engine, the thickness of the straight portion in the middle of the cylinder sleeve 2 is made a comparatively large. Thus, in the straight portion 1b, a large sectional secondary moment is obtained and also in the semicircle portion 1a, a comparatively small sectional secondary moment is obtained. Therefore, strains in each portion due to the variation in bending moement by internal pressure can be made almost uniform, permitting seizure, etc., to be prevented.
