Abstract

DC60 (26/01/53) Cylinder block integrated with the crankcase for combustion engines. A small interior is offered for added strength and stamina. Especially In order to reduce vibration and noise Cylinder section and crankcase section Will be made into a box-like shape that is cast into one piece, the crankcase cover will Pinned to the crankcase to cover the openings on its front and rear sides, the crank pad's pedals are equipped with crankcase slats arranged in the center. Of the back wall of the crankcase section to extend to both the inside and outside of the wall Rear for supporting the end of the crankshaft Where the ribs around the inside will be It is built along the corner where the back wall of the crankcase section is connected to the wall. The periphery that spanned from the periphery of the back wall. To crank inward from such an angle, the engine block structure is integrated with the crankcase for the combustion engine. Small interior is proposed to increase the stamina and stamina. Especially In order to reduce vibration and noise Cylinder section and crankcase section Will be made into a one-piece box-like shape, the crankcase cover will be Immobilized to the crankcase to cover the openings on its front and rear sides, the crankcase pad has a crank pad that is arranged in the center of the crankcase. The back wall of the crankcase section to extend to both the inside and outside of the side wall. Rear for supporting the end of the crankshaft Where the inner lateral ribs are formed Along the angle at which the back wall of the said crankcase section is connected to the wall. The periphery leading from the periphery of the back wall To cast inward from The corner.
