気筒エンジンにおけるシリンダの冷却構造。 A cooling liquid groove is formed on the outer peripheral surface of the liner, and when this liner is inserted into the bore of the cylinder block, a space defined by the inner peripheral surface of the bore of the cylinder block and the groove forms a cooling liquid flow path, The cylinder is cooled by flowing the coolant into this coolant flow path.
In a cooling structure for a cylinder in a multi-cylinder engine, the cross-sectional area of the coolant flow path is continuously or intermittently moved from a portion disposed on the axis of the crankshaft to a portion making 90 degrees thereto in the circumferential direction. A cylinder cooling structure in a multi-cylinder engine, which is characterized by its increased size.
