    摘要: An overhead-valve type forcedly air-cooled engine has a cylinder jacket (17) for cooling part of its cylinder (24), provided in a partition wall (16) between the cylinder and its push rod chamber (18) in order to solve a problem such as thermal distortion of the cylinder. A portion of the lubricating oil delivered from an oil pump (10) in a forced lubrication system employed in the engine serves to cool only the partition wall (16) which forms part of the periphery of the cylinder (24) during passing through the cylinder jacket (17).

    摘要: Simplifying a water circulation structure of a cylinder block and realizing a compact layout of piping connecting an engine body and a radiator.
    A water-cooled internal combustion engine (E) is provided with an engine body including a cylinder block (20) and a cylinder head (21), and a radiator (52). The radiator (52) is disposed separated, in a prescribed direction, i.e. in a rightward direction, from the engine body. A chain chamber (44) which accommodates a transmission mechanism, including a chain, for a valve system is provided in end portions (20e and 21e), which are located rightwardly toward the radiator (52), of the cylinder block (20) and the cylinder head (21), respectively. A cooling water outlet portion (61) open to a cylinder head water jacket (Jh) is provided in the end portion (21e) of the cylinder head (21), the cooling water outlet portion (61) being connected with an inlet pipe (57) for leading the cooling water having flowed out of a cylinder block water jacket into the cylinder head water jacket Jh to the radiator (52). The cooling water outlet portion (61) is disposed rightwardly closer to the radiator (52) than the chain chamber (44).

    摘要: In a cooling system structure for a vehicular water-cooled internal combustion engine (E) with a cylinder section and a cylinder body (41) and a cylinder head (42). The cooling system structure having water jackets (50A) formed in the cylinder body (41) and the cylinder head (42), respectively, with a radiator (52) disposed forwardly of the engine main unit. A water pump performs forced circulation of coolant through the radiator (52) and the water jackets (50A), to permit routing of pipes with enhanced appearance. Water jackets (50A) are formed, respectively, in a cylinder body (41) and a cylinder head (42) such that coolant flows through the cylinder body (42) and the cylinder head (42) independently of each other. A thermostat is mounted on a front wall surface of a cylinder section and is capable of selecting a condition in which the water jackets (50A) directly communicate with each other or a condition in which the water jackets (50A) communicate with each other via a radiator (52).
