<P>PROBLEM TO BE SOLVED: To provide a liquid-cooled engine with cooling means, whereby ample cooling capacity can be ensured, while maintaining compactness. <P>SOLUTION: This liquid-cooled engine 10 with the cooling means includes the cooling means 43 for cooling an area surrounding a combustion chamber 49 by making a cooling liquid cooled by a radiator 16 flow through a cooling passage 54. The cooling passage 54 is embedded in a cylinder block/head 31 (a cylinder block 32 and a cylinder head 33). Further, the cooling passage 54 is formed in a unicursal fashion such that the cooling liquid is introduced from the radiator 16 to cool an area surrounding the combustion chamber 49, and thereafter returns to the radiator 16 by looping around an area surrounding an exhaust valve 52 for opening and closing an exhaust port 149 of the combustion chamber 49. <P>COPYRIGHT: (C)2012,JPO&INPIT |
