Claims

[Scope of claim for utility model registration] Water jacket 1 of single-cylinder horizontal engine 6
Open a hot water outlet 19b for cooling water at the top of the radiator 9, and a cold water inlet 19a at a lower part of the radiator 1.
Hot water inlet 10a at the top of 0, cold water outlet 1 at the bottom
0b, and connect the hot water outlet 19b of the water jacket 19 to the hot water inlet 10a of the radiator 10 via the flexible hot water pipe 46.
The cold water outlet 10b of the water jacket 19 is connected to the cold water inlet 19a of the water jacket 19 via a cold water pipe 47, and the cooling water absorbs heat in the water jacket 19, cools the cylinder 14 and the cylinder head 17, becomes high temperature water, and becomes hot water. In a horizontal engine water cooling system configured such that water passes through a pipe 46, radiates heat in the radiator 10, becomes low-temperature water, passes through a cold water pipe 47, and circulates to the water jacket 19. A radiator 10 is installed in the lateral outer space A of the cylinder head 17 located at
, the hot water inlet 10a of the radiator 10 is located close to the hot water outlet 19b of the water jacket 19, and the cold water outlet 10b of the radiator 10 is located close to the cold water inlet 19a of the water jacket 19, Cold water pipe 4 from cold water outlet 10b of radiator 10
Cold water inlet 19 of water jacket 19 via 7
A water pump 50 is interposed between the cylinder head 17 and the cylinder head 17 so that the water pump 50 pumps the low-temperature cooling water cooled by the radiator 10 from the radiator 10 to the water jacket 19. An outlet of the exhaust port 25 is opened in the upper surface 17a, an inlet of the intake port 22 is opened in the front surface 17b of the cylinder head 17, an exhaust pipe 26 is guided upward from the outlet of the exhaust port 25, and the upper end of the exhaust pipe 26 is opened. A water-cooled cooling device for a horizontal engine, characterized by a muffler 27 connected to the section.
