Claims

[Claims for Utility Model Registration] 1. A hot water outlet 19b for cooling water is provided in the upper part of the water jacket 19 of the horizontal engine 6, a cold water inlet 19a is provided in a lower part thereof, a hot water inlet 10a is provided in the upper part of the radiator 10, and a hot water inlet 10a is provided in the lower part of the water jacket 19 of the horizontal engine 6. cold water outlet 10b
Open the hot water outlet 19 of the water jacket 19.
b to hot water pipe 4 to hot water inlet 10a of radiator 10.
6 and communicates with the cold water outlet 1 of the radiator 10.
0b to cold water inlet 19a of water jacket 19
The cooling water absorbs heat in the water jacket 19 and cools the cylinder 14 and cylinder head 17 to become high-temperature water, passes through the hot water pipe 46, radiates heat through the radiator 10, and becomes low-temperature water. In a water-cooled cooling system for a horizontal engine configured to circulate cold water to the water jacket 19 through the cold water pipe 47, the water pump 50 is supported on the upper wall 20a of the water jacket 19, and the water pump 50 is supported on the upper wall 20a of the water jacket 19.
The inlet 50a of the water jacket 19 is connected to the hot water outlet 19b of the water jacket 19, and the hot water pipe 46 is connected to the discharge port 50b of the water pump 50.
The high temperature cooling water heated by the water jacket 19 is pumped to the water jacket 1 by the water pump 50.
9 to the radiator 10, and an air vent 7 is provided at the top of the water jacket 19.
0, the air vent port 70 is configured to be able to communicate with and shut off from the atmosphere via an air vent valve 72, and the hot water outlet 19b is located below the air vent port 70 within the water jacket 19. water-cooled cooling system for horizontal engines. 2. The air vent valve 72 is configured to be open/close controlled by the engine stop detection means 74, and the air vent valve 72 is opened for a set time based on the engine stop detection means 74 detecting that the engine 6 has stopped. A water-cooled cooling device for a horizontal engine according to claim 1 of the utility model registration.
