Claims

[Claims for Utility Model Registration] 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. Open the cold water outlet 10b and open the hot water outlet 19b of the water jacket 19.
Connect the hot water pipe 46 to the hot water inlet 10a of the radiator 10.
communicates with the cold water outlet 10 of the radiator 10 through
b is communicated with the cold water inlet 19a of the water jacket 19 via the cold water pipe 47, and the cooling water absorbs heat within the water jacket 19, cools the cylinder 14 and the cylinder head 17, becomes high temperature water, and flows through the hot water pipe 46. The heat is radiated by the radiator 10 and becomes low-temperature water, which passes through the cold water pipe 47 and enters the water jacket 1.

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,
A pump input wheel 51 is attached to a pump shaft 60 that protrudes backward from the pump case 58 of the water pump 50.
is fixed, a pump drive wheel 32a is fixed to a rotating shaft 29 protruding backward from the cylinder block 13, a pump input wheel 51 is interlocked and connected to the pump drive wheel 32a, and a rotor 71 of a generator 70 is connected to the pump input wheel 51. A water-cooled cooling system for a horizontal engine, characterized in that a stator 72 of a generator 70 is fixed to a pump case 58.
