Problems solved by technology
The disadvantages of this engine water-cooled structure are: 1. Water passes through the cylinder surface, and under high temperature conditions, it is easy to cause the cylinder head gasket to be ablated, which will cause circulating water to enter the engine and cause the engine to fail.
2. If the size of the cylinder head is small, it is not conducive to the arrangement of the water outlet of the cylinder head
In view of the above factors, as well as the high cost of water-cooled engines, the application and promotion of water-cooled engines are restricted to a certain extent.

Embodiment Construction
[0026] The present invention will be described in further detail below in conjunction with the accompanying drawings.
[0027] Motorcycle water-cooled engine water-cooling structure of the present invention, its overall structure sees Figure 4 , including (right) crankcase cover 1, cylinder block 2, cylinder head 3, cylinder head 4 and the cooling water pump. A cooling water pump installation cavity is provided on the surface of the crankcase cover 1. The cooling water pump is installed in the cooling water pump installation cavity and passes through the water pump Cover 11 is sealed. A circulating water cavity 21 is arranged in the cylinder body 2 , and the circulating water cavity 21 is connected with the water pump cover 11 through the engine water pipe 5 . See Figure 6 , A water hole 22 communicating with the circulating water chamber is provided on the upper surface of the cylinder block 2 . see Figure 7-9 , the inside of the cylinder head 3 is provided with a wate...

The invention discloses a water cooling structure of a motorcycle water cooling engine. A circulation water cavity in an air cylinder body is connected with a water pump cover on a crank case cover through an engine water pipe. Water passing holes are formed in the upper surface of the air cylinder body. A water cavity runner is arranged in an air cylinder head. Water passing holes which are communicated with the water cavity runner and correspond to the water passing holes in the upper surface of the air cylinder body are formed in the lower surface of the air cylinder head. A cylinder head water outlet is formed in the upper surface of the air cylinder head, and a cylinder cover water inlet in butt joint with the cylinder head water outlet is formed in the lower surface of the air cylinder cover. The cylinder cover water inlet is communicated with an air cylinder cover water outlet nozzle through a cooling runner, and the water outlet nozzle is connected with a radiator through a water pipe. Circulation water only passes the water passing holes in the periphery of the air cylinder body and the periphery of the air cylinder head, and burning down of an air cylinder gasket due to the high temperature is avoided. The water outlet nozzle is arranged on the air cylinder cover, the temperature of oil can be reduced through water circulation, and therefore the purposes of reducing the temperature of the engine and improving the lubricating condition of components are achieved.
Description
technical field [0001] The invention relates to a water-cooled engine of a motorcycle, in particular to a water-cooled structure of a water-cooled engine of a motorcycle, and belongs to the technical field of engine cooling. Background technique [0002] In recent years, with the implementation of the national rich peasant policy and the western development strategy, three-wheeled motorcycles have become a good helper for farmers to make a fortune, and they are also increasingly developing in the direction of large displacement. The continuous increase of displacement, coupled with the harsh environment of the engine (heavy load, poor road conditions, poor user maintenance), high engine temperature, crankshaft big end locked, piston scuffing, burning oil and other faults also increase. Bring very bad negative influence to the popularization of large-displacement tricycle engine. In order to solve such problems, water-cooled engines with better cooling effects have been wi...
