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 motorcycle water-cooling engine water-cooling structure. A circulating water cavity in a cylinder body is connected with a water pump cover on a crankcase cover through an engine water pipe. A water hole is arranged on the upper surface of the cylinder body; a water cavity flow channel is arranged inside the cylinder head, and a water hole communicated with the water cavity flow channel is arranged on the lower surface of the cylinder head and corresponds to the water hole on the upper surface of the cylinder block. The upper surface of the cylinder head is provided with a water outlet of the cylinder head, and the lower surface of the cylinder head is provided with a water inlet of the cylinder head connected with the water outlet of the cylinder head. Connect the radiator. The circulating water of the present invention only passes through the water holes on the periphery of the cylinder body and the cylinder head, and the cylinder gasket will not be burned due to high temperature. The water nozzle is set on the cylinder head, and the water circulation is beneficial to reduce the temperature of the engine oil, so as to achieve the purpose of reducing the engine temperature and improving the lubrication conditions of each component.
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 wide...
