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. There are certain requirements for the size of the components that set the water outlet. 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
[0022] The present invention will be described in further detail below in conjunction with the accompanying drawings.
[0023] Generally, the water-cooling structure of a motorcycle water-cooled engine includes a right crankcase cover 1, a cylinder block 2, a cylinder head 3, a cylinder head 4 and a cooling water pump. A cooling water pump installation cavity is arranged on the surface of the crankcase cover 1, and the cooling water pump is installed in the cooling water pump installation cavity. and sealed by the water pump cover 11, its overall structure see Figure 4 .
[0024] The present invention mainly relates to the improvement to cylinder head 4, see specifically Figure 1-3 On the lower surface of the cylinder head 4, there is a water inlet 41 of the cylinder head connected to the water outlet of the cylinder head. The water inlet 41 of the cylinder head communicates with the water outlet 43 on the side of the cylinder head and near the upper end of the cylinder hea...

The invention discloses an air cylinder cover for a motorcycle water cooled engine. A cylinder cover water inlet in butt joint with a cylinder head water outlet is formed in the lower surface of the air cylinder cover, and the cylinder cover water inlet is communicated with a water outlet nozzle on the side face of the air cylinder cover through a cooling runner in the air cylinder cover. The air cylinder cover is provided with the cooling runner, a circulation water path is prolonged, and the cooling effect can be improved better. The water outlet nozzle is arranged on the air cylinder cover, it is avoided that the water outlet nozzle is arranged on the air cylinder head and the water outlet nozzle has requirements for the size of the air cylinder head, and the air cylinder cover can be suitable for design of various engine cooling mechanisms. Water circulation additionally arranged on the air cylinder cover is beneficial to reducing the temperature of engine oil, and therefore the aims of reducing engine temperature and improving the lubricating conditions of all components are achieved.
Description
technical field [0001] The invention relates to motorcycle engine water cooling technology, in particular to a cylinder head for a motorcycle water cooling engine, 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 widely used...
