Belong to engine cool technical field.
Background technology
In recent years, as the implementation of national rich peasant's policy and strategy to develop western regions, motor tricycle turn into friend peasant
The good assistant that friend builds up the family fortunes, and also increasingly develop to huge discharge direction.Discharge capacity is continuously increased, and engine is severe in addition
Use environment（Heavy duty, road conditions are poor, user maintaining is poor）, engine temperature height, the locking of bent axle major part, piston scraping,
The various failures such as burn oil are consequently increased, and the popularization to huge discharge tricycle engine brings very bad negative effect.For
Solution problems, the more preferable water-cooled engine of cooling effect are widely used in tricycle.
Traditional Water-cooled engine cylinder water jacket is circle ring column water channel 26（Such as Fig. 1）, corresponding cylinder head cylinder face
The bar shaped tank 34 on same circumference that quantity does not wait is designed with, sees Fig. 2, recirculated water enters cylinder head by bar shaped tank
Internal water cavity, then by water cavity inside cylinder head from cylinder head delivery port 35（See Fig. 3）Flow out into radiator circulation.It is this
The shortcomings that engine water air-cooled structure is：1st, water passes through from cylinder face, cylinder head sealing gasket ablation is easily caused under hot conditions, so as to draw
Recirculated water is played to enter engine and cause power failure.If the 2, cylinder area of bed is smaller, it is unfavorable for cylinder head delivery port
Arrangement.In view of above-mentioned factor, and the problem of water-cooled engine cost itself is high, water-cooled engine is constrained to a certain extent
Using and promote.
The content of the invention
For deficiencies of the prior art, it is an object of the invention to provide a kind of before water-cooled effect is ensured
Put, can avoid because high temperature burns out the cooling engine for motor cycle water water-cooling structure of head gasket.
To achieve these goals, the technical solution adopted by the present invention is such：
