Description
Technical field
The present invention relates to motorcycle engine Water Cooling Technology, in particular to a kind of cooling engine for motor cycle water cylinder
Lid, belongs to engine cool technical field.
Background technique
In recent years, with the implementation of national rich peasant's policy and strategy to develop western regions, motor tricycle has become 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 maintenance is poor), engine temperature height, the locking of crankshaft major part, piston scraping,
The various failures such as burn oil are consequently increased, and bring very bad negative effect to the popularization of huge discharge tricycle engine.For
Solution problems, the better water-cooled engine of cooling effect are widely used in tricycle.
Traditional Water-cooled engine cylinder water jacket is circle ring column water channel, and the design of corresponding cylinder head cylinder face has quantity
The not equal bar shaped sink being located on same circumference, recirculated water enters water cavity inside cylinder head by bar shaped sink, then passes through gas
Water cavity flows out into radiator circulation from cylinder head water outlet inside cylinder head.The shortcomings that this engine water air-cooled structure, is: 1,
Water passes through from cylinder face, cylinder head sealing gasket ablation is easily led under hot conditions, so as to cause recirculated water enters engine and causes
Power failure.2, there is certain requirement to the part dimension of setting water outlet, if cylinder area of bed is smaller, be unfavorable for cylinder
The arrangement of head water outlet.3, since there are circulation machine oils in cylinder head, and the water-cooling structure cooling water is discharged by cylinder head,
Not over cylinder head, it is unfavorable for the decline of cylinder head and circulation machine oil temperature.In view of above-mentioned factor and water-cooled engine sheet
Body problem at high cost constrains the application of water-cooled engine to a certain extent and promotes.
Summary of the invention
In view of the above shortcomings of the prior art, the purpose of the present invention is to provide a kind of cooling engine for motor cycle water use
Cylinder head, this cylinder head can participate in engine water SAPMAC method, so as to further increase water-cooled effect, and reduce cylinder head
And circulation machine oil temperature.
To achieve the goals above, the technical solution adopted by the present invention is that it is such:
A kind of cooling engine for motor cycle water cylinder head is equipped with the cylinder cap docked with cylinder head water outlet in cylinder head lower surface
Water inlet, cylinder cap water inlet are connected to by the coolant flow channel inside cylinder head with the faucet of cylinder head side.
Further, the coolant flow channel is vertically arranged the oil circulation channel simultaneously in cylinder head, in favor of to machine
Oil is cooled down.
The faucet is arranged obliquely, in favor of reducing resistance to water-flow.
Compared with prior art, the invention has the following advantages:
1, faucet is set in cylinder head, and cooling path is on the one hand arranged in cylinder head, extends circulation waterway, mentions
High cooling effect；On the other hand also be conducive to structure design because can to avoid be set to cylinder head on to cylinder head own dimensions
Requirement, therefore can be adapted for the design of various engine cool mechanisms.
2, water circulates through cylinder head organic oil circulation nearby, advantageously reduces oil temperature, starts to reach reduction
Machine temperature improves the purpose of each component lubrication condition.In addition, the reduction of cylinder head temperature is also beneficial to improve the driving of driver
Environment.
This structure improves less cylinder head, and improvement cost is low, conducive to the popularization of water-cooled engine.
