Description
Technical field
The present invention relates to technical field of engines, in particular to a kind of motorcycle engine coolant circulation system and hair
Motivation.
Background technology
Engine cylinder body and cylinder cap collectively constitute power-transmitting part --- the shell of piston and bent axle, when engine does work
Will produce a large amount of heat, in order to by the heat from motor body（That is cylinder body and cylinder cap) discharge, need the cylinder in engine
Body and setting cooling passage in cylinder cap, so that coolant liquid flows through cylinder body and takes away heat with cylinder cap.
It is found in practice, coolant liquid flows into cylinder cap directly up after the cooling water channel that the cylinder body of engine enters cylinder sleeve
On cooling water channel in, then from outlet pipe flow out, flow velocity is very fast, short with the time of contact of cylinder sleeve and cylinder cap, heat exchanger effectiveness compared with
It is low, cause the heat dissipation performance of engine poor, finally be easy to cause piston scraping, reduces the service life of engine.
Invention content
In view of the above shortcomings of the prior art, the technical problem to be solved by the present invention is to：A kind of structure how is provided to set
Count ingenious, improvement cost is relatively low, can reduce the cooling liquid speed of available engine, improves heat exchanger effectiveness, improves engine
Heat dissipation performance, be conducive to extend the motorcycle engine coolant circulation system of the service life of engine, and a kind of dissipate
Good in thermal property, engine with long service life.
In order to solve the above-mentioned technical problem, present invention employs the following technical solutions：
A kind of motorcycle engine coolant circulation system, including gray iron and the cylinder sleeve on cylinder body, the cylinder
Also have around the circumferentially disposed jacket-cooling water road in a ring of the cylinder sleeve on body, the jacket-cooling water road extends upward through
The upper surface of the cylinder body；The side of the cylinder body is equipped with the water inlet being connected to the jacket-cooling water road；In the cylinder cap
With the Cooling of Cylinder Head water channel being arranged around combustion chamber, there is the multiple and Cooling of Cylinder Head water channel on the lower face of the cylinder cap
The precooling water channel of perforation, the precooling water channel along combustion chamber circumferentially, and under the assembled state of cylinder body and cylinder cap, with cylinder
Jacket water road face；The side of the cylinder cap is equipped with the water outlet being connected to the Cooling of Cylinder Head water channel；It is characterized in that, also
Include the cylinder cover sealing gasket between the cylinder body and cylinder cap, have on the cylinder cover sealing gasket it is multiple circumferentially
Water hole, projection of the water hole on vertical is located at the precooling water channel in the view field on vertical, and all institutes
The gross area for stating water hole is less than the gross area of all precooling water channels.
Using the above structure, coolant liquid is after water inlet enters jacket-cooling water road, using the mistake on cylinder cover sealing gasket
Water hole flows into Cooling of Cylinder Head water channel, finally from the water outlet outflow on cylinder cap.Since the gross area of all water holes is less than institute
The gross area for having precooling water channel flows into the flow velocity of Cooling of Cylinder Head water channel so as to slow down coolant liquid from jacket-cooling water road, has
It is come into full contact with conducive to coolant liquid and cylinder sleeve, coolant liquid and combustion chamber, ensures that coolant liquid fully carries out hot friendship with cylinder sleeve or combustion chamber
It changes, improves the heat dissipation performance of engine, avoid piston scraping, be conducive to extend the service life of engine.
Further, the water inlet is located at the side of the jacket-cooling water road radially, and is cooled down with the cylinder sleeve
The bottom of water channel is connected to；Using near the inlet opening of the water inlet, as starting point, the area of the inlet opening is along clockwise
Or counterclockwise gradually increase.
In this way, near water inlet water inlet hole area be exactly in all inlet openings it is minimum, coolant liquid passes through water inlet
After flowing into jacket-cooling water road, can not all be flowed into Cooling of Cylinder Head water channel from the inlet opening, only towards area bigger into
Water hole direction is flowed, to form the liquid stream around cylinder sleeve flowing in jacket-cooling water road, so that coolant liquid can fill
Divide and contacted with cylinder sleeve, and takes away the heat on cylinder sleeve.And coolant liquid is by water hole when entering Cooling of Cylinder Head water channel, due to every
The area of a inlet opening is different so that the cooling liquid speed in Cooling of Cylinder Head water channel is inconsistent, causes coolant liquid in Cooling of Cylinder Head
Flowing, avoids the formation of dead zone in water channel, is conducive to improve heat dissipation effect.
Further, projection of the precooling water channel on vertical is arc-shaped；The precooling water channel and the cylinder cap are cold
But there is the watercourse port of perforation setting, and the watercourse port is located at one of the precooling water channel in the circumferential direction of combustion chamber between water channel
End；Each precooling water channel is corresponding at least one water hole, and the corresponding water excessively of each precooling water channel
At least one of hole is located at the other end that the precooling water channel deviates from the watercourse port in the circumferential direction of combustion chamber.
In this way, coolant liquid by water hole flow into precooling water channel after, due to it is same precooling water channel corresponding to water hole
The both ends of cooling water channel are located at watercourse port so that the circumferential flow in water channel along combustion chamber can only be pre-chilled in coolant liquid,
Cooling of Cylinder Head water channel is entered via watercourse port again, coolant liquid can be come into full contact with, and take away burning by flowing with combustion chamber
The heat of room improves heat dissipation performance.
Further, the precooling water channel along the circumferential direction of combustion chamber it is uniformly distributed there are four, the adjacent precooling of two of which
The adjoining one end of water channel is close to chain chamber, and the respective watercourse port is respectively positioned on the end；Other two is adjacent described
The adjoining one end of precooling water channel is close to spark plug, and the respective watercourse port is respectively positioned on the end.
Further, the water channel open area on two precooling water channels of spark plug is less than close to chain chamber
Two it is described precooling water channels on the water channel open areas.
In this way, the cooling liquid speed in the precooling water channel of spark plug side can be made slower, fully heat is carried out with combustion chamber
It exchanges, improves heat dissipation performance.
Further, the inlet opening is less than the precooling water channel in combustion chamber radial direction in the size of the cylinder sleeve radially
On minimum dimension.
A kind of engine, which is characterized in that including above-mentioned motorcycle engine coolant circulation system.
In conclusion the motorcycle engine coolant circulation system of the present invention has smart structural design, improvement cost
It is relatively low, the cooling liquid speed of available engine can be reduced, heat exchanger effectiveness is improved, improves the heat dissipation performance of engine, favorably
In extend engine service life the advantages that.The engine of the present invention has many advantages, such as that perfect heat-dissipating, service life are long.
