Description
Technical field
The utility model relates to technical field of engines, in particular to a kind of motorcycle engine coolant circulation system
And engine.
Background technique
Engine cylinder body and cylinder cap collectively constitute power-transmitting part --- the shell of piston and crankshaft, when engine does work
A large amount of heat can be generated, in order to which the heat to be discharged from motor body (i.e. cylinder body and cylinder cap), needs the cylinder in engine
Cooling passage is set in body and cylinder cap, so that coolant liquid flows through cylinder body and cylinder cap takes away heat.
It is found in practice, coolant liquid flows into cylinder cap after the cooling water channel that the cylinder body of engine enters cylinder sleeve directly up
On cooling water channel in, then flow out of the water outlet pipe, 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.
Summary of the invention
In view of the above shortcomings of the prior art, the technical problem to be solved by the utility model is to how to provide a kind of knot
Structure is ingenious in design, and improvement cost is lower, can reduce the cooling liquid speed of available engine, improves heat exchanger effectiveness, improves hair
The heat dissipation performance of motivation is conducive to extend the motorcycle engine coolant circulation system of the service life of engine, Yi Jiyi
Kind perfect heat-dissipating, engine with long service life.
In order to solve the above-mentioned technical problem, the utility model uses the following technical solution:
A kind of motorcycle engine coolant circulation system, including gray iron and the cylinder sleeve being mounted on cylinder body, institute
Stating on cylinder body also has around the jacket-cooling water road in a ring of the cylinder sleeve being circumferentially arranged, and the jacket-cooling water road is 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；The cylinder
Lid is interior to have the Cooling of Cylinder Head water channel around combustion chamber setting, has the multiple and Cooling of Cylinder Head on the lower end surface of the cylinder cap
The pre-cooling water channel of water channel perforation, the pre-cooling water channel along combustion chamber circumferentially, and under the assembled state of cylinder body and cylinder cap,
With jacket-cooling 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；Its feature exists
In, further include the cylinder cover sealing gasket being mounted between the cylinder body and cylinder cap, have on the cylinder cover sealing gasket it is multiple circumferentially

Flow into jacket-cooling water road after, can not all from the inlet opening flow into Cooling of Cylinder Head water channel in, only towards area it is bigger into
Water hole direction flowing, so that the liquid stream around cylinder sleeve flowing is formed 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 by water hole enter Cooling of Cylinder Head water channel when, 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, the projection of the pre-cooling water channel vertically is arc-shaped；The pre-cooling 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 pre-cooling water channel in the circumferential direction of combustion chamber between water channel
End；Each pre-cooling water channel is corresponding at least one described water hole, and the corresponding water excessively of each pre-cooling water channel
At least one of hole is located at the other end that the pre-cooling water channel deviates from the watercourse port in the circumferential direction of combustion chamber.
In this way, coolant liquid by water hole flow into pre-cooling water channel after, the water hole as corresponding to the same pre-cooling water channel
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 pre-cooling water channel along the circumferential direction of combustion chamber it is uniformly distributed there are four, the adjacent pre-cooling of two of them
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 pre-cooling 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 pre-cooling water channels of spark plug is less than close to chain chamber
Two it is described pre-cooling water channels on the water channel open areas.
In this way, the cooling liquid speed in the pre-cooling water channel of spark plug side can be made slower, heat sufficiently is carried out with combustion chamber
Exchange improves heat dissipation performance.
Further, the inlet opening is less than the pre-cooling 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 utility model has smart structural design, transformation
Cost is relatively low, can reduce the cooling liquid speed of available engine, improves heat exchanger effectiveness, improves the heat dissipation performance of engine,
The advantages that being conducive to extend the service life of engine.The engine of the utility model has perfect heat-dissipating, long service life
The advantages that.
