Description
Technical Field
The utility model belongs to the field of engines, and particularly relates to a small-circulation cooling water path structure of an engine.
Background
In the process of small circulation of a traditional engine, the cooling water circulation flow is large, the quantity of heat taken away is large, the engine cannot reach normal working temperature quickly, fuel in an engine cylinder is not completely combusted, engine oil consumption and emission indexes are deteriorated, and more engines adopt the scheme that small circulation is arranged at the front end. However, the existing scheme has a complex structure and air in a water path is difficult to discharge, so that the cost of the engine is high, the small-cycle function fails, and the performance of the engine is reduced.
Disclosure of Invention
In order to overcome the problems in the prior art, the utility model provides a small-circulation cooling water channel structure of an engine, wherein a water flow channel is arranged on a cylinder cover and a machine body, a water jacket of the cylinder cover is communicated with a thermostat cavity, and an exhaust port is arranged at the tail end of the channel of the cylinder cover, so that air in the water channel can be better exhausted.
In order to realize the purpose, the utility model is realized by the following technical scheme:
the small-circulation cooling water path structure of the engine comprises the following characteristics:
a cylinder cover and a machine body of the engine are internally provided with a circulating cooling water channel for communicating a cylinder cover water jacket with a thermostat cavity; and the circulating cooling water channel is provided with an exhaust port communicated to the outside of the cylinder cover.
Preferably, the circulating cooling water channel comprises a small circulating channel A, a small circulating channel B, a cavity, a small circulating channel D and a small circulating channel E, wherein the small circulating channel A is transversely arranged at the front end of the cylinder cover and communicated with the water jacket of the cylinder cover; the small circulation channel A, the small circulation channel B, the small circulation channel C, the small circulation channel D, the small circulation channel E and the thermostat cavity are communicated in sequence; the exhaust port is communicated with the small circulation passage A.
Preferably, the tail end of the exhaust port is provided with a detachable plug.
Preferably, a sealing gasket is arranged between the cavity and the machine body.
The utility model has the beneficial effects that:
according to the utility model, the water flow channel is arranged on the cylinder cover and the engine body, the cylinder cover water jacket is communicated with the thermostat cavity, the exhaust port is arranged at the tail end of the cylinder cover channel, so that air in a water channel can be exhausted better, the structure is simple, the design is reasonable, the number of parts of a small circulation system can be reduced, and the performance of an engine is ensured.

FIG. 1 is a schematic structural view of the present invention;
in the figure, 1-cylinder cover water jacket, 2-small circulation channel A, 3-exhaust port, 4-small circulation channel B, 5-small circulation channel C, 6-small circulation channel D, 7-small circulation channel E, 8-cylinder cover, 9-engine body, 10-thermostat cavity and 11-sealing gasket.
Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings to facilitate understanding of the skilled person.
As shown in fig. 1, the small circulation cooling water path structure of the engine comprises a circulation cooling water channel which is arranged in a cylinder head 8 and a machine body 9 and is communicated with a cylinder head water jacket 1 and a thermostat cavity 10.
The circulating cooling water channel comprises a small circulating channel A2, a small circulating channel B4, a cavity, a small circulating channel D6 and a small circulating channel E7, wherein the small circulating channel A2 is transversely arranged at the front end of the cylinder cover 8 and communicated with the cylinder cover water jacket 1; the small circulation channel A2, the small circulation channel B4, the small circulation channel C5, the small circulation channel D6, the small circulation channel E7 and the thermostat cavity 10 are communicated in sequence.
Through setting up the circulative cooling water course that communicates at cylinder head water jacket 1 and thermostat cavity 10, reducible cooling water circulation flow reduces the heat of taking away, guarantees that the engine can reach normal operating temperature fast, guarantees engine performance.
The small circulation channel A2 is provided with an exhaust port 3 communicated to the outside of the cylinder cover, the tail end of the exhaust port 3 is provided with a detachable plug, when the exhaust is needed, the plug is opened to exhaust, and the plug is in a normally closed state. The exhaust port 3 is positioned at the highest point of the cylinder head water jacket 1, and can effectively exhaust gas in the engine water jacket.
Gas in the cooling water can be discharged through arranging the gas exhaust port 3, the cooling effect of the cooling water is guaranteed, and the heat exchange efficiency of the cooling water due to excessive influence of the gas in the cooling water is avoided.
A sealing gasket 11 is arranged between the cavity and the machine body 9 to prevent a small circulation channel C5 enclosed by the cavity and the machine body 9 from leaking water.
Finally, it is noted that the above-mentioned preferred embodiments illustrate rather than limit the utility model, and that, although the utility model has been described in detail with reference to the above-mentioned preferred embodiments, it will be understood by those skilled in the art that various changes in form and detail may be made therein without departing from the scope of the utility model as defined by the appended claims.
