Abstract
The utility model discloses a kind of engine fuel pipe, including fuel oil tube body, the inner wall along fuel oil tube body is circumferentially additionally provided with metal mesh.Since diesel oil belongs to immersion liquid for metal; therefore after engine is shut down; according to capillarity principle; diesel oil can keep certain height in fuel pipe; when air is entered by the seal clearance of the elements such as injection pump, filter, electrically operated fuel pump in fuel pipe; stopped by diesel oil in fuel pipe, air would not form bubble or air column in fuel pipe, to ensure that the normal operation of engine.The invention also discloses a kind of engines.
Description
Technical field
The utility model is related to technical field of engines, more particularly to a kind of engine fuel pipe and engine.
Background technology
After diesel engine is shut down, under gravity, the diesel oil in low pressure pipe returns to fuel tank, and air passes through spray
The seal clearance of the elements such as oil pump, filter, electrically operated fuel pump enters in fuel pipe, and bubble or air column are formed in oil pipe,
Engine is caused to be again started up difficulty.
Therefore, how a kind of engine fuel pipe is provided, enters air after avoiding engine from shutting down in fuel pipe, ensures hair
Motivation can run well the technical issues of being those skilled in the art's urgent need to resolve.
Utility model content
In view of this, the purpose of this utility model is to provide a kind of engine fuel pipe, engine can be effectively avoided
Enter air after shutdown in fuel pipe, ensures normal working of engine.
The another object of the utility model, which also resides in, provides a kind of engine.
To achieve the above object, the utility model provides the following technical solutions：
A kind of engine fuel pipe, including fuel oil tube body, the inner wall along the fuel oil tube body are circumferentially additionally provided with gold
Belong to net.
Preferably, the metal mesh is 2, and is arranged close to the both ends of the fuel oil tube body.
Preferably, the metal mesh is made of stainless steel.
Preferably, the mesh diameter of the metal mesh is less than 0.5mm.
Preferably, the inner wall of the metal mesh and the fuel oil tube body is fixedly linked.
A kind of engine, including engine fuel pipe, the engine fuel pipe are the hair as described in above-mentioned any one
Motivation fuel pipe.
As can be seen from the above technical solutions, engine fuel pipe disclosed in the utility model, including fuel oil tube body,
Inner wall along fuel oil tube body is circumferentially additionally provided with metal mesh.Since diesel oil belongs to immersion liquid for metal,
After engine is shut down, according to capillarity principle, diesel oil can keep certain height in fuel pipe, when air passes through oil spout
When the seal clearance of the elements such as pump, filter, electrically operated fuel pump is entered in fuel pipe, stopped by diesel oil in fuel pipe,
Air would not form bubble or air column in fuel pipe, to ensure that the normal operation of engine.
Description of the drawings
In order to illustrate the embodiment of the utility model or the technical proposal in the existing technology more clearly, below to embodiment or
Attached drawing needed to be used in the description of the prior art is briefly described, it is clear that, the accompanying drawings in the following description is only
The embodiments of the present invention without creative efforts, may be used also for those of ordinary skill in the art
To obtain other attached drawings according to the attached drawing of offer.
Fig. 1 is the structural schematic diagram of engine fuel pipe disclosed in an embodiment of the present invention.
Wherein, the title of each component is as follows：
1- fuel oil tube bodies, 11- metal meshes.
Specific implementation mode
In view of this, the core of the utility model is to provide a kind of engine fuel pipe, engine can be effectively avoided
Enter air after shutdown in fuel pipe, ensures normal working of engine.
Another core of the utility model, which also resides in, provides a kind of engine.
In order to make those skilled in the art more fully understand the utility model, below in conjunction with the accompanying drawings and it is embodied
The utility model is described in further detail for mode.
As shown in Figure 1, the engine fuel pipe disclosed in the utility model embodiment, including fuel oil tube body 1, along fuel oil
The inner wall of tube body 1 is circumferentially additionally provided with metal mesh 11.Since diesel oil belongs to immersion liquid for metal, when hair
Motivation shut down after, according to capillarity principle, diesel oil can keep certain height in fuel pipe, when air by injection pump,
When the seal clearance of the elements such as filter, electrically operated fuel pump is entered in fuel pipe, stopped by diesel oil in fuel pipe, air
Bubble or air column would not be formed in fuel pipe, to ensure that the normal operation of engine.
It is to be understood that capillarity refers to liquid on the inside of thin tube-like object, due to cohesive force and adhesive force
Difference, the phenomenon that overcoming centrifugal force and rising.Capillary is inserted into immersion liquid, and intraluminal fluid face rises, outer higher than pipe, capillary
Pipe is inserted into not immersion liquid, and liquid in pipe declines, less than the phenomenon outside pipe.For example, towel absorbs water, underground water rises along soil
All it is capillary phenomenon.A drop water silver is put on clean glass plate, it can roll over without adhering on a glass.One
The glass plate of block cleaning, which immerses in mercury to further take out, to be come, also non-cohesive mercury on glass.This liquid is non-cohesive in the surface of solids
On phenomenon be called and do not infiltrate.For glass, mercury is not immersion liquid.
It should be noted that metal mesh 11 is preferably provided with 2, and is positioned close to the end positions of fuel oil tube body 1, such as
This setting, it is ensured that diesel oil few as possible enters in fuel pipe.
Certainly, metal mesh 11 can be made of materials such as aluminium, iron, steel, since stainless steel is corrosion-resistant, high temperature resistant, energy
Enough prolong the service life, preferred metal mesh 11 is made of stainless steel in the utility model embodiment.
In order to advanced optimize above-described embodiment, the mesh diameter of metal mesh 11 is preferably smaller than 0.5mm, can effectively enhance
The adhesive force of metal mesh 11 forms bubble or air column to further avoid air in fuel pipe, influences engine again
Smoothly start.
It should be noted that metal mesh 11 and the inner wall of fuel oil tube body 1 are preferably fixedly linked, certainly, metal mesh 11 can
To be weldingly connected with fuel oil tube body 1, can also bond connected.
The utility model embodiment also discloses a kind of engine, including engine fuel pipe, and engine fuel pipe is such as
Engine fuel pipe disclosed in above-mentioned any one embodiment.
Since the engine uses the engine fuel pipe disclosed in above-described embodiment, which has both above-mentioned
The technical advantage of engine fuel pipe disclosed in embodiment no longer repeats this in present specification.
Each embodiment is described by the way of progressive in this specification, the highlights of each of the examples are with other
The difference of embodiment, just to refer each other for identical similar portion between each embodiment.
The foregoing description of the disclosed embodiments enables professional and technical personnel in the field to realize or use this practicality new
