Abstract
The invention relates to a vacuum air intake rubber hose for a diesel engine. The vacuum air intake rubber hose for the diesel engine comprises a rubber hose body. At least one deformation cavity is arranged on the rubber hose body along a length direction of the rubber hose body; the inner diameter of the deformation cavity is larger than the inner diameter of the rubber hose body; a bulge is formed at a position of the deformation cavity and on an outer wall of the rubber hose body; two ends of the bulge are respectively in circular arc smooth transition with the outer wall of the rubber hose body; an inner wall of the deformation cavity is of a circular arc structure; the inner wall of the deformation cavity and an inner wall of the rubber hose body are in circular arc smooth transition. By adopting the technical scheme, the tapered deformation cavity is arranged on a traditional equal-diameter rubber hose, so that the phenomenon that the rubber hose is shrunken when the rotation speed of a supercharger is fluctuated and the air intake pressure is reduced is effectively avoided; the fluctuation of the air intake amount of the engine is avoided, the performance stability of the engine is ensured, and the problem that the diesel engine flames out to shut off a car caused by the fluctuation of introduced gas is avoided. In addition, the vacuum air intake rubber hose can bear larger vibration, and especially the deformation of the axial tension is more superior compared with the traditional equal-diameter rubber hose.
Description
Technical field
The invention belongs to technological invention mechanism and make technical field, particularly relate to a kind of vacuum used for diesel engine and enter
Gas sebific duct.
Background technology
Vacuum gas inlet rubber tube is important spare and accessory parts in transmitter, and the quality of gas inlet rubber tube is by direct shadow
Ring the performance of invention motivation.Current vacuum gas inlet rubber tube typically uses isometrical sebific duct, refering to Fig. 2, and should
Kind sebific duct, when actually used, exist and inhales flat phenomenon, in turn result in the problem that engine charge is uneven,
Such as when supercharger speed fluctuates, and admission pressure reduces, sebific duct is inhaled flat, and air input of engine by air fluctuates,
Make engine performance stably be affected, even can make the flame-out car that goes out of diesel engine.
Summary of the invention
The present invention solves that technical problem present in known technology provides a kind of simple in construction, user
Just engine performance, is improved stable, it is to avoid cause flame-out car phenomenon of going out because gas inlet rubber tube air inlet is uneven
's.
The present invention solves that technical problem is adopted the technical scheme that present in known technology:
A kind of vacuum gas inlet rubber tube used for diesel engine, including sebific duct body, it is characterised in that: described glue
It is provided with at least provided with a deformable cavity, the internal diameter of described deformable cavity along sebific duct body length direction on tube body
More than the internal diameter of sebific duct body, the outer wall of described deformable cavity position sebific duct body forms projection, described projection
Two ends outer wall circular arc with sebific duct body respectively seamlessly transit, the inwall of described deformable cavity is circular arc knot
The inwall arc transition of structure, the inwall of deformable cavity and sebific duct body.
The present invention has the advantage that with good effect: owing to the present invention uses technique scheme, i.e. exist
The deformable cavity of one reducing is set on traditional isometrical sebific duct, the most effectively avoids when supercharger speed ripple
Dynamic, when admission pressure reduces, this sebific duct will not be inhaled flat；Air input of engine by air is avoided to fluctuate, it is ensured that to start
Machine stability, it is to avoid what introduction wave moved and caused makes the flame-out car problem of going out of diesel engine.It addition, it is true
Empty gas inlet rubber tube can bear bigger vibration, the deformation particularly axially stretched and traditional isometrical sebific duct
Compare more superior.
Accompanying drawing explanation
Fig. 1 is the structural representation of the present invention；
Fig. 2 is prior art construction schematic diagram.
In figure: 1, sebific duct body；101, deformable cavity.
Detailed description of the invention
For the summary of the invention of the present invention, feature and effect can be further appreciated that, hereby enumerate following example,
And it is as follows to coordinate accompanying drawing to describe in detail:
Referring to Fig. 1, a kind of vacuum gas inlet rubber tube used for diesel engine, including sebific duct body 1, described glue
It is provided with at least provided with a deformable cavity 101 along sebific duct body length direction on tube body, described deformable cavity
Internal diameter is more than the internal diameter of sebific duct body, and the outer wall of described deformable cavity position sebific duct body forms projection, described
Protruding two ends outer wall circular arc with sebific duct body respectively seamlessly transits, and the inwall of described deformable cavity is circular arc
The inwall arc transition of structure, the inwall of deformable cavity and sebific duct body.Use technique scheme, i.e. exist
The deformable cavity of one reducing is set on traditional isometrical sebific duct, the most effectively avoids when supercharger speed ripple
Dynamic, when admission pressure reduces, this sebific duct will not be inhaled flat；Air input of engine by air is avoided to fluctuate, it is ensured that to start
Machine stability, it is to avoid what introduction wave moved and caused makes the flame-out car problem of going out of diesel engine.It addition, it is true
Empty gas inlet rubber tube can bear bigger vibration, the deformation particularly axially stretched and traditional isometrical sebific duct
Compare more superior.
The above is only to presently preferred embodiments of the present invention, not the present invention is made any in form
Restriction, every technical spirit according to the present invention to any simple modification made for any of the above embodiments, etc.
With change and modification, belong in the range of technical solution of the present invention.
