Abstract
The utility model relates to a kind of suspension type fuel oil injector rails, including distribution pipe (1), fuel injector mounting base (2) and suspension type fuel injector (3), the fuel oil injector rail further includes drop-pipe mounting base (4) and drop-pipe (5), described drop-pipe (5) one end passes through fuel injector mounting base (2) connection suspension type fuel injector (3) by drop-pipe mounting base (4) connection distribution pipe (1), the other end.Compared with prior art, the utility model has many advantages, such as generally to be applicable in, mitigates weight gain, saves cost.
Description
Technical field
The utility model relates to fuel oil injector rail fields, more particularly, to a kind of suspension type fuel oil injector rail.
Background technique
As shown in Figure 1, in-cylinder direct-jet oil rail is connected to fuel injector and high-pressure oil passage, fuel injector is fixed on the engine.
While oily rail bearing is by certain oil pressure, it need to guarantee to distribute enough high pressure fuels to each fuel injector.Due to engine boundary
Space is smaller, and fuel injector has specific setting angle requirement, to exempt to interfere, it is desirable that oily rail structure meets different start as far as possible
Machine layout requirements.Suspension type fuel injector is fixed with the fuel injector mounting base interface structure on oily rail, is outer diameterCylinder
Type structure, it has not been convenient to extend, suspension type fuel injector is caused to be only used for side engine.
Demand with market mid-ships engine to suspension type fuel oil injector rail, existing suspension type fuel oil injector rail are necessary
Extension oil circuit is carried out, is had the following problems if extending fuel injector mounting base:
1, it is cooperation mid-ships engine demand, extends fuel injector mounting base and easily interfere with motivation cylinder cap, be unable to satisfy and start
Machine layout requirements；
It 2, is cooperation mid-ships engine demand, extending fuel injector mounting base causes oily rail weight to increase, and is unable to satisfy light weight
Change and requires；
3, it is cooperation mid-ships engine demand, extends fuel injector mounting base, material increases, and process for machining increases, and causes
Oily rail increased costs.
All engines can not be applied to by extending fuel injector mounting base, and cost increase, weight increase.
Utility model content
The purpose of this utility model is exactly to provide a kind of suspension type spray to overcome the problems of the above-mentioned prior art
Oily device oil rail.
The purpose of this utility model can be achieved through the following technical solutions:
A kind of suspension type fuel oil injector rail, including distribution pipe, fuel injector mounting base and suspension type fuel injector, the fuel oil injector
Rail further includes drop-pipe mounting base and drop-pipe, and described drop-pipe one end connects distribution pipe by drop-pipe mounting base, another
End connects suspension type fuel injector by fuel injector mounting base.
Preferably, the drop-pipe mounting base is connect with drop-pipe by welding manner.
Preferably, the drop-pipe is connect with fuel injector mounting base by welding manner.
Preferably, the drop-pipe mounting base is connect with distribution pipe by welding manner.
Preferably, the fuel injector mounting base and suspension type fuel injector are by being connected together.
Preferably, the drop-pipe is the drop-pipe being made by bending technique.
Compared with prior art, the utility model has the advantage that
1, the application range of suspension type fuel oil injector rail has been widened, side engine and mid-ships engine are applicable；
2, space is saved in drop-pipe design, small to requirements of installation space, effectively reduces the requirement to distribution engine；
3, it while meeting oil circuit extension, has reduced the increment of oily rail weight to the greatest extent, has met vehicle lightweight requirements；
4, down tube structure simple process, materials are saved, and cost is effectively controlled.
Detailed description of the invention
Fig. 1 is former suspension type fuel oil injector rail structural schematic diagram；
Fig. 2 is the suspension type fuel oil injector rail structural schematic diagram of the utility model.
Wherein 1 is distribution pipe, and 2 be fuel injector mounting base, and 3 be suspension type fuel injector, and 4 be drop-pipe mounting base, and 5 be lower outstanding
Pipe.
Specific embodiment
Below by the technical scheme in the utility model embodiment is clearly and completely described, it is clear that described
Embodiment is a part of the embodiment of the utility model, rather than whole embodiments.Based on the embodiments of the present invention, originally
Field those of ordinary skill every other embodiment obtained without making creative work all should belong to this
The range of utility model protection.
As shown in Fig. 2, a kind of suspension type fuel oil injector rail, including distribution pipe 1, fuel injector mounting base 2 and suspension type oil spout
Device 3, the fuel oil injector rail further include drop-pipe mounting base 4 and drop-pipe 5, and described 5 one end of drop-pipe is installed by drop-pipe
Seat 4 connects distribution pipe 1, and the other end connects suspension type fuel injector 3 by fuel injector mounting base 2.
The drop-pipe mounting base 4 is connect with drop-pipe 5 by welding manner.The drop-pipe 5 and fuel injector is pacified
Seat 2 is filled to connect by welding manner.The drop-pipe mounting base 4 is connect with distribution pipe 1 by welding manner.The oil spout
Device mounting base 2 and suspension type fuel injector 3 are by being connected together.Guarantee structural strength and leakproofness.
The drop-pipe 5 is the drop-pipe being made by bending technique, is not necessarily to process for machining.The distribution
High pressure fuel in pipe 1 enters fuel injector mounting base 2 by drop-pipe 5, has both guaranteed conveying high-pressure fuel oil to suspension type fuel injector
3, and avoid interfering with engine cylinder head.
Above description is only a specific implementation of the present invention, but the protection scope of the utility model is not limited to
In this, anyone skilled in the art within the technical scope disclosed by the utility model, can be readily occurred in various
Equivalent modifications or substitutions, these modifications or substitutions should be covered within the scope of the utility model.Therefore, this is practical
Novel protection scope should be subject to the protection scope in claims.
