Abstract
The utility model discloses a direct-injecting fuel distribution pipe device in a cylinder, comprising a main pipeline and an oil injector assembled in an oil injector seat; fuel entering a distribution pipe is supplied to each oil injector by the main oil pipe; the oil injector seat and the main oil pipe are detachable and are connected together by a slender pipe. The direct-injecting fuel distribution pipe device reduces the requirements on strength and rigidity of the main oil pipe and the installation strength thereof. Simultaneously, the main oil pipe can be flexibly arranged in other places with larger space, thus being conducive to the compact arrangement of other parts.
Description
Technical field
The utility model relates to a kind of fuel distribution pipe arrangement, relates in particular to a kind of in-cylinder direct injection fuel distribution pipe arrangement.
Background technique
Oil injector seat directly is connected with main oil pipe in the existing high pressure gasoline distribution piping, major part all is delivered on the main oil pipe power that produces during oil sprayer work with being out of shape very, thereby not only improved the requirement to rigidity of main oil pipe own and intensity, also the mounting type to distribution piping proposes higher requirement.In addition, since oil injector seat, main oil pipe, pipe joint, backbone block all needs to be installed near the engine cylinder cover, assembling and withdrawal space demand height, design flexibility is relatively poor, also is unfavorable near the compact Layout of the part of engine cylinder cover.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of in-cylinder direct injection fuel distribution pipe arrangement, not only can reduce requirement to rigidity of main oil pipe own and intensity, also reduced being responsible for the requirement of installation strength, simultaneously near the mounting or dismounting space requirement the engine cylinder cover is reduced, can flexible arrangement.
For solving the problems of the technologies described above, the technological scheme of the utility model in-cylinder direct injection fuel distribution pipe arrangement is, comprise main oil pipe, be assemblied in the oil sprayer in the oil injector seat, the fuel oil that enters in the distribution piping is supplied with each oil sprayer by main oil pipe, oil injector seat and main oil pipe are detachable, and link together by slender pipe.
Be that by the conical surface or welded seal, being threaded by the conical surface between slender pipe and oil injector seat seals between slender pipe and main oil pipe as further improvement of the utility model.
Main oil pipe of the present utility model and oil injector seat are all fixed separately, because the reaction force that produces during oil sprayer work mainly acts on oil injector seat, the power that is delivered to main oil pipe by slender pipe is very little, therefore reduced to the strength and stiffness of main oil pipe itself with and the requirement of installation strength.But the main oil pipe flexible arrangement more helps the compact Layout of other parts in bigger place, other space simultaneously.
Description of drawings
Below in conjunction with drawings and Examples the utility model is described in further detail:
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is an example structure schematic representation of the present utility model.
Reference character is 1 for oil injector seat among the figure, and 2 be slender pipe, and 3 is main oil pipe, and 4 is pipe joint, and 5 is the main oil pipe supporting plate, and 6 is sensor connector, and 7 is engine cylinder cover, and 8 is that oil sprayer 9 is the in-cylinder direct injection fuel dispensing tube, and 10 is spark coil.
Embodiment
As shown in Figure 1, oil sprayer is assemblied in the oil injector seat 1, and two bolts hole are arranged in each oil injector seat 1, can fix oil injector seat.Main oil pipe 3 is fixed by supporting plate 5.Slender pipe 2 connects oil injector seat 1 and main oil pipe 3.During actual fuel feeding, fuel oil enters main oil pipe 3 by pipe joint 4 earlier, main oil pipe 3 is distributed to each oil sprayer to fuel oil by slender pipe 2 then, is contained in the fuel pressure in the rail pressure sensor test main oil pipe 3 on the sensor holder 6 in whole work engineering, and feeds back to control system and regulate.
As shown in Figure 2, oil injector seat in the in-cylinder direct injection fuel dispensing tube 9 is installed in the groove of engine cylinder cover 7, owing near the oil sprayer 8 spark coil 10 is arranged, arrangement space is limited, main oil pipe 3 is arranged in the opposite side away from oil sprayer 8, and 3 of oil injector seat 1 and main oil pipes link together by slender pipe 2.
In the utility model, be connected by slender pipe 2 between main oil pipe 3 in the fuel dispensing tube of petrol engine and oil injector seat, wherein slender pipe 2 was realized with being connected by conical surface seal or welding of 3 of main oil pipes, slender pipe was realized by conical surface seal with being connected generally of 1 of oil injector seat, was convenient to dismounting.During fuel dispensing tube 9 work, fuel oil is introduced into main oil pipe 3, passes through slender pipe 2 then each oil sprayer 8 of fuel delivery.In this structure, main oil pipe 3 is all fixed separately with oil injector seat 1, because the reaction force that produces during oil sprayer work mainly acts on oil injector seat 1, the power that is delivered to main oil pipe 3 by slender pipe 2 is very little, therefore not only reduced requirement, also reduced the requirement of its installation strength the strength and stiffness of main oil pipe itself., so help near the compact Layout of the part of engine cylinder cover in addition because but main oil pipe 3 flexible arrangement in bigger place, other space, in oil sprayer 8 one sides, only need be considered the mounting or dismounting space of oil sprayer 8 and oil injector seat 1 near the engine cylinder cover place.
