Abstract
The utility model discloses a car adds oil pipe, include and add oil pipe, add the inner wall of the oil tubing upper portion and be provided with mound pressure spacing groove, being provided with the shell with oil pipe with the welding of oil pipe top, be provided with upper and lower installation fixed bolster respectively on adding oil pipe middle part and lower part outer wall add oil pipe shell top and be provided with the mouth with oil pipe, be equipped with mounting flange with the oil pipe external surface of the housing cover, set up the gas outlet with oil pipe shell lateral wall, the gas outlet intercommunication is provided with the breather pipe, the breather pipe and add the oil pipe bottom respectively the intercommunication be provided with first, the 2nd coupling hose. The utility model discloses the advantage lies in effectively improving that fuel steam pressure distributes and flows in the fuel tank, and greatly reduced refuels the diffusion of in -process fuel steam in to the atmosphere, and it is extravagant effectively to reduce the energy, reduces simultaneously to refuel the environmental pollution that the in -process led to the fact.
Description
Technical field
The utility model relates to automotive field, especially relates to a kind of automobile refuelling pipe.
Background technology
In general, the gasoline discharge vaporization of car load is divided into: running discharge vaporization, hot dipping discharge vaporization, discharge vaporization, parking discharge vaporization, five parts such as discharge vaporization of refueling between daytime.For oiling evaporation, there is following problem in current domestic vehicles: oil filling port does not seal, in refueling process, VOC can from the minimum path of resistance by fuel filler pipe to airborne release, because the internal diameter of fuel filler pipe and breather pipe is more much bigger than the internal diameter of discharge vaporization mouth, therefore only have small part VOC to enter charcoal tank in refueling process, and major part is all direct overflows from oil filling port; The position that the electrolyte level that fuel tank is annotated must be over oiling muzzle could form fluid-tight and stop refueling.Therefore do not install the fuel tank of oiling device for recovering oil and gas additional, what gasoline may be made to add is fuller, and serious made gasoline enters canister, and canister was lost efficacy; When gasoline sprays into fuel filler pipe from nozzle nozzle, form jet at oil filling port place, cross to produce with the gasoline vapor flowed out in fuel tank and splash and accelerate atomization and vaporization.
Summary of the invention
The utility model object is that providing a kind of avoids great amount of fuel oil steam in refueling process to be diffused into the automobile refuelling pipe air from oil filling port.
For achieving the above object, the utility model can take following technical proposals:
Automobile refuelling pipe described in the utility model, comprises fuel filler pipe; Described fuel filler pipe upper inside wall is provided with pier pressure position-limited trough, fuel filler pipe welded top is provided with fuel filler pipe shell, upper and lower mounting and fixing bracket is respectively arranged with in the middle part of fuel filler pipe He on the outer wall of bottom, described fuel filler pipe cover top portion is provided with filler neck, is set with attachment flange at fuel filler pipe outer shell outer wall; Offer air extractor duct at fuel filler pipe side wall of outer shell, described air extractor duct connection is provided with breather pipe, and described breather pipe is provided with first, second connecting hose with being communicated with respectively bottom fuel filler pipe.
The utility model advantage is effectively to improve fuel-steam distribution of pressure and flowing in fuel tank, greatly reduces refueling process IFO intermediate fuel oil steam to the diffusion in air, effectively reduces energy dissipation, reduce the environmental pollution caused in refueling process simultaneously.It is excessively dark that pier pressure position-limited trough can avoid nozzle to insert fuel filler pipe, causes nozzle and filler neck gouging abrasion; Breather pipe and fuel filler pipe, in conjunction with fuel tank, make refueling process IFO intermediate fuel oil case steam inside be formed in fuel tank inside and circulate, avoid fuel-steam to leak.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
As shown in Figure 1, automobile refuelling pipe described in the utility model, comprises fuel filler pipe 1; Described fuel filler pipe 1 upper inside wall is provided with pier pressure position-limited trough 2, fuel filler pipe 1 welded top is provided with fuel filler pipe shell 3, upper and lower mounting and fixing bracket 4,5 is respectively arranged with in the middle part of fuel filler pipe 1 He on the outer wall of bottom, described fuel filler pipe shell 3 top is provided with filler neck 6, is set with attachment flange 7 at fuel filler pipe shell 3 outer wall; Offer air extractor duct at fuel filler pipe shell 3 sidewall, described air extractor duct connection is provided with breather pipe 8, and described breather pipe 8 is provided with first, second connecting hose 9,10 with being communicated with respectively bottom fuel filler pipe 1.
