Abstract
The utility model discloses a kind of fuel tank with liquid-collecting box, including fuel tank weight valve, fuel tank evaporation tube, liquid-collecting box and canister connecting tube, the fuel tank weight valve is set to top of oil-tank；The liquid-collecting box is connected on fuel tank；It is equipped with a partition among the liquid-collecting box, liquid-collecting box is divided into upper layer and lower layer, lower layer is equipped with a fuel-steam import, and upper layer is equipped with a fuel-steam outlet；A fuel-steam via hole is offered on the partition；The fuel tank evaporation tube connects the fuel tank weight valve and fuel-steam import；The canister connecting tube connection canister and fuel-steam outlet.The utility model can effectively prevent the liquid fuel in fuel tank to enter in canister, the problem for causing canister failure to cause emission exceeded.
Description
Technical field
The utility model relates to automobile oil tank system technical field, specifically a kind of fuel tank with liquid-collecting box.
Background technique
Further stringent with emission regulation, a kind of online oiling Investigation of Petroleum Vapor Recovery Technology of gasoline car occurs gradually over market
In, the principle of this technology is during gasoline car refuels, and fuel tank internal oil vapour is not discharged into atmosphere, but is passed through
After canister filtering absorption, more clean gas, the oil gas recoverable of absorption are discharged by canister.Currently, general vehicle is all
The design of fuel tank loss of weight valve and canister is directly connected to using evaporation tube, which is easy to cause in fuel tank full oil or is jolting
Under road conditions, liquid fuel directly passes through evaporation tube and enters in canister, causes the failure of canister.
Utility model content
The utility model provides a kind of fuel tank with liquid-collecting box, including fuel tank weight valve, oil in order to solve the above problem
Case evaporation tube, liquid-collecting box, canister connecting tube and fuel-steam circulation pipe, the fuel tank weight valve are set to top of oil-tank；The collection
Liquid box is connected on fuel tank；It is equipped with a partition among the liquid-collecting box, liquid-collecting box is divided into upper layer and lower layer, lower layer is equipped with one
Fuel-steam import, upper layer are equipped with a fuel-steam outlet；A fuel-steam via hole is offered on the partition；The oil
Case evaporation tube connects the fuel tank weight valve and fuel-steam import；The canister connecting tube connection canister and the fuel-steam
Outlet.
Compared with prior art, the utility model can effectively solve liquid using the design of liquid-collecting box and liquid-collecting box partition
Fuel oil directly passes through the problem of evaporation tube enters canister, canister is caused to fail.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model；
Fig. 2 is the structural schematic diagram of liquid-collecting box；
Fig. 3 is the schematic internal view that liquid-collecting box removes lid；
Fig. 4 is the cross-sectional view of liquid-collecting box.
Description of symbols: 1, fuel tank weight valve, 2, fuel tank evaporation tube, 3, liquid-collecting box, 301, partition, 302, fuel-steam
Import, 303, fuel-steam outlet, 304, fuel-steam via hole, 4, canister connecting tube.
Specific embodiment
The embodiments described below with reference to the accompanying drawings are exemplary, is only used for explaining the utility model, and cannot solve
It is interpreted as limitations of the present invention:
A kind of fuel tank with liquid-collecting box as shown in Figs 1-4, including fuel tank weight valve 1, fuel tank evaporation tube 2, liquid-collecting box
3, canister connecting tube 4 and fuel-steam circulation pipe 5, the fuel tank weight valve 1 are set to top of oil-tank；The liquid-collecting box 3 is connected in
On fuel tank；It is equipped with partition 301 among the liquid-collecting box 3 to divide liquid-collecting box 3 for upper layer and lower layer, lower layer is equipped with a fuel oil and steams
Vapor inlet 302, upper layer are equipped with a fuel-steam outlet 303；A fuel-steam via hole 304 is offered on the partition 301；
The fuel tank evaporation tube 2 connects the fuel tank weight valve 1 and fuel-steam import 302；The canister connecting tube 4 connect canister and
The fuel-steam outlet 303.
The utility model is achieved like this, when fuel tank is in completely, oil or running car are in the road conditions jolted, portion
Divide liquid fuel to enter in fuel tank evaporation tube 2 by fuel tank weight valve 1, then enter in liquid-collecting box 3 through evaporation tube 2, due to evaporation
Pipe 2 connects lower layer's fuel-steam import 302 of liquid-collecting box 3, and liquid-collecting box 3 is equipped with partition 301, therefore can play to liquid fuel
Barrier action prevents it from entering in canister；The design of fuel-steam via hole 304 on partition 301, and can be the fuel-steam of volatilization
Access is provided, the absorption to fuel-steam is completed by canister, the oil gas recoverable of absorption improves fuel efficiency.
The structure, features, and effects of the present invention is described in detail based on the embodiments shown in the drawings, with
Upper described is only the preferred embodiment of the utility model, but the present invention does not limit the scope of implementation as shown in the drawings, it is all according to
Change or equivalent example modified to equivalent change made by conception according to the utility model, still without departing from specification and figure
When showing covered spirit, it should be within the protection scope of the present utility model.
