Description
Technical field
The invention belongs to technical field of motorcycles, specifically, the particularly absorption plant of motorcycle with electronic fuel injection system oil steam in oil tank.
Background technique
Traditional two-wheeled or motor tricycle all adopt Carburetor mode fuel feeding.Fuel tank is the parts of motorcycle splendid attire fuel oil, is connected to fuel tap in the bottom of fuel tank by oil pipe, and fuel tap connects Carburetor by oil pipe again.Carburetor is according to the needs of motor under different operating modes, with fuel evaporation, and is mixed into inflammable mixture by a certain percentage with air, in time enters cylinder in right amount.Top at fuel tank offers oil filler, in this oil filler tank cap lock is installed.Tank cap lock plays sealing, opens the tank cap lock gasoline of can annotating in fuel tank.The bottom of tank cap lock generally offers vent, and this vent communicates with the external world in needs, with the pressure balance inside and outside the assurance fuel tank.
As everyone knows, the boiling point of gasoline is lower, and gasification easily can form oil vapor in the top in motorcycle tank.Oil vapor outwards overflows when opening tank cap lock, can cause the fuel oil waste on the one hand, pollutes the environment on the other hand, does not meet environmental requirement.At present, public oil steam in oil tank absorption pattern is that copper pipe is installed in fuel tank, the upper end-hole of this copper pipe is near the inner roof wall of fuel tank, the lower end mouth of copper pipe is drawn from the bottom surface of fuel tank, and is connected with canister by pipeline, and the adsorption force by canister is with the oil vapor sucking-off in the fuel tank.Owing to have the spacing of 5-15mm between the upper end-hole of copper pipe and the fuel tank inner roof wall, in the process of motorcycle driving, along with road jolts, gasoline phugoid oscillation in the fuel tank, can not have the upper end-hole of copper pipe, enter canister then without obstruction, causing canister to damage can't use.
Energy-conservation and needs environmental protection are just impelling electric jet technology progressively to replace Carburetor.Electric jet technology has fundamentally improved the task performance of cylinder, make motor be in a kind of running state of the best constantly, thereby having increased substantially the performance of motor, reduced exhaust emission simultaneously, is one of effective measures of the energy-conservation and emission pollution problem of current comprehensive solution.In addition, motorcycle with electronic fuel injection system can reduce oil consumption greatly, for the Consumer brings material benefit, so from Consumer's angle, motorcycle with electronic fuel injection system popularizing on market also is an irreversible trend.For these reasons, each motorcycle manufacturer of China has all released the EFI product successively, the fuel tank of motorcycle with electronic fuel injection system adopts oil pump fuel-displaced, but the absorption pattern of oil steam in oil tank is still indiscriminately imitated the technology of Carburetor motorcycle, exist assimilation effect undesirable, deficiency such as the easy oil-feed of canister damages, working life is long.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of fuel oil that can effectively prevent to enter the absorption plant that is used for oil steam in oil tank of canister.。
Technological scheme of the present invention is as follows: a kind of absorption plant that is used for oil steam in oil tank, comprise fuel tank, canister, tank cap lock, fuel tap, first tracheae and gas pipeline, top at fuel tank is provided with oil filler, in this oil filler tank cap lock is installed, and the bottom of tank cap lock has vent.Bottom at described tank cap lock also has inlet hole, is connected to gas pipeline on this inlet hole, and this gas pipeline is drawn from the bottom of fuel tank, and is connected with the import of fuel tap, and the outlet of described fuel tap is connected with canister by first tracheae.
Adopt above technological scheme, canister produces adsorption force by EFI ECU control, and the vent of the oil vapor in the fuel tank by the tank cap lock bottom sucked in the tank cap lock, and oil vapor enters breather line by inlet hole again, enter fuel tap by breather line then, after first tracheae enters canister.The present invention utilizes the ventilate characteristics of not oil-feed of tank cap lock dexterously, make the pipeline and the fuel oil in the fuel tank that absorb oil vapor isolated fully, prevented that effectively fuel oil from entering canister by pipeline, guaranteed the usability of canister, improve the effect that absorbs oil vapor, prolonged the working life of canister.The present invention also is applied to the fuel tap on the Carburetor motorcycle on the motorcycle with electronic fuel injection system dexterously, fuel tap plays valve, with conducting as required or close the suction line of oil vapor, motorcycle enterprises need not be driven grinding tool in addition and make special valve, utilize existing resource thus as much as possible, reduced cost of production.
Have two inlet holes in the bottom of described tank cap lock, these two inlet holes are symmetrically distributed in the both sides of vent, and are connected with fuel tap by gas pipeline.Above structure can evenly absorb the oil vapor that enters tank cap lock, has further improved the effect that absorbs.
For simplified structure, the convenient installation, and it is mobile smooth and easy to help oil vapor, described gas pipeline is made up of second tracheae, the 3rd tracheae, three-way pipe and the 4th tracheae, the inlet end of described second, third tracheae is connected with two inlet holes of tank cap lock bottom respectively, the outlet side of second, third tracheae is connected on two interfaces of three-way pipe, the 3rd interface of described three-way pipe is connected with an end of the 4th tracheae, and the other end of the 4th tracheae is connected with the import of fuel tap.
Connect, simplify mounting process for the ease of tracheae, the hole wall of described inlet hole extends downwards, forms joint, and this joint is inserted in by the tracheae of correspondence.
Beneficial effect: the present invention utilizes the combination of tank cap lock, fuel tap and pipeline, oil vapor in the fuel tank can be absorbed into canister, and avoided fuel oil to enter in the canister, guaranteed the usability of canister, prolonged the working life of canister, have characteristics such as novel, simple in structure, good reliability, highly versatile, be adapted to various types of motorcycle with electronic fuel injection system.
