Background technique
The motorcycle fuel evaporation system is the indispensable parts of its motor, generally comprises canister, vapourizer tube and necessary associate member.Mainly be to be used for preventing that gasoline volatilization in the fuel tank to atmosphere or cause danger, simultaneously, can guarantee fuel tank internal air pressure balance, prevent that engine oil is not enough and stop working.During use, behind engine misses, gasoline vapor and fresh air are in in-tank mixing and be stored in the activated carbon canister, behind engine start, the electromagnetic valve that is contained between activated carbon canister and the intake manifold is opened, gasoline vapor in the activated carbon canister is brought into by clean air under the degree of vacuum effect of suction tude and is participated in burning in the cylinder, also can enter the fuel tank balance that keep-ups pressure simultaneously; Not only reduce discharging, and reduced oil consumption.
In the prior art, the fuel evaporation tube opening is positioned at fuel tank by last, and is provided with deaerator, and deaerator is connected to " toppling valve " in the fuel tank disposed outside by vapourizer tube, be connected to the adsorbent charcoal jar then, thereby reach the purpose of absorption and desorption fuel-steam.There are not tangible splashproof and seepage control measure between oil and water seperator and the vapourizer tube, thereby, vapourizer tube travels or car load is splashed into fuel oil because of the car load vibration when toppling over or infiltrates in the fuel evaporation pipeline at car load, might cause pipeline blockage, influencing canister uses, and influence fuel tank internal air pressure, cause Finished Motorcycle of motorcycle to occur coming oil slowly or do not come oily phenomenon at last, thereby influence the proper functioning of motor.
Therefore, need transform the motorcycle fuel evaporation system, can avoid fuel oil to be splashed into or infiltrate in the fuel evaporation pipeline, prevent the fuel evaporation pipe choking, thereby can guarantee the tank pressure balance, be beneficial to and reduce discharging and oil consumption, prolong the working life of canister and the power performance and the usability of assurance car load.
Summary of the invention
In view of this, the invention provides a kind of motorcycle fuel evaporation structural assembly and motorcycle thereof, can avoid fuel oil to be splashed into or infiltrate in the fuel evaporation pipeline, prevent the fuel evaporation pipe choking, thereby can guarantee the tank pressure balance, be beneficial to and reduce discharging and oil consumption, prolong the working life of canister and the power performance and the usability of assurance car load.
Motorcycle fuel evaporation structural assembly of the present invention, comprise vapourizer tube and fuel tank lock body, the lock body core Spielpassung of described fuel tank lock body is with T shape setting sleeve outward, vapourizer tube is fixedly set in fuel tank junner bush outer round surface, the edge of a wing of T shape setting sleeve is provided with axial pass-through holes, described vapourizer tube embed axial pass-through holes and be communicated in the T shape setting sleeve edge of a wing and fuel tank lock body sealed department between the space, the gap between space between the described T shape setting sleeve edge of a wing and the fuel tank lock body sealed department and lock body core and the T shape setting sleeve formed the gas passage jointly.
Further, described axial pass-through holes forms counter bore structure from the bottom to top, is provided with seal ring at the bottom of the counter bore structure, vapourizer tube upper end portion compression seal circle; Adopt counter bore structure, must not seal ring be set supporting effect at the bottom of can utilizing counterbore, utilize the elastic compression vapourizer tube upper end portion of seal ring itself, formation better seal effect prevents that liquid fuel from entering vapourizer tube.
Further, described T shape setting sleeve forms the flange that is connected as a single entity with its edge of a wing, and described axial pass-through holes is through flange; This structure is beneficial to the grafting intensity that strengthens vapourizer tube and axial pass-through holes, thereby guarantees that vapourizer tube does not take place laterally to move after grafting, guarantees its sealing effect.
Further, described vapourizer tube is fixed in fuel tank junner bush outer round surface from the bottom to top and passes the seal washer of fuel tank lock body; Compact overall structure is not destroyed the sealability of seal washer.
Further, described fuel tank junner bush outer round surface is provided for the fixedly fixed card of vapourizer tube; Simple in structure, easy disassembling.
The invention also discloses a kind of motorcycle of using the motorcycle fuel evaporation structural assembly.
Beneficial effect of the present invention: motorcycle fuel evaporation structural assembly of the present invention and motorcycle thereof, the mistake gas channel connection that forms between the position of fuel evaporation tube opening beyond the engine oil tank and fuel tank lock body and the T shape setting sleeve, vapourizer tube by fuel tank internal by and fixedly be connected in the fuel tank junner bush, it is firm that vapourizer tube is connected, and do not destroy the integrity of fuel tank and fuel tank lock body; Fuel-steam keeps clear by crossing the turnover of gas passage, and liquid is positioned at the fuel tank outside by choked flow owing to cross the existence and the fuel evaporation tube opening of gas passage, can avoid fuel oil to be splashed into or infiltrate in the fuel evaporation pipeline, prevent the fuel evaporation pipe choking, thereby can guarantee the tank pressure balance, be beneficial to and reduce discharging and oil consumption, prolong the working life of canister and the power performance and the usability of assurance car load; The present invention has cancelled parts such as deaerator and toppling valve, has simplified the manufacturing process of fuel tank, has reduced cost, and the structural configuration of car load is more prone to.
