Abstract
The utility model discloses an evaporated fuel oil gas storing and desorbing system for a motorcycle, which comprises a carbon tank connected with a fuel tank. The carbon tank is connected with a fuel oil evaporating and desorbing mouth on an air inlet system of an engine via a desorbing pipe and is integrated with a check valve. Both ends of the check valve are respectively communicated with the carbon tank and the desorbing pipe. The evaporated fuel oil gas storing and desorbing system utilizes the negative pressure in the fuel oil evaporating and desorbing pipe to open the check valve to effectively control the desorbing time of the evaporated fuel oil gas, and thus the evaporated fuel oil gas is not desorbed when the engine operates at a low speed, thereby avoiding adverse effects caused by the desorption of evaporated fuel oil gas to the engine operating at a low speed, particularly by the desorption of evaporated fuel oil gas to the discharge stability and the speed stability when the engine idles, and the startability and the like when the carbon tank is empty or full.
Description
Technical field
The utility model relates to the fuel evaporation oil gas storage desorption system that a kind of motorcycle is used.
Background technique
When motorcycle is worked, need to supply inflammable mixture to motor incessantly, at this moment need constantly to allow fuel gasification by fuel oil supply device, and allow fuel oil and a certain proportion of air of vaporization mix mutually to form inflammable mixture and send into motor, satisfy motor different demands to fuel oil under the different operating situation.
With reference to Fig. 1, Fig. 2, the fuel evaporation oil gas desorption system that present some motor car engine is used controls fuel evaporation oil gas desorption time with the PCV negative pressure control valve, its concrete structure is: comprise the canister 2 that is connected with fuel tank 1, described canister 2 is provided with PCV negative pressure control valve 3, the negative pressure pipe 4 of described PCV negative pressure control valve 3 is connected on the suction tude 51 of motor 5, the desorption pipe 6 of PCV negative pressure control valve 3 is connected with fuel evaporation desorption mouth 7 on the engine aspirating system, when vehicle driving, the negative pressure that suction tude 51 produces picks up the PCV diaphragm 31 in the PCV negative pressure control valve 3 by negative pressure pipe 4, make desorption mouth 7 conductings on charcoal jar 2 desorption mouths and the engine aspirating system, by desorption mouth 7 the fuel vapor mixed gas of charcoal jar 2 inside is adsorbed onto motor 5 internal combustions and burns.But the harmful effect that this structure is caused in the time of can't avoiding fuel evaporation oil gas to low engine speed, the harmful effect of the startability when the discharging stability during particularly to engine idle, speed stability and empty charcoal jar and full charcoal jar etc.And this project organization complexity, cost height, pipeline are many, car load difficult arrangement, rate of fault height, thereby are difficult to meet people's usage requirement.
Summary of the invention
In order to overcome the deficiencies in the prior art, the utility model provides a kind of fuel evaporation oil gas reasonable in design, simple in structure, with low cost, that pipeline is few, car load is arranged easily, rate of fault motorcycle engine low, energy-conserving and environment-protective is used to store the desorption system.
The technological scheme that its technical problem that solves the utility model adopts is:
The fuel evaporation oil gas that a kind of motorcycle is used stores the desorption system, comprise the canister that is connected with fuel tank, canister is connected with fuel evaporation desorption mouth on the engine aspirating system by desorption pipe, be integrated with one-way valve on the described canister, the two ends of one-way valve communicate with canister and desorption pipe respectively;
As further improvement in the technical proposal, described engine aspirating system can be suction tude on fuel oil supply device, the motor or empty filter.
The beneficial effects of the utility model are: the negative pressure in this product utilization fuel evaporation desorption pipe comes open check valve to reach the time of effective control fuel evaporation oil gas desorption, do not carry out fuel evaporation oil gas desorption when making low engine speed, the harmful effect that is caused in the time of can avoiding fuel evaporation oil gas desorption to low engine speed like this, the startability when the discharging stability when particularly the desorption of fuel evaporation oil gas is to engine idle, speed stability and empty charcoal jar and full charcoal jar etc. causes harmful effect.The technical program is simple in structure, with low cost, and pipeline is few, car load is arranged easily, rate of fault is low, thereby realizes collecting exhaust of oil in effective desorption charcoal jar, does not influence engine performance again, and the purpose that reaches environmental protection satisfies the fuel evaporation Abgasgesetz.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is the fuel evaporation oil gas desorption structural drawing that existing motorcycle is used;
Fig. 2 is the structural drawing that existing desorption system is in detachment status;
Fig. 3 is a structural representation of the present utility model;
Fig. 4 is the structural representation that is in detachment status of the present utility model.
Embodiment
With reference to Fig. 3, Fig. 4, the fuel evaporation oil gas that a kind of motorcycle is used stores the desorption system, comprise the canister 2 that is connected with fuel tank 1, canister 2 is connected with fuel evaporation desorption mouth 7 on the engine aspirating system by desorption pipe 6, be integrated with one-way valve 8 on the described canister 2, the two ends of one-way valve 8 communicate with canister 2 and desorption pipe 6 respectively.
Described engine aspirating system can be suction tude 51 on fuel oil supply device 10, the motor 5 or empty filter 9.
During vehicle driving, desorption mouth 7 negative pressure on the engine aspirating system pick up the diaphragm 81 in the one-way valve 8, make desorption mouth 7 conductings on charcoal jar 2 desorption mouths and the engine aspirating system, by desorption mouth 7 the fuel vapor mixed gas of charcoal jar 2 inside being adsorbed onto motor 5 internal combustions burns, negative pressure in this product utilization fuel evaporation desorption pipe 6 is come open check valve 8, reach the time of effective control fuel evaporation oil gas desorption, do not carry out fuel evaporation oil gas desorption when making low engine speed, the harmful effect that is caused in the time of can avoiding fuel evaporation oil gas desorption to low engine speed like this, the discharging stability when particularly the desorption of fuel evaporation oil gas is to engine idle, startability when speed stability and empty charcoal jar and full charcoal jar etc. causes harmful effect.The technical program is simple in structure, with low cost, and pipeline is few, car load is arranged easily, rate of fault is low, thereby realizes collecting exhaust of oil in effective desorption charcoal jar 3, does not influence engine performance again, and the purpose that reaches environmental protection satisfies the fuel evaporation Abgasgesetz.
