Technical Field
The invention belongs to the technical field of carbon tanks, and particularly relates to a national six carbon tank with adjustable desorption flow.
Background
The establishment and implementation of the national VI standard of the light passenger vehicle can greatly reduce the pollutant emission of the vehicle, thereby needing to comprehensively improve the emission control capability of the vehicle. At present, the main countermeasure of the whole vehicle development for meeting the national six-evaporation and refueling emission requirements is to increase the volume of a carbon tank and increase the filling amount of activated carbon to ensure that volatile oil gas can be fully captured. Therefore, a large amount of fuel vapor is absorbed by the carbon canister, desorbed by the engine, enters the engine, is mixed with the mixed gas and then is combusted.
However, since the capacity of the six carbon canister is several times of that of the five carbon canister, the adsorption capacity is greatly enhanced, and a large amount of oil gas is generated during desorption. Therefore, if the vehicle takes place when the normally open trouble of canister solenoid valve under last electric state, because canister adsorbs mouthful and the desorption mouth is close apart from, middle baffle length too short will lead to the unable and air intensive mixing of oil gas directly to get into air intake manifold, in addition the stagnation of canister solenoid valve is normally opened, and the oil gas of canister is washed and is not controlled by the EMS to lead to the rich, take place the vehicle because rich start fails, consequently, we provide a six carbon canisters in state that desorption flow can be adjusted.
Disclosure of Invention
The invention aims to provide a national six-carbon canister with adjustable desorption flow, which can change the desorption flow of the canister by adding a flow regulating valve on the canister and controlling the canister by an ECU (electronic control unit), solve the problem that the vehicle starts to fail due to too large desorption amount when the normal opening fault of a canister electromagnetic valve occurs in the powered state of the vehicle, and solve the problem provided by the background technology.
In order to achieve the purpose, the invention provides the following technical scheme:
a six carbon pots of state with adjustable desorption flow, including the carbon pot body, carbon pot lead to the atmosphere pipe, carbon pot adsorption tube, carbon pot desorption tube and flow control valve, the said carbon pot body communicates with carbon pot lead to atmosphere pipe, carbon pot adsorption tube and carbon pot desorption tube separately, the said flow control valve is installed on carbon pot desorption tube;
flow control valve includes casing and valve body, install the power signal connector in the casing, the one end of casing and the one end fixed connection of valve body, the lumen of casing is linked together with the lumen of valve body, slidable mounting has armature in the lumen of casing, the fixed push rod that has cup jointed of one end of armature, the fixed grafting of one end of push rod has the plunger, the lower extreme welded fastening of plunger has reset spring, reset spring's one end is protruding inconsistent with the inner wall of valve body.
Preferably, a gasket is fixedly bonded to the bottom of the plunger.
Preferably, the side groove of the shell and the side groove of the valve body are fixedly sleeved with sealing rings.
Preferably, the carbon canister adsorption pipe is communicated with an oil tank through a fuel oil pipe.
Preferably, the carbon canister desorption pipe is communicated with an engine through a fuel pipe.
Preferably, the valve body and the carbon canister body are of an integral structure through injection molding.
Compared with the prior art, the invention has the beneficial effects that:
through flow control valve 5's use, can adjust the mouth of pipe of charcoal jar desorption pipe and open the size, can adjust charcoal desorption volume, and flow control valve 5 normal conditions is normally open state down, when the vehicle starts at every turn, ECU passes through 8 control flow control valves of power signal connector 5 switches on, 3 the push rod promotes 4 plungers and makes the valve close, make charcoal jar desorption pipe 4 be in the closed condition, gas is unable to pass through, the unable desorption of fuel steam, like this, even solenoid valve normally open fault in charcoal jar main part 1 does not have oil gas yet and gets into the engine and leads to the gas mixture too thick, cause the vehicle start failure. After the carbon canister desorption device is started successfully, the ECU controls the flow regulating valve 5 to be opened through the power supply signal connector 8, so that the carbon canister desorption pipe 4 can be connected, and the carbon canister desorption can work normally.
