Description
[technical field]
The utility model relates to the fuel fume control field of hybrid electric vehicle engine; More particularly, the utility model relates to a kind of hybrid vehicle that is used for the fuel fume control system of hybrid electric vehicle engine and comprises it.
[background technique]
Existing topmost automotive fuel (for example fuel oil) is a gasoline.Gasoline is volatile fuel, and the fuel in the fuel tank can volatilize very soon increases the pressure of fuel tank internal, when pressure arrives certain value, will produce certain danger, comes this pressure of balance so people have found out the whole bag of tricks.Originally be that fuel tank cap has been made pressure-limit valve, when pressure exceeded a certain value, pressure-limit valve was just opened, and was discharged to gasoline vapour in the atmosphere.Afterwards, people set out from the fuel saving and the angle of protection environment, were provided with the fuel fume temporary storing device, for example the charcoal jar.
The charcoal jar is a part that is under the jurisdiction of the fuel fume control system, and this system fuel fume behind the engine stoping operation escapes into atmosphere and is introduced into.From nineteen ninety-five, China stipulates that all automobiles that newly dispatch from the factory must possess this system.
In general, charcoal jar inside is filled by the very strong active carbon of adsorptivity, and fuel fume unnecessary in the fuel tank no longer is discharged in the atmosphere, but introduces active carbon charcoal jar by a pipe.The active carbon adsorption fuel fume; In the time of start; Active carbon charcoal jar solenoid valve is opened in good time, and the gasoline vapour in the active carbon charcoal jar is brought into participation burning in the cylinder by fresh air under the degree of vacuum effect of intake manifold, thereby has realized the purpose of fuel saving and environmental protection.
In recent years, the research of hybrid vehicle develops rapidly, and the research of the fuel fume control system of hybrid vehicle and design have also run into new problem.Hybrid vehicle for example; Plug-in hybrid-power automobile particularly; When cruising, adopt pure power mode to go basically, this moment, motor was not worked, and can't clean the charcoal jar yet; But the fuel of fuel tank the inside can produce fuel fume incessantly, and the generation meeting of steam gets more and more along with temperature, time and motion.After increasing steam got into the charcoal jar, in case the charcoal jar is filled, then unnecessary steam can only be discharged to the atmosphere from the atmosphere entry of charcoal jar, and this is befouling environment not only, also can make client smell the taste of gasoline simultaneously, produces strong complaint and worry.
[model utility content]
The problem that the utility model will solve provides a kind of fuel fume control system, and it has overcome hybrid vehicle fuel fume temporary storing device under electric drive mode and has been filled back fuel and escapes in the atmosphere and then pollute and influence riding etc. shortcoming.

First aspect according to the utility model provides a kind of fuel fume control system that is used for hybrid vehicle, and at least one power source of said hybrid vehicle is an internal-combustion engine,
Wherein,
Said fuel fume control system comprises the fuel fume temporary storing device, and said fuel fume temporary storing device is communicated with the fuel tank of said internal-combustion engine, is communicated with the cylinder intake manifold of said internal-combustion engine simultaneously,
Said fuel fume control system also comprises Weight-measuring device; It is used to measure the weight of said fuel fume temporary storing device, and said Weight-measuring device is communicated by letter with the fuel fume temporary storing device cleaning controller of said fuel fume control system and is connected.
Through the fuel fume control system of such setting, the fuel in its fuel tank (for example fuel oil) can automatically flow into after evaporation in the cylinder that can enter into internal-combustion engine in the fuel fume temporary storing device, after filling with in the fuel fume storage device again through intake manifold and carry out work done.The fuel fume temporary storing device can stored fuel fume be transported to the work done of burning in the cylinder of internal-combustion engine through intake manifold when specifically, can receive and store from the fuel fume of said fuel tank, at internal combustion engine start when internal-combustion engine is not worked.The advantage that the fuel fume control system that is provided with so also has is when fuel fume temporary storing device cleaning controller judges that the measured value of Weight-measuring device surpasses limit value, to think that the fuel fume in the fuel fume temporary storing device is full; Then starting apparatus combustion engine cleans said fuel fume temporary storing device, in order to avoid slattern fuel fume or make it flow into the discomfort that causes the occupant in atmosphere or the passenger cabin.
Alternatively, in foregoing fuel fume control system, said fuel is gasoline.In the fuel fume control system that is provided with like this, gasoline has good vapo(u)rability and flammability, can guarantee that engine running is steady, burning is complete, carbon deposit is few.
Alternatively, in foregoing fuel fume control system, said fuel fume temporary storing device is the charcoal jar.In the fuel fume control system that is provided with like this, the sorbent that is provided with in the fuel fume temporary storing device is an active carbon etc., its excellent adsorption, can realize good storage effect.
Alternatively, in foregoing fuel fume control system, the top of said fuel fume temporary storing device place is provided with overfall, and this overfall is preferably and connects atmospheric air port.
Second aspect according to the utility model provides a kind of hybrid vehicle, and it comprises like one in preceding described fuel fume control system.Can understand, also have corresponding aforementioned advantages through the hybrid vehicle that is provided with like this.
