The structural representation of the system controlling fuel tank internal gas pressure that Fig. 1 provides for the application one embodiment.Such as Fig. 1 institute
Showing, this system mainly may include that to accommodate the fuel tank 11 of fuel (such as gasoline), in order to the combustion chamber of combusting said fuel
10 (in electromotors), are connected to the fuel feed line 12 between above-mentioned fuel tank 11 and combustion chamber 10 and fuel return line
14, it is arranged at the pump 13 in above-mentioned fuel feed line 12, is arranged at the fuel valve 15 in above-mentioned fuel return line 14, with
And heat-exchange system (Heating, Ventilation and Air Conditioning, HVAC) 30.Wherein, in normal work
State, above-mentioned fuel valve 15 is closed, and the most above-mentioned fuel feed line 12 is for by defeated for the fuel in fuel tank 11
Deliver to combustion chamber 10 burns.
Above-mentioned heat-exchange system 30 may include that compressor 31, condenser 32, vaporizer 33 and coolant valve 34.Heat
The basic functional principle of exchange system 30 is substantially: by compressor 31, by the gaseous coolant of low-temp low-pressure at preservation of energy
In the case of, it being compressed into the gas of high pressure-temperature, and transmit to above-mentioned condenser 32, the gas of high pressure-temperature is cold in condenser 32
Needing during Ning to discharge substantial amounts of heat, become the liquid refrigerants of normal temperature high voltage, the coolant of liquid high pressure enters vaporizer 33,
Space increases suddenly, and pressure reduces, and the coolant of liquid will vaporize, and becomes the coolant of gaseous state low temperature, thus absorbs substantial amounts of heat
Amount, vaporizer 33 will turn cold.Wherein, heat-exchange system 30 is technology well known to those of ordinary skill in the art, the most not
Repeated again.It should be noted that above-mentioned heat-exchange system 30 can be the air conditioning system of configuration on automobile, it is also possible to be special
Door is for the heat-exchange system lowering the temperature the fuel vapour in fuel tank.
In the embodiment of the present application, for realizing the control to the air pressure in fuel tank, one can be arranged in above-mentioned fuel tank
Baroceptor (not shown), this baroceptor is for detecting the atmospheric pressure value in described fuel tank.Further, by described heat exchange
The vaporizer 33 of system 30 is arranged in above-mentioned fuel feed line 12 or fuel return line 14, for described fuel tank 11
Interior fuel vapour is lowered the temperature.Additionally, said system also needs to include a controller, this controller at least in order to control on
State the operation of heat-exchange system, and control being turned on and off of said pump 13 and fuel valve 15.This controller can be to appoint
The logic circuit of meaning form or microprocessor (MCU) etc..
The work process of said system approximately as:
First, by the atmospheric pressure value in baroceptor detection fuel tank and the atmospheric pressure value detected is fed back to above-mentioned control
Device, controller, after the atmospheric pressure value receiving detection, needs to judge that whether the atmospheric pressure value detected is more than preset pressure threshold value
(generally this preset pressure threshold value is the most safer air pressure extreme value), if being more than, then in showing above-mentioned fuel tank 11
Air pressure is the most dangerous, and need to take to reduce pressure accordingly measure.The factor of the rising of above-mentioned atmospheric pressure value may include that outside air temperature
Raise or the jolting of vehicle travel process.Finally, controller noted above can trigger by the way of sending enabled instruction
State the unlatching of heat-exchange system 30, and pump 13 and the unlatching of fuel valve 15.Wherein, pump 13 is by the fuel in fuel tank 11

Fuel return after steam is condensed is transported in above-mentioned fuel tank 11.It should be noted that the position of above-mentioned combustion chamber 10 can
With higher than this fuel feed line 12 and fuel return line 14, such that it is able to guarantee when above-mentioned fuel valve 15 is opened
Waiting, fuel will not enter in above-mentioned combustion chamber 10, but can be transported to fuel tank 11 (formation circulation line).
Controller noted above can after above-mentioned heat-exchange system 30 opens one section of duration, control this heat-exchange system 30,
Said pump 13, the closedown of fuel valve 15.Certainly, controller can also be by receiving the air pressure of baroceptor Real-time Feedback
Value, and the atmospheric pressure value in above-mentioned fuel tank is reduced to certain safe atmospheric pressure value, and (this safe atmospheric pressure value can be less than above-mentioned pre-
If air pressure threshold value) time, control above-mentioned heat-exchange system 30, said pump 13, the closedown of fuel valve 15.
It is noted that in other embodiments of the application, the vaporizer 33 of above-mentioned heat-exchange system 30 can be set
It is placed in described fuel tank 11, so, when the atmospheric pressure value detected in fuel tank 11 is higher than preset pressure threshold value when, then may be used
With directly by opening this heat-exchange system 30, the fuel vapour in above-mentioned fuel tank 11 is lowered the temperature, thus reach fall
The effect of pressure.On the premise of vaporizer 33 is arranged in described fuel tank 11, the fuel return pipe that a upper embodiment is mentioned
Road 14, fuel valve 15 all can be removed, thus the structure of simplified system, reduce manufacturing cost to a certain extent.
In another embodiment of the application, owing in most of the cases, hot conditions can cause the rising of air pressure,
Therefore, above-mentioned baroceptor can be substituted by temperature sensor, thus by detecting the temperature in described fuel tank, and pass through
When controller judges that whether temperature that described temperature sensor detects is more than preset temperature threshold value, more than time, trigger described
The unlatching of heat-exchange system.
The flow process of the method controlling fuel tank internal gas pressure that Fig. 2 provides for the application one embodiment, including:
Atmospheric pressure value in S101: baroceptor detection fuel tank.
S102: controller receives the atmospheric pressure value that described baroceptor detects.
S103: controller judges that whether the described atmospheric pressure value detected is more than preset pressure threshold value.
S104: if the described atmospheric pressure value detected is more than preset pressure threshold value, then trigger the unlatching of heat-exchange system, to institute
The fuel vapour stated in fuel tank is lowered the temperature.
In the application one optional embodiment, described method also comprises the steps:
Controller, when the described atmospheric pressure value detected is more than preset pressure threshold value, triggers pump and the unlatching of fuel valve.
In the application one optional embodiment, the vaporizer of described heat-exchange system is arranged in described fuel tank.
In sum, the application can detected by the atmospheric pressure value (or temperature) in detection fuel tank, controller
When atmospheric pressure value (or temperature) is more than preset pressure threshold value (or preset temperature threshold value), trigger the unlatching of heat-exchange system, with to institute
The fuel vapour stated in fuel tank is lowered the temperature, thus reduces the air pressure in described fuel tank by temperature-fall period.Can see
