As the preferred scheme of one, described temperature monitoring sensor is arranged between stop valve and excess flow valve.
As the preferred scheme of one, describedly comprise from ascending pipe from pressure charging system, should be connected in boost port from ascending pipe one end, the other end is communicated with the liquid Space of LNG car bottle, should be communicated with from the gas-phase space of boost port with LNG car bottle, on ascending pipe, be provided with self-pressure evaporator.
As the preferred scheme of one, described LNG car bottle is also provided with supercharging liquid outlet, should be communicated with supercharging liquid outlet from the other end of ascending pipe.
As the preferred scheme of one, the entrance of described self-pressure evaporator is communicated with by subsidiary conduit with between the outlet of fluid carburetor.
After have employed technique scheme, effect of the present utility model is: due to a kind of automatic TME of LNG car bottle, described LNG car bottle is provided with filling opening, liquid outlet and from boost port, this filling opening connects liquid feeding pipeline, this liquid outlet connects liquid outlet system, should connect from pressure charging system from boost port, described automatic TME also comprises temperature monitoring sensor, the stop valve that this liquid outlet system comprises fluid pipeline and arranges in turn according to LNG fluid flow direction, excess flow valve, fluid carburetor, decompression regulating valve, surge tank and solenoid valve, this temperature monitoring sensor to be installed on fluid pipeline and between liquid outlet and the entrance of fluid carburetor, this temperature monitoring sensor is electrically connected with switching controller, this switching controller and the temperature indicator list catenation be arranged in vehicle cab, during this LNG car bottle air feed normal to engine, liquified natural gas flows out from liquid outlet, monitored by temperature monitoring sensor after stop valve and excess flow valve, in the temperature obtained and LNG car bottle, temperature is almost close, and temperature monitoring sensor be arranged on car bottle outside can convenient for maintaining, also convenient rectification, without the need to changing car bottle.And driver just can observe the temperature of temperature display meter display intuitively in driving cabin, thus can judge whether LNG's is the saturated liquid being greater than 0.8MPa, reducing the dispute between driver and gas station, also facilitating when occurring being short of power driver to judge the concrete reason of vehicle simultaneously.
Again due to described the liquid location display being provided with Temperature displaying window, this temperature display meter is arranged in Temperature displaying window, by the liquid location display and temperature display meter integrated, reduce metered quantity in pilothouse.
Again because described temperature monitoring sensor is arranged between stop valve and excess flow valve, convenient when replacing or maintenance temperature monitoring sensor.
Comprise from ascending pipe due to described from pressure charging system again, should be connected in boost port from ascending pipe one end, the other end is communicated with the liquid Space of LNG car bottle, should be communicated with, and be provided with stop valve and self-pressure evaporator on ascending pipe from the gas-phase space of boost port with LNG car bottle.The entrance of described self-pressure evaporator is communicated with by subsidiary conduit with between the outlet of fluid carburetor.Like this, in extremely cold area, when vehicle does not start, coolant-temperature gage in fluid carburetor is lower and do not circulate, and possible gasification result is poor, can only be supplied to engine and cannot carry out from supercharging, now, utilize self-pressure evaporator additional mechanical supercharging, make pressurized effect more stable.
