    [Objective of the invention]
    The present invention relates to the prevention of rapid temperature drop of LPG vehicles, and more particularly, the rapid drop in temperature due to the adiabatic expansion of the gas in the fuel supply line due to the large pressure difference at the time of filling the gas container with high pressure gas. LPG vehicle's rapid temperature drop prevention device to improve the durability of fuel supply line by greatly reducing the temperature change caused by adiabatic expansion during gas filling by preventing the rapid rise of temperature by post compression process. It is about to provide.
    [Technical Field to which the Invention belongs and Conventional Technology in the Field]
    In general, LPG vehicles use a mixer and a vaporizer to supply fuel to the combustion chamber.
    In other words, the vaporizer in the LPG vehicle converts the LPG of the liquid into gas LPG by depressurizing the liquid, which maintains the pressure to adjust the amount of vaporization according to the increase or decrease of the load of the engine.
    Using only LPG gas saturated in LPG cylinder can improve the start-up in cold weather. However, at high speed, LPG is not enough for the engine. Supply gas LPG.
    Then, the mixer is to mix the air and LPG in approximately 15: 3 to supply to each cylinder, which is to mix the LPG vaporized in the vaporizer with air to supply to each cylinder.
    In such an LPG vehicle, when a high pressure LPG gas is charged into a gas container at a filling station, a temperature drop occurs due to adiabatic expansion of the gas in the fuel supply line because the pressure difference is large. And, at the beginning of charging, it usually falls more than -80 o C.
    In addition, when the gas is charged to some extent and the compression process is reached, the temperature rises above the atmospheric temperature.
    If the charging process is repeated in a natural gas vehicle or the like, there is a concern that the fuel supply line may be damaged due to thermal stress.
    [Technical Challenges to Invent]
    Accordingly, an object of the present invention is to consider the conventional problems as described above, the pressure difference is initially large when the high-pressure gas is filled in the container, the rapid drop in temperature due to the adiabatic expansion of the gas in the fuel supply line and the compression after filling It is to provide a rapid temperature drop prevention device of the LPG vehicle to prevent the rapid rise of temperature by.
    Another object of the present invention is to prevent the rapid drop in temperature due to the adiabatic expansion of the gas in the fuel supply line and the rapid rise in temperature due to the compression process after filling the high pressure gas in the gas container due to the large pressure difference initially. In order to improve the durability of the fuel supply line by placing an orifice in the fuel cylinder, the temperature change due to adiabatic expansion during gas filling is greatly reduced.
    An object of the present invention as described above is a fuel supply line for supplying a high-pressure gas flowing through the filling port; A valve installed at the fuel supply line to control supply of fuel; It can be achieved by constructing an orifice installed in the fuel cylinder and injecting the high pressure gas supplied from the fuel supply line to the fuel cylinder.
    In order to prevent the rapid drop in temperature due to the adiabatic expansion of the gas in the fuel supply line and the rapid rise in temperature due to the compression process after filling, the present invention has a large pressure difference at the time of filling the high pressure gas into the fuel cylinder. By installing the orifice in the fuel cylinder, the temperature change due to adiabatic expansion during gas filling is greatly reduced, thereby improving the durability of the fuel supply line, thereby achieving the above object.
    Composition and Action of the Invention
    Hereinafter, described in detail with reference to the accompanying drawings the technical configuration and effect as a preferred embodiment that can effectively achieve the object of the present invention.
    1 is a block diagram showing a rapid temperature drop prevention device of the present invention LPG vehicle as shown in the present invention is a charging port 101 for the high-pressure gas inlet; A fuel supply line 102 which is coupled to the filling port 101 and supplies high-pressure gas introduced thereto; A fitting 104 connecting the fuel supply line 102; An orifice 105 connected to the fitting 104 and installed in the fuel cylinder 100 to inject a high pressure gas supplied through the fuel supply line 102 and the fitting 104 to the fuel cylinder 100; ; The valve 103 is installed in the fuel supply line 102 to control the gas of the orifice 105 and the fuel supply line 102 to supply the engine when the high-pressure gas is filled in the fuel cylinder 100 It consists of.
    In the above, the orifice 105 is preferably smaller than the smallest diameter of the fuel supply line 102.
    According to the present invention configured as described above, when the high pressure gas is charged into the gas container, that is, the fuel cylinder 100 through the filling port 101, the high pressure gas is initially supplied to the fuel supply line 102 and the fitting 104. Through the orifice 105 is installed at the end of the fuel supply line 102 in the fuel cylinder 100 through the fuel cylinder 100 through the high pressure gas through the orifice 105 100 is supplied by injection.
    In the above, since the diameter of the orifice 105 is smaller than the smallest diameter of the fuel supply line 102, since the thermal insulation flat process of the gas in the initial fuel supply line 102 is concentrated toward the orifice 105, the fuel supply line At 102, the change in temperature is greatly reduced.
    As such, when the high pressure gas is completely filled in the fuel cylinder 100, the high pressure gas is again supplied to the control of the valve 103 through the orifice 105, the fitting 104, and the fuel supply line 102. To the engine.
    As described above, in the present invention, when the high-pressure gas is charged to the fuel cylinder 100, the pressure difference is large at the initial stage, so that the temperature is rapidly reduced by the adiabatic expansion of the gas in the fuel supply line 102 and the temperature by the compression after the filling process. In order to prevent the rapid rise of the orifice, by installing the orifice 105 in the fuel cylinder 100, the temperature change due to adiabatic expansion during gas filling by the orifice 105 is greatly reduced, resulting in the It can be seen that the durability is improved.
    [Effects of the Invention]
    As described above, the present invention prevents the rapid drop in temperature due to the adiabatic expansion of the gas in the fuel supply line and the rapid rise in temperature due to the compression process after filling, because the pressure difference is large at the time of filling the high pressure gas into the container. It is a very useful invention that the durability of the fuel supply line is always.
