易い欠点があつた。(b) Prior art and problems to be solved Generally, automobile engines use liquefied petroleum gas, which is mainly composed of propane and has a low evaporation temperature of around -40 degrees Celsius, that is, it evaporates easily. The engine uses liquefied petroleum gas, which is commercially available for use in portable gas stoves and is mainly composed of butane, with an evaporation temperature close to -7 degrees Celsius, which is close to room temperature. There was a simple drawback.

を安定して運転することが困難となつていた。 Conventionally, this type of small portable engine fuel supply system is provided with a pressure regulation chamber that reduces the pressure of liquid fuel to a predetermined pressure and vaporizes it, and communicates with this pressure regulation chamber to supply fuel to the engine. It was equipped with a metering chamber that sensed the intake negative pressure and adjusted the flow rate of vaporized fuel, and a mixer that mixed the metered fuel into the air and supplied it to the engine. A pressure regulating valve is provided that communicates with a fuel container that stores fuel and opens and closes a fuel passage that communicates this pressure regulating chamber and the fuel container in conjunction with a diaphragm provided in this pressure regulating chamber. The pressure of the vaporized fuel is vaporized in the pressure regulating chamber, and when the pressure of the vaporized fuel is detected and exceeds a predetermined pressure, the passage of liquid fuel from the fuel container to the pressure regulating chamber is closed by the pressure regulating valve. After reducing the pressure of the liquid fuel that passed through the engine, it was vaporized in a pressure regulating chamber, and the vaporized fuel was mixed with air in a mixer through a metering chamber and supplied to the engine.
In this conventional configuration, the pressure of the vaporized fuel is sensed, and the pressure of the liquid fuel before vaporization is reduced and adjusted by a pressure regulating valve to maintain the pressure of the vaporized fuel at a constant level. Also, since the fuel uses liquefied gas mainly composed of butane, even if the liquid fuel is slightly adjusted, it expands greatly during vaporization, and the liquid fuel that vaporizes and mixes into the fuel. As the pressure vaporizes further, fluctuations become large, making it difficult to maintain accurate and stable pressure, making it difficult to operate the engine stably.

ものである。(c) Means and operation for solving the problem The present invention provides a vaporization chamber that removably communicates with a discharge port of a fuel container storing liquefied petroleum gas fuel and vaporizes liquid fuel supplied from the fuel container. The pressure regulating valve communicates with this vaporizing chamber via a pressure regulating chamber passage, senses the pressure of the vaporized fuel, and operates in the direction of closing the pressure regulating chamber passage against the bullet. A pressure regulating chamber is provided to adjust the flow rate of the fuel to reduce and maintain a predetermined pressure, and the vaporized fuel whose pressure is regulated in the pressure regulating chamber is metered in the metering chamber according to the intake negative pressure. The fuel is mixed with air in a mixer and then supplied to the engine, and the flow rate of the fuel after it has been vaporized in the vaporization chamber is adjusted to reduce the pressure, so there is less pressure fluctuation in the vaporized fuel and engine operation is improved. It is stable.
