Abstract

PROBLEM TO BE SOLVED: To stably and forcibly supply low boiling point fuel to a fuel injection pump by providing a fuel feeding pump which is connected to a pressure container for filling liquefied low boiling point fuel and which is driven by blowing and discharging of a compressed fluid, and a valve mechanism for opening/ closing a fuel supplying pipe passage interlocking with start and stop of an engine. SOLUTION: When compressed air is led to an operating gas chamber 22 of a fuel feeding pump, a piston 24 in the operating gas chamber 22 is moved to a left direction, and a piston 23 of a combustion chamber 21 connected to the piston 24 is also moved to a left direction. As a result, fuel in a left chamber side of the fuel chamber 21 is discharged, and fuel is sucked to a right chamber side. After communication of the operating gas chamber 22 with an air compressor is shut out, when the operating gas chamber 22 is communicated with an outside field, pressure air of the operating gas chamber 22 is released to the outside. As a result, the piston 22 is moved to a right direction, and fuel of right chamber side of the fuel chamber 21 is moved to a left chamber side passing a connecting pipe 27. It is thus possible to increase pressure of fuel without being brought into contact operating gas with fuel.

However, since DME fuel has a low boiling point of about -25 ° C., it is a gas at room temperature, and must be supplied under pressure above the vapor pressure in order to be used as a high-density liquid fuel for diesel engines. There is. Further, since the temperature inside the fuel injection pump rises during operation of the diesel engine, even if the fuel temperature or the fuel ambient temperature at the injection pump rises, the fuel is kept at a pressure at which a low boiling point fuel such as DME keeps a liquid. Need to be pressurized. It is considered that the temperature of the injection pump during the operation of the engine is increased to at least 60 to 70 degrees Celsius, and even in such a situation, it is necessary to feed oil under a pressure of 15 kgf / cm 2 or more in order for DME to be a liquid. .

For example, it is possible to use a double-acting piston in which both the compressed gas and the fuel are taken in and out of the fuel feed pump by a piston, and adjust the degree of pressure increase by the area ratio of the two pistons. In addition to increasing the pressure, it is desirable to increase the pressure to a constant pressure.
The pressure should be increased to at least kgf / cm 2 , preferably at least 20 kgf / cm 2 . On the other hand, the upper limit of the pressure is 50 kgf / cm 2 or less, preferably 30 kgf / cm 2 from a practical viewpoint.
cm 2 or less is appropriate. This fuel feed pump is preferably a piston type, and a rotary type is not suitable.
As a compressed gas as a driving source, a large truck or the like is generally equipped with an air compressor, so that the compressed air may be used. When an air compressor is not provided, a high-pressure gas cylinder of air, nitrogen, helium, or the like can be mounted and used as a compressed gas.
