Problems solved by technology

[0005] However, when the filter is contaminated or the pump fails, there is a problem of opening the fuel tank and draining the fuel
In particular, when the internal filter is replaced, oxygen can flow into the fuel tank causing it to corrode

Embodiment Construction

[0018] A typical embodiment of the present invention will be described in detail below with reference to the accompanying drawings.

[0019] figure 1 is a schematic diagram of a liquefied petroleum injection fuel supply system according to an exemplary embodiment of the present invention.

[0020] refer to figure 1 The liquefied petroleum injection fuel supply system includes an engine 100, a pressure regulating valve 105, a return pipeline 110, a multi-valve 112, a delivery pipe 115, a pipeline filter 117, an electronic control unit 120, a pump driver 125, a bracket 130, and a return valve 132 , fuel tank 135 , first and second brackets 140 a and 140 b , reservoir 150 , fuel pump 155 , pre-filter 160 , and external filter 165 .

[0021] The bracket 130 and the pump driver 125 are installed on the upper portion of the fuel tank 135 , and the reservoir 150 is disposed inside the fuel tank 135 . The fuel pump 155 is installed inside the reservoir 150 , and the pre-filter 160 ...

Abstract

The present invention relates to a liquefied petroleum fuel-injection feeding system for feeding liquefied petroleum gas fuel to an engine, which can comprises a fuel tank filled with liquefied petroleum gas, a pump device arranged at the inner part of the fuel tank and used for feeding liquefied petroleum gas fuel to an engine, and an outer filter arranged at the outer part of the fuel tank and used for filtering foreign matters when the liquefied petroleum gas fuel is adsorbed into the pump device. Therefore, the outer filter can be changed without opening the fuel tank. In addition, when the outer filter is changed, a first valve and a second valve are closed so that the fuel in the container can not be discharged to the outer part. In addition, a suction pipeline is inserted into a prefilter, thereby reducing the suction resistance. Furthermore, the suction pipeline is separated, and the separated parts are connected by flexible tubes, thereby preventing the vibration and noise generated by the pump from being transferred to the fuel tank.

Description

[0001] Cross References to Related Applications [0001] This application claims priority and benefit from Korean Patent Application No. 10-2008-0072457 filed with the Korean Intellectual Property Office on July 24, 2008, the entire contents of which are incorporated herein by reference. technical field [0002] The present invention relates to a liquefied petroleum injection (LPI) fuel supply system, and more particularly to a liquefied petroleum injection fuel supply system equipped with a filter for filtering foreign matter in liquefied petroleum gas (LPG). Background technique [0003] In general, an engine equipped with a liquefied petroleum injection system can generate a large power with a small amount of pollutants, and thus the system can be used in a vehicle. [0004] A fuel pump is installed at a lower portion inside the fuel tank to suck in liquid fuel and supply the liquid fuel to the engine, and a filter is provided at its suction port to filter foreign matter....
