일반적으로 자동차의 연료는 여러 가지가 있지만 그중 저발열량과 옥탄가가 높고 가격이 싸다는 장점으로 인해 영업용 택시나 소형 트럭 등 영업용 차에는 액화석유가스(LPG)를 연료로 사용한다.Generally, there are various fuels for automobiles, but LPG is used as fuel for commercial vehicles such as commercial taxis and light trucks because of low calorific value, high octane price and low price.

이러한 LPG를 이용하는 차량은, LP가스가 상온에서 2 - 8kgf/cm2의 압력으로 액화 충전되어 있는 연료탱크와, 상기 연료 탱크에 충전된 연료를 펌핑하여 압력을 높이는 펌프와, 상기 펌프에서 펌핑된 고압 연료의 압력을 조정하는 압력 조정 밸브와, 상기 압력 조정 밸브를 통한 연료를 기화시키는 베이퍼라이저를 포함하는 엔진부로 이루어져, 연료 탱크에 액화 충전된 연료를 펌프는 펌핑하여 고압의 연료로 압력 조정 밸브에 전달한다.A vehicle using the LPG includes a fuel tank in which LP gas is liquefied and charged at a pressure of 2-8 kgf / cm 2 at room temperature, a pump for pumping up the fuel charged in the fuel tank to increase pressure, and a pump pumped from the pump. It consists of an engine portion including a pressure regulating valve for adjusting the pressure of the high pressure fuel, and a vaporizer for vaporizing the fuel through the pressure regulating valve, the pump pumps the fuel liquefied and filled in the fuel tank to the pressure regulating valve as a high pressure fuel To pass.

그러면 압력 조정 밸브는 그 펌핑된 연료의 압력을 조정한 후 엔진부로 유입시키게 되고, 엔진부내의 베이퍼라이저는 그 연료를 기화시킨 후 공기와 혼합하여 엔진을 구동하게 된다.The pressure regulating valve then adjusts the pressure of the pumped fuel and flows it into the engine section, and the vaporizer in the engine section vaporizes the fuel and mixes it with air to drive the engine.

그런데 이러한 종래의 LPG차량은 연료가 누출되는 것을 감지하는 장치가 별도로 구비되어 있지 않아 연료 누출로 인한 화재등의 위험이 있었다.However, such a conventional LPG vehicle is not provided with a separate device for detecting the leakage of fuel, there was a risk of fire due to fuel leakage.

[고안이이루고자하는기술적과제][Technical Challenges to be Done]

따라서 본 고안의 목적은 상기와 같은 문제점을 해결하기 위한 것으로서, 연료 라인의 압력을 체크하여 이상 발생시 연료누출을 경고해주어 연료누출로 인한 화재나 기타 위험을 미연에 방지하도록 한 LPG차량의 연료누출 경고장치를 제공하는데 있다.Therefore, the object of the present invention is to solve the above problems, and checks the pressure of the fuel line to warn the fuel leakage in the event of an abnormality, the fuel leakage warning of LPG vehicles to prevent fire or other risks due to fuel leakage in advance. To provide a device.

이와 같은 본 고안의 목적은,연료 탱크로부터 토출되는 연료가 엔진에 도달시 각 연료라인에 구비되어 압력을 검출하는 다수개의 압력센서와; 상기 다수개의 압력센서로 부터 각각 검출되는 각 연료라인의 압력값을 검색하여 연료누출 여부를 판별하고 연료압의 이상시 연료누출 경고를 위한 제어신호를 발생하는 전자제어모듈과; 상기 전자제어모듈로 부터 출력되는 경고 제어신호에 따라 연료 누출을 경고해주는 연료누출 경고부를 구비함으로써 달성되는 것이다.An object of the present invention, a plurality of pressure sensors provided in each fuel line when the fuel discharged from the fuel tank reaches the engine and detects the pressure; An electronic control module for retrieving fuel leakage by searching pressure values of respective fuel lines respectively detected by the plurality of pressure sensors and generating a control signal for warning of fuel leakage in case of abnormal fuel pressure; It is achieved by having a fuel leakage warning unit for warning the fuel leakage in accordance with the warning control signal output from the electronic control module.

[고안의구성및작용][Composition and Action of Design]

이하 본 고안의 목적을 효과적으로 달성할 수 있는 바람직한 실시 예로서 그 기술 구성 및 작용 효과를 첨부한 별첨의 도면에 의해 상세히 설명하면 다음과 같다.Hereinafter, the present invention will be described in detail with reference to the accompanying drawings, which are attached to the technical configuration and the effect of the present invention.

도1은 본 고안에 따른 LPG차량의 연료누출 경고장치 구성도로서 이에 도시된 바와같이, 연료 탱크(10)로부터 토출되는 연료의 압력을 조정하는 압력조절부(50)와, 상기 압력조절부(50)에서 얻어지는 연료를 기화시켜 구동하는 엔진부(60)와, 상기 연료 탱크(10)와 엔진부(60)사이의 각 연료라인에 구비되어 연료압을 검출하는 다수개의 압력센서(20 - 40)와, 상기 다수개의 압력센서(20 - 40)로부터 각각 검출되는 각 연료라인의 압력값을 검색하여 연료누출 여부를 판별하고 연료압의 이상시 연료누출 경고를 위한 제어신호를 발생하는 전자제어모듈(70)과, 상기 전자제어모듈(70)로 부터 출력되는 경고 제어신호에 따라 연료 누출을 경고해주는 연료누출 경고부(80)로 구성 되었다.1 is a block diagram of a fuel leakage warning device for an LPG vehicle according to the present invention, as shown therein, a pressure regulating unit 50 for adjusting a pressure of fuel discharged from a fuel tank 10 and the pressure regulating unit ( Engine unit 60 for vaporizing and driving the fuel obtained from 50, and a plurality of pressure sensors (20-40) provided in each fuel line between the fuel tank 10 and the engine unit 60 to detect the fuel pressure. And an electronic control module for determining fuel leakage by searching pressure values of respective fuel lines detected from the plurality of pressure sensors 20-40, and generating a control signal for warning of fuel leakage in case of abnormal fuel pressure. 70, and a fuel leakage warning unit 80 for warning the fuel leakage in accordance with the warning control signal output from the electronic control module 70.

이와 같이 구성된 본 고안에 의한 연료누출 경고장치는, 먼저 연료탱크(10)로부터 토출되는 연료는 압력조절부(50)에 의해 감압된 후 엔진부(60)에 공급되어 엔진이 구동되도록 한다.In the fuel leakage warning device according to the present invention configured as described above, the fuel discharged from the fuel tank 10 is first reduced in pressure by the pressure regulating unit 50 and then supplied to the engine unit 60 to drive the engine.

이때, 연료탱크(10)와 엔진부(60)까지의 각 연료 공급라인에 각각 구비된 압력센서(20 - 40)는 해당 라인으로 공급되는 연료압을 측정하여 전자제어모듈(70)에 전달한다.At this time, the pressure sensor 20 to 40 respectively provided in each fuel supply line to the fuel tank 10 and the engine unit 60 measures the fuel pressure supplied to the corresponding line and transmits it to the electronic control module 70. .

그러면 전자제어모듈(70)은 각각의 압력센서(20 - 40)로 부터 각각 검출되는 압력값과 그 연료라인의 정상적인 압력값을 비교하여 연료누출 여부를 판별한다.Then, the electronic control module 70 compares the pressure value detected from each pressure sensor 20-40 with the normal pressure value of the fuel line to determine whether the fuel is leaked.

즉, 전자제어모듈(70)은 제1압력센서(20)로부터 검출되는 연료압과 그 압력센서가 설치된 라인의 정상적인 연료압을 비교하여 연료압의 이상유무를 판별하게 되고, 아울러 제2압력센서(30)로부터 검출되는 연료압과 그 압력센서가 설치된 라인의 정상적인 연료압을 비교하여 연료압의 이상유무를 판별하게 되며, 마찬가지로 제3압력센서(40)로부터 검출되는 연료압과 그 압력센서가 설치된 라인의 정상적인 연료압을 비교하여 연료압의 이상유무를 판별하게 된다.That is, the electronic control module 70 compares the fuel pressure detected from the first pressure sensor 20 with the normal fuel pressure of the line in which the pressure sensor is installed to determine whether the fuel pressure is abnormal, and the second pressure sensor The fuel pressure detected from 30 is compared with the normal fuel pressure of the line on which the pressure sensor is installed to determine whether the fuel pressure is abnormal. Similarly, the fuel pressure detected from the third pressure sensor 40 and the pressure sensor are determined. By comparing the normal fuel pressure of the installed line to determine the abnormality of the fuel pressure.

이 판별결과 검출되는 연료압과 그 라인의 정상적인 연료압과의 차이가 발생하면 연료압의 이상으로 판별을 하고, 연료누출 경고부(80)에 경고 제어신호를 발생한다.If a difference between the fuel pressure detected as a result of the discrimination and the normal fuel pressure of the line occurs, it is discriminated as an abnormality of the fuel pressure, and a warning control signal is generated in the fuel leakage warning unit 80.

그러면 연료누출 경고부(80)는 경고등을 발광시키거나 경고음을 송출하여 사용자에게 연료에 이상이 발생했음을 알려주게 되는 것이다.Then, the fuel leakage warning unit 80 emits a warning light or emits a warning sound to inform the user that an abnormality has occurred in the fuel.

[고안의효과][Effect of design]

이상에서 상술한 바와 같이 본 고안은 연료탱크로부터 토출되는 연료가 엔진에 공급될때까지의 각 연료라인의 연료압을 검출하여 이상유무를 판별하고 연료압 이상시 사용자에게 연료압 이상을 경고해줌으로써 연료누출로 인한 화재나 기타 대형사고를 미연에 방지할 수 있는 효과가 있다.As described above, the present invention detects the fuel pressure of each fuel line until the fuel discharged from the fuel tank is supplied to the engine, determines whether there is an abnormality, and warns the user of the fuel pressure abnormality when the fuel pressure is abnormal. It is effective to prevent fire or other large accidents caused by leakage.
