Description
본 고안은 디젤 차량에서의 연료 차단장치에 관한 것으로서, 특히 연료탱크의 연료파이프중 일부가 단락되거나 크랙이 발생하여 연료가 누출되어 연료소비량이 증가할 때 이를 감지하여 연료의 출력을 차단함으로서, 연료의 손실을 최소한으로 줄일 수 있도록 한 연료 차단장치에 관한 것이다.The present invention relates to a fuel cut-off device in a diesel vehicle, and in particular, when a portion of the fuel pipe of the fuel tank is shorted or cracked, the fuel leaks and the fuel consumption is increased to cut off the output of the fuel. A fuel shutoff device is provided to minimize the loss of fuel.
일반적으로 디젤기관에서는 6개의 연료탱크로부터 엔진까지 연료를 공급하는 연료파이프가 길게 연결되어 있는 구조를 갖고 있다.In general, a diesel engine has a structure in which fuel pipes supplying fuel from six fuel tanks to an engine are long connected.
종래에는 연료탱크로부터 엔진까지 길게 연결된 연료파이프중 일부가 단락되거나 크랙이 발생하게 되면 연료가 밖으로 누출되어 화재의 위험이 있을 뿐만 아니라 연료소비량이 급증하게 되는 문제점이 있었다.Conventionally, when some of the fuel pipes connected from the fuel tank to the engine are short-circuited or cracked, fuel leaks out, causing a risk of fire as well as a sharp increase in fuel consumption.
따라서, 상기 문제점을 해결하기 위한 본 고안은 연료탱크의 연료파이프중 일부가 단락되거나 크랙이 발생하여 연료가 누출되어 연료소비량이 증가할 때 이를 감지하여 연료의 출력을 차단하므로서, 연료의 손실을 최소한으로 줄일 수 있도록 한 연료 차단장치를 제공함을 목적으로 한다.Therefore, the present invention to solve the above problems is to detect the fuel when the fuel consumption is increased due to the short circuit or crack of some of the fuel pipe of the fuel tank leaks to cut off the output of the fuel, thereby minimizing the loss of fuel It is an object of the present invention to provide a fuel shutoff device that can be reduced.

이하, 상기 목적달성을 위한 본 고안의 일 실시예를 첨부된 도 1에 의거하여 상세히 설명하면 다음과 같다.Hereinafter, an embodiment of the present invention for achieving the object will be described in detail with reference to FIG. 1.
본 고안의 연료 차단장치는 연료탱크(1)에서 배출되는 연료의 배출량을 감지하여 전기신호로 출력하는 제 1유량센서(2)와, 엔진으로 유입되는 연료의 유량을 감지하여 전기신호로 출력하는 제 2유량센서(2A)와, 상기 제 1 및 제 2유량센서(2)(2A)로부터 입력되는 데이타를 비교하여, 그 비교결과 제 1유량센서(2)에서 감지된 유량이 더 많으면 연료탱크(1)에서 배출되는 연료가 차단되도록 하기 위한 제어신호를 출력하는 제어부(3)와, 상기 연료탱크(4)의 출력단에 설치되며, 상기 제어부(3)의 제어신호에 의해 개폐되는 솔레노이드밸브(4)로 구성된다.The fuel cutoff device of the present invention detects the discharge of the fuel discharged from the fuel tank 1 and outputs it as an electric signal, and detects the flow rate of the fuel flowing into the engine and outputs it as an electric signal. Compare the data input from the second flow rate sensor 2A with the first and second flow rate sensors 2 and 2A, and if the flow rate detected by the first flow rate sensor 2 is greater, the fuel tank (1) a control unit (3) for outputting a control signal for blocking the fuel discharged from, and the solenoid valve which is installed at the output end of the fuel tank (4), and opened and closed by the control signal of the control unit (3) 4) consists of.
상기와 같이 구성된 본 고안의 일 실시예를 설명하면 다음과 같다.Referring to one embodiment of the present invention configured as described above are as follows.
먼저, 차량이 구동하여 연료탱크(1)에서 배출된 연료가 엔진으로 공급될 때, 제 1유량센서(2)는 연료탱크(1)에서 배출된 연료의 배출량을 감지하여 제어부(3)로 출력하고, 제 2유량센서(2A)는 엔진으로 유입되는 연료의 유량을 감지하여 제어부(3)로 출력한다.First, when the vehicle is driven and the fuel discharged from the fuel tank 1 is supplied to the engine, the first flow sensor 2 detects the discharge of the fuel discharged from the fuel tank 1 and outputs it to the controller 3. The second flow rate sensor 2A detects a flow rate of the fuel flowing into the engine and outputs the flow rate to the controller 3.
상기 제어부(3)는 제 1 및 제 2유량센서(2)(2A)에서 감지된 유량을 비교하고, 그 비교결과에 따라 솔레노이드밸브(4)를 개폐시킨다.The controller 3 compares the flow rates detected by the first and second flow rate sensors 2 and 2A, and opens and closes the solenoid valve 4 according to the comparison result.
즉, 제어부(3)는 연료탱크(1)에서 배출되는 유량을 감지한 제 1유량센서(2)의 감지값이 엔진으로 유입되는 연료의 유량을 감지한 제 2유량센서(2A)의 감지값보다 클 경우에 연료파이프중 일부분이 단락되었거나 크랙되어 연료가 노출되고 있다고 판단한 후 솔레노이드밸브(4)를 오프시켜 연료탱크(1)에서 연료가 배출되지 않도록 하는 것이다.That is, the controller 3 detects the flow rate of the fuel flowing into the engine by the detection value of the first flow rate sensor 2 that detects the flow rate discharged from the fuel tank 1, and the detection value of the second flow rate sensor 2A. In the case where the fuel pipe is larger, the solenoid valve 4 is turned off after determining that a part of the fuel pipe is shorted or cracked to expose the fuel so that the fuel is not discharged from the fuel tank 1.
이상에서 설명한 바와 같이 본 고안은 연료탱크의 연료파이프중 일부가 단락되거나 크랙이 발생하여 연료가 누출되어 연료소비량이 증가할 때 이를 감지하여 연료의 출력을 차단하므로서, 연로의 손실을 최소한으로 줄일 수 있도록 한 연료 차단장치이다.As described above, the present invention detects when a part of the fuel pipe of the fuel tank is short-circuited or cracked, and when fuel consumption increases, the fuel consumption is sensed to cut off the output of the fuel, thereby reducing the loss of fuel to a minimum. One fuel shutoff.
