Description
본 고안은 연료필터로 유입되는 유압과 연료필터를 거쳐서 유출되는 유압의 차이를 정확하게 측정하여 압력차이의 발생시 운전석의 신호발생부에 그 신호를 보내어 연료필터의 교환시기를 정확하게 판단할 수 있도록 안출한 차량의 연료필터 교환시기 감지장치에 관한 것이다.The present invention accurately measures the difference between the oil pressure flowing into the fuel filter and the oil pressure flowing out through the fuel filter, and sends the signal to the signal generator of the driver's seat when a pressure difference occurs, so that it is possible to accurately determine the replacement time of the fuel filter. It relates to a fuel filter replacement time detection device of a vehicle.
본 고안은 차량의 연료필터에 관한 것이다.The present invention relates to a fuel filter of a vehicle.
일반적으로 차량의 연료공급계통에서, 연료펌프를 이용하여 연료탱크의 연료를 엔진으로 압송시킬 때 연료탱크내의 불순물등이 공급되는 것을 방지하기 위하여 도 2와 같이 유입파이프(1)와 유출파이프(2) 사이에 연료필터(30)를 설치하였다.In general, in the vehicle fuel supply system, when the fuel in the fuel tank is pumped to the engine using the fuel pump, inflow pipe 1 and outlet pipe 2 as shown in FIG. The fuel filter 30 was installed between the heads.
그런데 연료의 여과효율을 높이기 위하여 연료필터(3)를 교환하여야 되는 데, 종래에는 연료필터(3)의 교환시기를 주행거리를 기준으로 하여 설정하였기 때문에 연료필터의 여과상태에 관계없이 미리 교환하거나 늦게 교환하게 되는 경우가 있다. 따라서 미리 교환하는 경우 교환시기가 누적되어 경비의 지출부담을 가지게 되고, 늦게 교환하는 경우 공연비를 유지할 수가 없어 엔진의 성능을 충분히 발휘할 수가 없는 문제점이 있었다.However, in order to increase the filtration efficiency of the fuel, the fuel filter 3 needs to be replaced. In the past, the replacement time of the fuel filter 3 was set based on the traveling distance. There is a case to be exchanged late. Therefore, when exchanging in advance, the exchange time is cumulative to have a expense burden, and when it is exchanged late, there is a problem in that the performance of the engine cannot be sufficiently exhibited because the air-fuel ratio cannot be maintained.
본 고안은 이러한 종래의 문제점을 해결하기 위하여, 연료필터로 유입되는 유압과 연료필터를 거쳐서 유출되는 유압의 차이를 정확하게 측정하여 압력차이의 발생시 운전석의 신호발생부에 그 신호를 보내어 연료필터의 교환시기를 정확하게 판단할 수 있도록 하고자 차량의 연료필터 교환시기 감지장치를 제공하는 데 그 목적이 있다.In order to solve this problem, the present invention accurately measures the difference between the oil pressure flowing into the fuel filter and the oil pressure flowing out through the fuel filter, and sends a signal to the signal generator of the driver's seat when a pressure difference occurs, thereby replacing the fuel filter. The purpose of the present invention is to provide a vehicle fuel filter replacement time detection device in order to accurately determine the timing.
본 고안은 이러하 목적을 달성하기 위한 기술적 수단으로서, 유입파이프와 유출파이프 사이에 설치되어 연료펌프에 의하여 강제적으로 압송되는 연료내의 불순물을 걸러주는 연료필터에 있어서, 유입파이프와 유출파이프에 각각 설치되어 연료의 압력을 감지하는 유입 및 유출감지센서와, 유입 및 유출감지센서를 동시에 연결하여 유입파이프와 유출파이프의 차압을 측정하는 차압측정부와, 운전석에 설치하여 차압측정부에서 측정된 차압이 입력된 기준치를 벗어나는 경우 차압측정부의 신호를 받아서 신호를 발생시키는 신호발생부로 차량의 연료필터 교환시기 감지장치를 구성한 것이 본 고안의 특징이다.The present invention is a technical means for achieving the above object, in the fuel filter is installed between the inlet pipe and the outlet pipe to filter out impurities in the fuel forcibly transported by the fuel pump, respectively installed in the inlet pipe and the outlet pipe The differential pressure measurement unit measures the differential pressure between the inflow pipe and the outflow pipe by simultaneously connecting the inflow and outflow detection sensor that detects the pressure of the fuel, the inflow and outflow detection sensor, and the differential pressure measured by the differential pressure measurement unit installed in the driver's seat.

이하 본 고안을 첨부된 실시예의 도면을 참조하여 상세히 설명하면 다음과 같다.Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.
도 1은 본 고안 차량의 연료필터 교환시기 감지장치를 나타낸 구성도로서, 부호 10은 연료펌프에 의하여 강제적으로 압송되는 연료를 안내하는 유입파이프이며, 부호 20은 유입파이프(10)에서 이송되는 연료를 에진으로 공급안내하는 유출파이프이고, 부호 30은 유입파이프(10)와 유출파이프(20) 사이에 설치하여 공급되는 연료내의 불순물을 걸러주는 연료필터이다.1 is a block diagram showing a fuel filter replacement time detection device of the present invention, reference numeral 10 is an inlet pipe for guiding the fuel forcibly transported by the fuel pump, reference numeral 20 is the fuel transported from the inlet pipe 10 Is an outlet pipe for guiding supply to the jin, and reference numeral 30 denotes a fuel filter installed between the inlet pipe 10 and the outlet pipe 20 to filter impurities in the fuel supplied.
부호 40, 50은 유입파이프(10)와 유출파이프(20)에 각각 설치되어 연료의 압력을 감지하는 유입 및 유출감지센서이다.Reference numerals 40 and 50 denote inflow and outflow detection sensors respectively installed at the inflow pipe 10 and the outflow pipe 20 to sense the pressure of the fuel.
부호 60은 유입 및 유출감지센서(40)(50)를 동시에 연결하여 유입파이프(10)와 유출파이프(20)의 차압을 측정하는 차압측정부이다.Numeral 60 is a differential pressure measuring unit for measuring the differential pressure of the inlet pipe 10 and the outlet pipe 20 by connecting the inlet and outlet sensor 40, 50 at the same time.
상기 차압측정부(60)는 유입파이프(10)와 유출파이프(20)으로 공급되는 연료압의 기준치를 미리 입력되어 있다.The differential pressure measuring unit 60 inputs a reference value of the fuel pressure supplied to the inlet pipe 10 and the outlet pipe 20 in advance.
부호 70은 운전석에 설치하여 차압측정부(60)에서 측정된 차압이 입력된 기준치를 벗어나는 경우 차압측정부(60)의 신호를 받아서 신호를 발생시키는 신호발생부이며, 그 신호발생부(70)는 발광램프 또는 발광음등으로 운전자에게 신속하게 알려줄 수 있도록 한다.Reference numeral 70 is a signal generator that is installed in the driver's seat and receives a signal from the differential pressure measurement unit 60 when the differential pressure measured by the differential pressure measurement unit 60 is out of the input reference value, and generates the signal. The driver may promptly inform the driver by emitting lamp or emitting sound.
이와 같이 구성된 본 고안은, 차량의 운전중 연료펌프에 의하여 압송되는 유입파이프(10)내의 연료압은 유입감지센서(40)가 감지하여 차압측 정부(60)로 그 신호를 보내게 되며, 유입파이프(10)로 안내되어 연료필터(30)를 통과한 연료는 불순물이 걸러진 상태에서 유출파이프(20)로 이송하게 되며, 유출파이프(20)로 이송되는 연료압은 유출감지센서(50)가 감지하여 차압측정부(60)로 그 신호를 보내게 된다.The present invention configured as described above, the fuel pressure in the inlet pipe 10 is pumped by the fuel pump during the operation of the vehicle is detected by the inflow detection sensor 40 sends a signal to the differential pressure side government 60, inflow The fuel that is guided to the pipe 10 and passed through the fuel filter 30 is transferred to the outflow pipe 20 in the state where impurities are filtered out, and the fuel pressure transferred to the outflow pipe 20 is the outflow detection sensor 50. It detects and sends the signal to the differential pressure measuring unit 60.
이때, 연료필터(30)의 정상적인 여과기능으로 유입파이프(10)와 유출파이프(20)의 연료압이 기준치범위내를 유지하게 되면 차압측정부(60)는 미리 입력된 데이타와 비교판단하여 신호발생부(70)를 작동시키지 않게 된다.At this time, if the fuel pressure of the inlet pipe 10 and the outlet pipe 20 is maintained within the standard value range by the normal filtration function of the fuel filter 30, the differential pressure measuring unit 60 compares the previously input data with a signal The generator 70 is not operated.
그러나 연료필터(30)의 여과효율저하로 연료필터(30)를 통과하는 연료량이 작아서 유입파이프(10)로 이송되는 연료압보다 유출파이프(20)로 이송되는 연료압이 작아지게 되며, 이때 유입파이프(10)와 유출파이프(20)의 연료압차이가 발생하게 되면 유입 및 유출감지센서(40)(50)가 그 압력을 감지하여 차압발생부(70)로 신호를 보내게 되고, 차압발생부(70)는 현재의 압력차와 입력된 기준치를 비교판단한 뒤 기준치를 벗어나는 경우 신호발생부(70)에 신호를 보내어 발광램프 또는 발광음등 신호가 발생되게 하므로서 운전자에게 연료필터(30)의 교환시기를 알려주게 되는 것이다.However, due to the decrease in the filtration efficiency of the fuel filter 30, the amount of fuel passing through the fuel filter 30 is small, so that the fuel pressure transferred to the outflow pipe 20 becomes smaller than the fuel pressure transferred to the inlet pipe 10, and at this time, the inflow When the fuel pressure difference between the pipe 10 and the outflow pipe 20 occurs, the inflow and outflow detection sensors 40 and 50 detect the pressure and send a signal to the differential pressure generating unit 70, and the differential pressure is generated. The unit 70 compares the current pressure difference with the input reference value and then sends a signal to the signal generator 70 to generate a light emitting lamp or a light emitting sound signal when the reference value is out of the reference value. You will be informed when the exchange.
이와 같이 본 고안은 연료필터로 유입되는 유압과 연료필터를 거쳐서 유출되는 유압의 차이를 정확하게 측정하여 압력차이의 발생시 운전석의 신호발생부에 그 신호를 보내어 연료필터의 교환시기를 정확하게 판단할 수 있도록 하므로서, 경제적인 부담감을 덜어주는 동시에 엔진의 정상적인 구동으로 엔진의 성능을 충분히 발휘할 수가 있는 효과가 있다.As such, the present invention accurately measures the difference between the oil pressure flowing into the fuel filter and the oil pressure flowing out through the fuel filter, and sends a signal to the signal generator of the driver's seat when a pressure difference occurs so that it is possible to accurately determine the replacement time of the fuel filter. As a result, it is possible to reduce the economic burden and at the same time, the engine can be fully driven by the normal driving.
