Description
본 발명은 흡배기 덕트의 압력측정장치에 관한 것으로서, 특히 흡배기 덕트의 압력 감지시 각각의 감지홀로부터 인가된 압력이 압력취합커버 내에서 평균화된 상태에서 압력감지기에 의해 감지되므로 인해 측정되는 압력정보에 대한 신뢰도를 한층 더 향상시킬 수 있을 뿐만 아니라 제품의 구조가 단순화된 제품을 제공할 수 있도록 한 흡배기 덕트의 압력측정장치에 관한 것이다.The present invention relates to a pressure measuring device of the intake and exhaust duct, and in particular, the pressure applied from each of the sensing holes when detecting the pressure of the intake and exhaust duct is detected by the pressure sensor in the averaged state in the pressure collecting cover. The present invention relates to a pressure measuring device of an intake and exhaust duct that not only improves reliability but also provides a simplified product structure.
일반적으로 차량의 엔진에서는 흡기와 배기압을 측정하기 위해 흡배기 덕트에 감지홀을 형성하고, 이 감지홀을 통해 흡배기 덕트 내의 압력을 감지하고 있다.In general, the engine of the vehicle forms a detection hole in the intake and exhaust duct to measure the intake and exhaust pressure, and senses the pressure in the intake and exhaust duct through the detection hole.
즉, 종래의 흡배기 덕트의 압력측정장치는 도 3 에 도시된 바와같이 덕트(10)의 외주연에 1개의 감지홀(11)을 관통 형성하고, 상기 감지홀(11)에 니플(12)을 돌출시키며, 상기 니플(12)에 일정길이의 튜브(13)를 결합하되,That is, the conventional pressure measuring device of the intake and exhaust duct is formed through one sensing hole 11 on the outer periphery of the duct 10, as shown in Figure 3, the nipple 12 in the sensing hole 11 Protrudes, while coupling the tube 13 of a predetermined length to the nipple 12,
상기 튜브(13)의 끝단에 압력 감지를 위한 압력감지기(14)를 설치하고, 상기 압력감지기(14)에는 압력감지기(14)에서 측정된 압력값을 표시하기 위한 압력표시부(15)가 형성되어 구성된다.The pressure sensor 14 is installed at the end of the tube 13 to detect the pressure, and the pressure sensor 14 is provided with a pressure display unit 15 for displaying the pressure value measured by the pressure sensor 14. It is composed.
이와같이 구성된 종래의 압력측정장치는 상기 덕트(10)내의 압력이 감지홀(11)을 통해 튜브(13)로 전달되고, 상기 튜브(13)를 통해 전달된 압력을 압력감지기(14)가 감지하여 압력표시부(15)를 통해 표시하게 된다.In the conventional pressure measuring device configured as described above, the pressure in the duct 10 is transmitted to the tube 13 through the sensing hole 11, and the pressure sensor 14 senses the pressure transmitted through the tube 13. The pressure is displayed through the display unit 15.
그러나, 종래의 흡배기 덕트의 압력측정장치는 덕트(10)의 일측에 형성된 한개의 감지홀(11)을 통해 흡배기 압력을 감지하는 것이기 때문에 덕트(10) 내부의 보다 정확한 압력을 측정하지 못하게되는 문제점이 발생한다.However, since the pressure measuring device of the conventional intake and exhaust duct is to detect the intake and exhaust pressure through one sensing hole 11 formed at one side of the duct 10, it becomes impossible to measure the more accurate pressure inside the duct 10. This happens.
즉, 흡배기 덕트 내부에는 엔진의 운전조건(저속, 고속 등)에 따라 심한 난류의 흐름이 존재하기 마련이고, 또한 덕트(10)가 직선이 아니라 대부분 곡선구조를 가지고 있기 때문에 덕트(10) 내부에는 항상 비정상적인 압력 파동이 존재하기 마련이며, 이러한 이유로 한곳의 감지홀(11)을 통한 압력감지는 덕트의 원주방향으로 측정 위치별 압력차이가 발생하게 되므로 그 압력감지결과에 대한 신뢰도가 그리 높지 못하게되는 것이다.That is, in the intake and exhaust ducts, there is a severe turbulent flow in accordance with the operating conditions (low speed, high speed, etc.) of the engine, and since the duct 10 mostly has a curved structure instead of a straight line, the duct 10 There is always an abnormal pressure fluctuation, and for this reason, the pressure sensing through one sensing hole 11 causes a pressure difference for each measurement position in the circumferential direction of the duct, so that the reliability of the pressure sensing result is not so high. will be.
상기와같은 문제점을 해결하기 위해 덕트의 외주연에 복수개의 감지홀을 형성하고, 각각의 감지홀에 압력감지기가 결합된 튜브를 연결한 후 각각의 압력감지기에서 감지된 정보들을 취합하여 평균을 산출하므로서 보다 정확하게 흡배기압을 측정할 수 있는 장치가 제공되고 있으나 이러한 종래기술은 많은 수의 압력감지기와 튜브를 설치해야만 하므로 그 비용이 많이 들뿐만 아니라 설치작업이 매우 번거로워지는 문제점이 발생하고 있었다.In order to solve the above problems, a plurality of sensing holes are formed on the outer circumference of the duct, and a pressure sensor is coupled to each of the sensing holes, and then the average information is calculated by collecting the information detected from each pressure sensor. As a result, a device capable of more accurately measuring intake and exhaust pressure has been provided, but such a prior art requires a large number of pressure detectors and tubes to be installed, which causes a problem that the installation work is very troublesome.
따라서, 상기 문제점을 해결하기 위한 본 발명은 흡배기 덕트의 외주연에 복수개의 감지홀을 관통 형성하고, 덕트의 외곽에 상기 감지홀들을 수용하는 밀폐된 압력취합커버를 형성하며, 상기 압력취합커버의 일측에 압력감지기와 연결된 상태의 튜브를 연통되게 결합하므로서, 흡배기 덕트의 압력 감지시 각각의 감지홀로부터 인가된 압력이 압력취합커버 내에서 평균화된 상태에서 압력감지기에 의해 감지되므로 인해 측정되는 압력정보에 대한 신뢰도를 한층 더 향상시킬 수 있을 뿐만 아니라 제품의 구조가 단순화된 제품을 제공할 수 있도록 한 흡배기 덕트의 압력측정장치를 제공함을 목적으로 한다.Therefore, the present invention for solving the above problems is formed through the plurality of detection holes through the outer periphery of the intake and exhaust duct, and form a sealed pressure collection cover for receiving the detection holes in the outer duct, the pressure of the cover By connecting the tube in the state connected to the pressure sensor on one side in communication, the pressure information measured by the pressure sensor in the average state in the pressure collection cover when the pressure applied from each sensing hole in the pressure detection of the intake and exhaust duct It is an object of the present invention to provide a pressure measuring device for an intake and exhaust duct that can further improve the reliability of the product and to provide a simplified product structure.

Be sure to
상기 압력취합커버(3)의 일측에는 튜브(5)의 결합을 위한 니플(4)을 형성하고, 상기 니플(4)에 일정길이의 튜브(5)를 연결한다.One side of the pressure collection cover (3) forms a nipple (4) for coupling of the tube (5), and connects the tube (5) of a predetermined length to the nipple (4).
