본 고안은 자동차 배기가스 성분 및 온도측정 겸용 어뎁터에 관한 것으로, 특히 배기가스 성분분석기용 커넥터를 포함한 쓰리웨이(3-WAY) 커넥터식으로 어뎁터를 형성하여 배기가스 온도뿐만 아니라 동시에 배기가스 성분도 측정할 수 있도록 한 자동차 배기가스 성분 및 온도측정 겸용 어뎁터에 관한 것이다.The present invention relates to a vehicle exhaust gas component and a temperature measuring adapter, in particular to form an adapter in a three-way (3-WAY) connector type including a connector for the exhaust gas component analyzer to measure not only the exhaust gas temperature but also the exhaust gas component at the same time. The present invention relates to a vehicle exhaust gas component and a temperature measuring adapter.

[고안이속하는기술분야및그분야의종래기술][Technical field to which the draft belongs and its prior art]

일반적으로 자동차는 가솔린(휘발유), 경유 및 윤활유가 혼합된 혼합유 등의 각종 연료를 에너지원으로 사용하는데, 상기 연료를 엔진의 실린더내로 유입시켜 점화플러그에 의해 점화시켜서 크랭크축을 회전시키는 흡입, 압축, 팽창, 배기행정을 통해 상기 크랭크축의 플라이휠을 회전시키므로써 동력을 바퀴에 전달하게 된다.In general, automobiles use various fuels, such as gasoline (petrol), gasoline, and mixed oils mixed with lubricating oil, as energy sources.The fuel is introduced into a cylinder of the engine and ignited by an ignition plug to rotate the crankshaft. Power is transmitted to the wheels by rotating the flywheel of the crankshaft through expansion, exhaust stroke.

상기와 같이 연료를 공기와 혼합시켜 실린더내로 유입시키는 장치로 초기에 기계제어식 기화기를 사용하였는데 이 방식은 배기가스의 다량배출로 환경오염을 유발시키는 문제가 있어 현재는 거의 사용되지 않고 대신에 배기가스를 자동차의 속도에 따라 적절하게 제어하는 전자제어식 연료분사장치가 사용되고 있다.As a device for mixing fuel with air and introducing it into a cylinder, a mechanically controlled vaporizer was used initially. This method causes environmental pollution due to a large amount of exhaust gas. Electronically controlled fuel injection device is used to properly control the fuel consumption according to the speed of the vehicle.

환경오염으로 인한 규제에 대응하기 위한 상기와 같은 배기가스의 억제와 더불어 자동차의 성능향상을 위한 연비향상이 자동차의 공해감소와 에너지절약을 위해서 현재 자동차 기술에 있어서 중요한 문제이기 때문에 배기가스와 연비측정을 위해 자동차 생산업체들은 샤시 동력계와 배기가스 분석기를 사용하여 연비와 배기가스를 측정하고 있다.In addition to the above suppression of exhaust gas to cope with regulations due to environmental pollution, fuel efficiency improvement for automobile performance improvement is an important problem in automobile technology for reducing pollution and energy saving of automobiles. Automotive manufacturers are using chassis dynamometers and exhaust analyzers to measure fuel economy and emissions.

상기 샤시 동력계는 자동차가 실제도로를 주행할 때와 같은 여건을 시험실에 재현하여 연비를 산출해내는 시스템이고, 배기가스 분석기는 시험차량의 배기관으로 부터 나오는 일산화탄소, 탄화수소, 질소산화물등 유해물질을 측정하는데 사용된다.The chassis dynamometer is a system that calculates fuel efficiency by reproducing the same conditions as when the vehicle is driving on an actual road, and the exhaust gas analyzer measures harmful substances such as carbon monoxide, hydrocarbons, and nitrogen oxides from the exhaust pipe of the test vehicle. It is used to

특히, 각 나라마다 배기가스의 규제기준이 다르고 사용연료도 달라 수출을 하려면 해당지역 또는 해당국가의 해당연료에 따른 기준에 맞추어야 한다.In particular, different countries have different regulatory standards for exhaust gas and use different fuels.

실제 우리나라의 경우도 새로 개발된 차뿐만 아니라 수입차도 배기가스 검사를 통하여 규제기준에 통과하여야 국내에서 판매가 가능한 실정이다.In fact, in Korea, imported cars as well as newly developed cars must pass the regulatory standards through the exhaust gas inspection to be sold in Korea.

이러한 배기가스 규제에 대응하여 메이커에서는 배기가스의 성분과 배기가스의 온도를 측정하기 위하여 어뎁터를 사용하는데, 배기가스 온도측정용 어뎁터의 경우 도 1의 (가)에 나타낸 바와같이 배기다기관용 커넥터와 배기가스 온도측정기용 커넥터를 가진 투웨이(2-WAY) 커넥터식의 어뎁터()를 사용하였다.In response to these regulations, manufacturers use adapters to measure the composition of exhaust gases and the temperature of exhaust gases.In the case of the exhaust gas temperature measurement adapter, as shown in FIG. A 2-way connector type adapter () having a connector for a gas temperature measuring instrument was used.

즉, 상기 투웨이(2-WAY) 커넥터식의 어뎁터(1)는 그 일측에 배기다기관(2)에 연결되는 커넥터(1b)를 가진 파이프(1a)가 설치되어 있고, 타측에 배기가스 온도측정기에 연결되는 커넥터(1c)가 설치되어 있으며, 상기 파이프(1a)의 내경은 상기 배기가스 온도측정기의 센싱봉(3) 외경과 일치되게 형성되어 이루어진 것이다.That is, the 2-way connector type adapter 1 has a pipe 1a having a connector 1b connected to the exhaust manifold 2 on one side thereof, and an exhaust gas temperature measuring instrument on the other side thereof. The connector 1c to be connected is installed, and the inner diameter of the pipe 1a is formed to match the outer diameter of the sensing rod 3 of the exhaust gas temperature measuring instrument.

이와같은 어뎁터(1)의 파이프(1a)를 그 커넥터(1b)에 의해 배기다기관(2)에 연결하고, 어뎁터(1)내로 센싱봉(3)을 삽입하여 도 2에 나타낸 바와같이 상기 파이프(1a)에 배기가스가 유입되지 않게 센싱봉(3)이 꽉 끼워서 상기 배기다기관(2)내로 돌출설치하여 엔진에서 배기다기관(2)으로 배출되는 배기가스의 온도를 상기 센싱봉(3)에 의해 감지하여 배기가스의 온도를 측정하였다.The pipe 1a of the adapter 1 is connected to the exhaust manifold 2 by the connector 1b, and the sensing rod 3 is inserted into the adapter 1, and as shown in FIG. The sensing rod 3 is tightly inserted to protrude into the exhaust manifold 2 so that the exhaust gas does not flow into 1a) and the temperature of the exhaust gas discharged from the engine to the exhaust manifold 2 is determined by the sensing rod 3. The temperature of the exhaust gas was measured by sensing.

상기 센싱봉(3)은 두 종류의 금속을 붙여서 만든 열전쌍(thermo couple)으로 된 것이다.The sensing rod 3 is a thermo couple made by attaching two kinds of metals.

상기와 같이 배기가스 온도측정용 어뎁터(1)를 이용하여 배기가스 온도측정기의 센싱봉(3)에 의해 배기가스 온도를 측정하였고, 배기가스 성분은 상기 배기가스 온도측정용 어뎁터(1)와는 다른 별도의 배기가스 성분측정용 어뎁터에 의해 측정하였다.The exhaust gas temperature was measured by the sensing rod 3 of the exhaust gas temperature measuring instrument using the exhaust gas temperature measuring adapter 1 as described above, and the exhaust gas component is different from the exhaust gas temperature measuring adapter 1. It measured by the other adapter for exhaust gas component measurement.

이렇게 종래 별개의 배기가스 성분 및 온도측정용 어뎁터를 사용하여 배기가스 성분 및 온도를 측정하다 보니 배기다기관에 각 어뎁터를 설치해야 하는 번거로운 작업이 필요하며, 이에 따라 배기가스 성분 및 온도 측정시간이 오래 걸리고, 또한 배기가스 성분 및 온도를 각각 별도로 분석측정하기 때문에 분석측정의 신뢰성이 떨어지는 문제점이 있었다.As such, exhaust gas components and temperature are measured using a separate exhaust gas component and a temperature measuring adapter, which requires cumbersome work to install each adapter in the exhaust manifold, so that the exhaust gas component and temperature measurement time is long. There is also a problem that the reliability of the analytical measurement is poor because it is separately measured and measured separately the exhaust gas component and temperature.

[고안이이루고자하는기술적과제][Technical Challenges to be Done]

본 고안은 상기 문제점을 고려하여 배기가스 성분 및 배기가스 온도를 동시에 측정할 수 있도록 배기가스 성분분석기용 커넥터를 포함한 쓰리웨이(3-WAY) 커넥터식으로 어뎁터를 형성하여 배기가스 성분 및 온도 측정시간의 단축, 작업성향상 및 측정신뢰성을 향상시키고자 한 자동차 배기가스 성분 및 온도측정 겸용 어뎁터를 제공함에 그 목적이 있는 것이다.The present invention forms an adapter in a 3-way connector type including an exhaust gas component analyzer connector so that the exhaust gas component and exhaust gas temperature can be simultaneously measured in consideration of the above problems. It is an object of the present invention to provide a vehicle exhaust gas component and temperature adapter for the purpose of shortening, improving workability and measuring reliability.

이와같은 본 고안의 목적은 배기가스 성분분석기에 연결되는 커넥터를 형성하고, 배기다기관에 연결되는 커넥터를 가진 파이프 내경을 배기가스 온도측정기용 커넥터에 연결되는 배기가스 온도측정기의 센싱봉 외경보다 크게 형성하여 배기가스 성분 및 온도측정 겸용 어뎁터를 구성하므로써 달성되는 것이다.The object of the present invention is to form a connector connected to the exhaust gas analyzer, and to form a pipe inner diameter having a connector connected to the exhaust manifold larger than an outer diameter of the sensing rod of the exhaust gas temperature measuring instrument connected to the connector for the exhaust gas temperature measuring instrument. This is achieved by configuring an exhaust gas component and a temperature measuring adapter.

상기한 센싱봉의 외경과 파이프의 내경차이로 인해 형성된 틈새로는 배기가스가 유입되어 배기가스 성분분석기로 흘러 들어가게 되어 배기가스의 성분을 분석할 수 있고, 상기 센싱봉으로는 배기가스의 온도를 측정할 수 있게 되는 것이다.The gap formed by the difference between the outer diameter of the sensing rod and the inner diameter of the pipe allows the exhaust gas to flow into the exhaust gas component analyzer to analyze the components of the exhaust gas, and the sensing rod measures the temperature of the exhaust gas. You can do it.

[고안의구성및작용][Composition and Action of Design]

이하 본 고안의 기술구성과 작용 및 효과를 첨부한 바람직한 실시예로 나타낸 도면에 의거하여 상세하게 기술하면 다음과 같다.Hereinafter, the technical configuration, operation, and effect of the present invention will be described in detail with reference to the accompanying drawings.

이에 나타낸 바와같이 본 고안은 배기가스 성분분석기에 연결되는 커넥터(14)를 형성하고, 배기다기관(2)에 연결되는 커넥터(12)를 가진 일측 파이프(11)의 내경을 타측의 배기가스 온도측정기용 커넥터(13)에 연결되는 배기가스 온도측정기의 센싱봉(3) 외경보다 크게 형성하여 쓰리웨이(3-WAY) 커넥터식으로 배기가스 성분 및 온도측정 겸용 어뎁터(10)를 구성한 것이다.As shown here, the present invention forms a connector 14 connected to the exhaust gas component analyzer, and measures the inside diameter of one pipe 11 having the connector 12 connected to the exhaust manifold 2 on the other side of the exhaust gas temperature measuring instrument. It is formed larger than the outer diameter of the sensing rod (3) of the exhaust gas temperature measuring instrument connected to the connector 13 for the three-way (3-WAY) connector type to configure the exhaust gas component and the temperature measuring adapter (10).

상기 센싱봉 외경과 파이프 내경의 차이로 인해 센싱봉(3)을 파이프(11)에 삽설하면 파이프(11)와 센싱봉(3) 사이에는 틈새(11a)가 형성된다.When the sensing rod 3 is inserted into the pipe 11 due to the difference between the outer diameter of the sensing rod and the inner diameter of the pipe, a gap 11a is formed between the pipe 11 and the sensing rod 3.

즉, 본 고안은 일측에 배기다기관에 연결되는 커넥터를 가진 파이프가 설치되어 있고, 타측에 배기가스 온도측정기에 연결되는 커넥터가 설치되어 있는 어뎁터에 있어서, 상기 어뎁터에 배기가스 성분분석기에 연결되는 커넥터(14)를 형성하고, 상기 파이프의 내경은 상기 배기가스 온도측정기의 센싱봉(3) 외경보다 크게 형성하여 T자형상으로 배기가스 성분 및 온도측정 겸용 어뎁터(10)를 구성한 것이다.That is, in the present invention, an adapter having a pipe connected to an exhaust manifold on one side, and a connector connected to an exhaust gas temperature meter on the other side, the connector connected to the exhaust gas component analyzer on the adapter (14), and the inner diameter of the pipe is larger than the outer diameter of the sensing rod (3) of the exhaust gas temperature measuring instrument to form the exhaust gas component and the temperature measuring adapter (10) in a T-shape.

이와같이 본 고안의 배기가스 성분 및 온도측정 겸용 어뎁터(10)를 형성하여 도 2의 (나)에 나타낸 것과 같이 상기 어뎁터(10)의 파이프(11)의 커넥터(12)를 배기다기관(2)에 연결하고, 상기 어뎁터(10)의 배기가스 온도측정기용 커넥터(13)에 상기 어뎁터(10)내로 배기가스 온도측정기의 센싱봉(3)을 삽설하여 상기 파이프(11)를 통해 상기 배기다기관(2)내로 상기 센싱봉(3)이 돌출되게 배기가스 온도측정기를 연결하며, 상기 어뎁터(10)의 배기가스 성분분석기용 커넥터(14)에 배기가스 성분분석기를 연결하여 배기가스 성분분석과 온도측정을 하게 되는 것이다.Thus, the exhaust gas component and the temperature measuring adapter 10 of the present invention are formed, and the connector 12 of the pipe 11 of the adapter 10 is connected to the exhaust manifold 2 as shown in FIG. And a sensing rod 3 of the exhaust gas temperature measuring instrument inserted into the adapter 10 to the exhaust gas temperature measuring connector 13 of the adapter 10 and the exhaust manifold 2 through the pipe 11. Connect the exhaust gas temperature measuring instrument so that the sensing rod 3 protrudes, and connect the exhaust gas component analyzer to the connector 14 for the exhaust gas component analyzer of the adapter 10 to perform exhaust gas component analysis and temperature measurement. Will be done.

이렇게 배기가스 성분 및 온도측정 겸용 어뎁터(10)를 연결설치하게 되면, 센싱봉(3)과 파이프(11) 사이의 틈새(11a)를 통하여 배기다기관(2)의 배기가스가 유입되어 어뎁터(10)를 통해서 배기가스 성분분석기로 흘러들어가게 된다.When the exhaust gas component and the temperature measuring adapter 10 are connected to each other, the exhaust gas of the exhaust manifold 2 flows in through the gap 11a between the sensing rod 3 and the pipe 11 so that the adapter 10 ) Into the exhaust gas analyzer.

따라서 상기 배기가스 성분분석기에 의해 배기가스의 성분을 분석할 수 있음과 동시에 상기 배기다기관(2)내로 돌출되어있는 센싱봉(3)에 의해서는 배기가스의 온도를 측정할 수 있게 되는 것이다.Accordingly, the components of the exhaust gas can be analyzed by the exhaust gas component analyzer, and the temperature of the exhaust gas can be measured by the sensing rod 3 protruding into the exhaust manifold 2.
