본 발명은 배기가스의 온도에 따라 촉매담체의 위치가 가변되는 촉매컨버터에 관한 것으로서, 보다 상세하게는 피니언 및 스텝모터에 의해서 배기가스의 온도가 일정 수준 이하이면 필터담체가 하우징의 전방으로 이동되고, 배기가스의 온도가 일정 수준 이상이면 필터담체가 하우징의 후방으로 이동되도록 구성되는 배기가스의 온도에 따라 촉매담체의 위치가 가변되는 촉매컨버터에 관한 것이다.The present invention relates to a catalytic converter in which the position of the catalyst carrier is variable according to the temperature of the exhaust gas. In addition, when the temperature of the exhaust gas is above a certain level, the filter carrier is related to a catalytic converter in which the position of the catalyst carrier is changed according to the temperature of the exhaust gas configured to be moved to the rear of the housing.

엔진에서 배기 매니폴드를 통해 배출되는 배기가스는 배기 파이프를 거쳐 촉매컨버터(Catalytic converter)로 도입되어 정화되고, 머플러를 통과하면서 소음이 감쇄된 후 배기파이프를 통해 대기 중으로 방출된다. 상기한 촉매컨버터는 매연여과장치(DTF, Diesel Particulate Filter)의 일종으로 배출가스에 포함되어 있는 오염물질을 처리하는 역할을 하는 것이다.Exhaust gas discharged from the engine through the exhaust manifold is introduced into the catalytic converter through the exhaust pipe to be purified, and the noise is attenuated while passing through the muffler and then discharged into the atmosphere through the exhaust pipe. The catalytic converter is a kind of a diesel particulate filter (DTF) that serves to process contaminants contained in the exhaust gas.

도 6은 일반적인 촉매컨버터의 단면도이고, 도 7은 도 6의 B-B선 단면도이다. 도면에서와 같이 촉매컨버터(10)의 하우징(11) 내측에 촉매담체(13)가 형성되는데, 상기 촉매담체(13)와 하우징(11) 사이에는 매트(12)가 개재되어 있다. 상기 매트(12)는 배기가스 열에 의해 뜨거워진 필터담체의 열이 하우징(11)으로 전달되는 것을 방지하고, 소음을 흡수하는 역할을 하는 것이다. 특히, 상기한 촉매담체 (13)의 단면은 다수의 벽과 채널로 이루어지며, 각 채널로 유입된 배기가스는 벽을 통해 이웃하는 채널로 이동되는 과정에서 입자상 물질이 채널의 벽에 포집되는 것이다.6 is a cross-sectional view of a general catalytic converter, and FIG. 7 is a cross-sectional view taken along line B-B of FIG. 6. As shown in the figure, a catalyst carrier 13 is formed inside the housing 11 of the catalytic converter 10, and a mat 12 is interposed between the catalyst carrier 13 and the housing 11. The mat 12 prevents heat of the filter carrier heated by the exhaust gas heat from being transferred to the housing 11, and serves to absorb noise. In particular, the cross section of the catalyst carrier 13 is composed of a plurality of walls and channels, and the exhaust gas introduced into each channel is collected in the wall of the channel in the process of moving to the adjacent channel through the wall. .

그런데 상기와 같은 종래의 촉매컨버터는 배기가스의 온도변화와는 상관없이 촉매담체와 하우징이 일체형으로 고정형성되므로서, 배기가스의 온도와 무관하게촉매담체가 작용되어 배기가스를 산화 및 환원시키는 정화효율이 저하되는 문제점이 있었다.However, in the conventional catalytic converter, the catalyst carrier and the housing are fixedly formed irrespective of the temperature change of the exhaust gas so that the catalyst carrier acts independently of the temperature of the exhaust gas to oxidize and reduce the exhaust gas. There was a problem that the efficiency is lowered.

따라서 본 발명은 상기와 같은 문제점을 해결하기 위해서 안출된 것으로서, 피니언 및 스텝모터에 의해서 배기가스의 온도가 일정 수준 이하이면 필터담체가 하우징의 전방으로 이동되고, 배기가스의 온도가 일정 수준 이상이면 필터담체가 하우징의 후방으로 이동되도록 구성되는 배기가스의 온도에 따라 촉매담체의 위치가 가변되는 촉매컨버터를 제공하는 데 목적이 있다.Accordingly, the present invention has been made to solve the above problems, the filter carrier is moved to the front of the housing when the temperature of the exhaust gas is a certain level or less by the pinion and the step motor, if the temperature of the exhaust gas is above a certain level An object of the present invention is to provide a catalytic converter in which the position of the catalyst carrier is changed according to the temperature of the exhaust gas configured to move the filter carrier to the rear of the housing.

This is a flowchart of the catalytic converter.

도면 중에 표시되는 도면부호는 20은 본 발명에 의해 형성되는 촉매컨버터를 지시하는 것으로서, 본 발명에 의한 촉매컨버터(20)는 하우징(21)의 내부에 수용되는 촉매담체(30)가 전후방향으로 이동될 수 있도록 형성된다.In the drawings, reference numeral 20 denotes a catalytic converter formed by the present invention, and the catalytic converter 20 according to the present invention includes a catalyst carrier 30 accommodated in the housing 21 in the front-rear direction. It is formed to be movable.

상기한 하우징(21)은 그 측단면 형상이 타원형상이고 길이방향으로 길게 형성되어 그 내부에 소정의 챔버(22)가 마련되며, 상기한 챔버(22) 내부에는 촉매담체(30)가 전후로 이동될 수 있도록 수용된다. 그리고 촉매담체(30)와 일체로 형성되는 랙(40)이 이동될 수 있도록 상기 하우징(21)의 일측에는 가이드 레일(23)이 길이방향으로 형성되는데, 본 발명을 설명하기 위한 실시예에서는 상기한 가이드 레일(23)이 하우징(21)의 하측면에 형성된다.The housing 21 has an elliptical shape in its side cross-section and is elongated in the longitudinal direction, and a predetermined chamber 22 is provided therein, and the catalyst carrier 30 is moved back and forth within the chamber 22. Are accepted to help. In addition, the guide rail 23 is formed at one side of the housing 21 in the longitudinal direction so that the rack 40 integrally formed with the catalyst carrier 30 can be moved. One guide rail 23 is formed on the lower side of the housing 21.

그리고 배기가스 중에 포함된 입자상 물질을 정화하기 위한 촉매담체(30)의 일측면에는 상기한 가이드 레일(23)에 위치될 랙(40)이 일체로 형성되는데, 상기한 촉매담체(30)를 챔버(22) 내부에 수용시켰을 경우 상기 랙(40)이 하우징(21)의 외측면으로 돌출되도록 형성되는 것이다.The rack 40 to be positioned on the guide rail 23 is integrally formed on one side of the catalyst carrier 30 for purifying particulate matter contained in the exhaust gas, and the catalyst carrier 30 is formed in the chamber. (22) When accommodated inside the rack 40 is formed to protrude to the outer surface of the housing (21).

한편, 상기한 랙(40)과 맞물리는 피니언(50)은 하우징(21)의 외부측에 형성되고, 상기 피니언(50)의 중심축은 제어부(60)의 제어에 의해 작동되는 스텝모터(51)에 연결된다.On the other hand, the pinion 50 engaged with the rack 40 is formed on the outer side of the housing 21, the central axis of the pinion 50 is operated by the control of the control unit 60 step motor 51 Is connected to.

또한, 상기한 챔버(22)에는 유입되는 배기가스의 온도를 측정하기 위한 온도센서(61)가 형성되는데, 상기 온도센서(61)에서 측정되는 측정온도값은 제어부(60)에 전달되도록 설정된다. 그리고 제어부(60)는 온도센서(61)에서 측정된 측정온도값과 기설정된 온도범위를 비교한 다음, 측정온도값이 설정범위에 포함되면 현재의 촉매담체(30)의 위치가 유지되도록 설정되고, 측정온도값이 설정범위의 최고값보다 높으면 촉매담체(30)가 후진되도록 설정되고, 측정온도값이 설정범위의 최저값보다 낮으면 촉매담체(30)가 전진되도록 설정된다.In addition, the chamber 22 is formed with a temperature sensor 61 for measuring the temperature of the incoming exhaust gas, the measured temperature value measured by the temperature sensor 61 is set to be transmitted to the controller 60. . Then, the controller 60 compares the measured temperature value measured by the temperature sensor 61 with a preset temperature range, and when the measured temperature value is included in the set range, the current position of the catalyst carrier 30 is maintained. When the measured temperature value is higher than the highest value of the set range, the catalyst carrier 30 is set backward. When the measured temperature value is lower than the lowest value of the set range, the catalyst carrier 30 is set to advance.

특히, 상기한 설정온도의 최저값은 190~210℃로, 최고값은 340~360℃로 설정되는 것이 바람직하다.In particular, it is preferable that the minimum value of the above-mentioned set temperature is set to 190 to 210 ° C, and the maximum value is set to 340 to 360 ° C.

또한, 상기한 촉매담체(30)는 엔진의 시동이 정지되었을 때나, 혹은 시동 초기시에 기본의 위치로 이동될 수 있도록 설정되는 것이 바람직하다.In addition, the catalyst carrier 30 is preferably set so that the catalyst carrier 30 can be moved to a basic position when the engine is stopped or at the start of the engine.

이상과 같이 형성되는 촉매컨버터의 작동상태를 도면과 함께 설명하면 다음과 같다.The operating state of the catalytic converter formed as above will be described with reference to the drawings.

상기와 같이 배기가스의 온도에 따라 촉매담체(30)의 위치가 가변되도록 설정된 촉매컨버터(20)가 장착된 엔진이 시동되어 운전되어지면, 연소실에서 발생된 연소가스는 배기계를 통해 상기한 촉매컨버터(20)의 챔버(22)로 유입되어진다.As described above, when the engine equipped with the catalytic converter 20 set such that the position of the catalyst carrier 30 is changed according to the temperature of the exhaust gas is started and operated, the combustion gas generated in the combustion chamber is transferred to the catalytic converter through the exhaust system. Inflow into the chamber 22 of the (20).

촉매컨버터(20)의 챔버(22)로 유입되는 배기가스의 온도는 챔버(22)에 내부에 장착된 온도센서(61)에 의해서 배기가스온도가 측정되고, 측정온도값은 제어부(60)에서 기설정된 측정범위와 비교되어진다.The temperature of the exhaust gas flowing into the chamber 22 of the catalytic converter 20 is measured by the temperature sensor 61 mounted inside the chamber 22, and the measured temperature value is measured by the controller 60. It is compared with the preset measurement range.

그리고 측정온도값이 설정범위 내에 포함되면 상기한 촉매담체(30)는 현재의 기본위치를 유지하게 되고, 측정온도값이 설정범위의 최고값(MAX)보다 크면 촉매담체(30)가 후퇴되도록 스텝모터(51)가 회전되고, 측정온도값이 설정범위의 최저값(MIN)보다 작으면 촉매담체(30)가 전진되도록 스텝모터(51)가 회전된다.When the measured temperature value is within the set range, the catalyst carrier 30 maintains the current basic position. When the measured temperature value is greater than the maximum value MAX of the set range, the catalyst carrier 30 is retracted. When the motor 51 is rotated and the measured temperature value is smaller than the minimum value MIN of the set range, the step motor 51 is rotated so that the catalyst carrier 30 is advanced.

따라서 스텝모터(51)의 회전방향에 따라서 피니언(50)이 회전되고, 피니언(50)과 기어가 맞물린 랙(40)의 움직여 촉매담체(30)를 이동시키게 된다. 그래서 상기한 촉매담체(30)는 제어부(60)의 제어에 의해 온도센서(61)에서 측정되는 측정온도값에 따라서 기설정된 스트로크 범위 내에서 전후로 이동되어진다.Accordingly, the pinion 50 is rotated in accordance with the rotational direction of the step motor 51, and the catalyst carrier 30 is moved by moving the rack 40 meshed with the pinion 50. Thus, the catalyst carrier 30 is moved back and forth within the preset stroke range according to the measured temperature value measured by the temperature sensor 61 under the control of the controller 60.

그리고 차량의 운전이 다 끝나고 엔진의 시동이 멈춰지게 되면 상기한 촉매담체(30)는 기본위치로 이동되어진다.When the driving of the vehicle is finished and the engine is stopped, the catalyst carrier 30 is moved to the basic position.

즉, 배기가스의 온도가 고온일 경우에는 상기한 촉매담체(30)가 후방으로 이동되어 배기가스에 포함된 입자상물질을 포집하게 되고, 배기가스의 온도가 저온일 경우에는 촉매담체(30)가 전방으로 이동되어 배기가스에 포함된 입자상물질을 포집하게 된다.That is, when the temperature of the exhaust gas is a high temperature, the catalyst carrier 30 is moved backward to collect particulate matter contained in the exhaust gas. When the temperature of the exhaust gas is low temperature, the catalyst carrier 30 is It is moved to the front to collect particulate matter contained in the exhaust gas.

이상과 같이 구성되는 촉매컨버터는 최적의 정화효율이 유지될 수 있도록 촉매담체의 위치가 배기가스의 온도에 따라서 이동되므로서 배기가스정화효율이 상승되며, 보다 강화되는 국내 및 국외의 배기가스 규제치를 만족시킬 수 있는 커다란장점이 있는 것이다.The catalytic converter configured as described above increases the exhaust gas purification efficiency by moving the position of the catalyst carrier according to the temperature of the exhaust gas so that the optimum purification efficiency can be maintained. There is a big advantage to satisfy.
