Description

통합 언더플로어 촉매컨버터 조립체{Integrated underfloor catalytic converter assembly}Integrated underfloor catalytic converter assembly

본 발명은 통합형 언더플로어 촉매컨버터 조립체에 관한 것이다. 보다 상세하게는 종래의 웜업 촉매컨버터와 언더플로어 촉매컨버터를 통합하여 하나의 캐닝 안에 두 개의 촉매가 있는 통합형 언더플로어 촉매컨버터 조립체에 관한 것이다.The present invention relates to an integrated underfloor catalytic converter assembly. More particularly, the present invention relates to an integrated underfloor catalytic converter assembly having two catalysts in one canning by integrating a conventional warm-up catalytic converter and an underfloor catalytic converter.

일반적으로 내연기관은 실린더블록의 연소실내에서의 연소된 연소가스가 실린더헤드와 배기매니폴드 및 배기파이프를 거쳐 대기로 배출되는 배기시스템이 구비되고, 이때, 엔진으로부터 배기되는 고온ㅇ고속ㅇ고압의 배기가스에 의한 대기와의 압력차에 따른 소음을 저감하도록 소음기를 장착하여 배기가스의 온도와 압력을 낮추어 배기소음을 저하시키고 있다.In general, an internal combustion engine is provided with an exhaust system through which the combusted combustion gas in the combustion chamber of a cylinder block is discharged to the atmosphere through a cylinder head, an exhaust manifold, and an exhaust pipe. In order to reduce noise caused by the pressure difference with the atmosphere due to the exhaust gas, a silencer is mounted to reduce the exhaust noise by lowering the temperature and pressure of the exhaust gas.

또한, 배기가스 속에는 CO, HC 및 NOx 등의 유해가스 들이 다량으로 포함되어 있어 이를 그대로 대기로 방출하게 되면 환경을 오염시키고 호흡기 질환을 유발하는 등의 여러 문제를 가져오게 되므로 이들 유해가스를 무해한 CO2, H2O 및 N2로 산화, 환원시켜 배출하기 위한 촉매컨버터가 배기파이프 상에 구비된다.In addition, the exhaust gas contains a large amount of harmful gases such as CO, HC, and NOx, and if released to the atmosphere as it is, it causes various problems such as polluting the environment and causing respiratory diseases. A catalytic converter is provided on the exhaust pipe for oxidizing, reducing and discharging with H 2 O and N 2.

도 1은 종래의 촉매 컨버터로 도 1의 (a)는 웜업 촉매컨버터를 도시한 그림이고, 도 1의 (b)는 언더플로어 촉매컨버터를 도시한 그림이다.Figure 1 is a conventional catalytic converter Figure 1 (a) is a diagram showing a warm-up catalytic converter, Figure 1 (b) is an illustration showing an underfloor catalytic converter.

웜업 촉매컨버터(WCC: Warm-up Catalytic Converter, 10)는 엔진의 바로 뒤에 설치되고, 엔진의 웜업 이전에 배출되는 배기가스를 주로 정화하고, 언더플로어 촉매컨버터(UCC: Under-floor Catalytic Converter, 20)는 차량의 아래에 설치되고, 엔진의 웜업 이후에 배출되는 배기가스를 주로 정화한다.Warm-up Catalytic Converter (WCC) (10) is installed directly behind the engine, mainly purifies the exhaust gas prior to warm-up of the engine, and under-floor Catalytic Converter (UCC) 20 ) Is installed under the vehicle and mainly purifies the exhaust gas emitted after the warm-up of the engine.

유로4는 유럽연합(EU)이 경유승용차에 적용하는 배기가스 허용기준치로 종래는 상기 WCC(10)와 UCC(20)로 조합된 촉매컨버터를 이용하여 상기 유로4에서 정하는 에미션(Emission) 규제보다 배출되는 상기 배기가스내의 오염물질의 양이 적어지도록 촉매컨버터를 제조하였다.Euro 4 is an emission limit value applied by the European Union to diesel passenger vehicles. Conventionally, emission regulation prescribed in Euro 4 is performed by using a catalytic converter combined with the WCC 10 and the UCC 20. A catalytic converter was manufactured so that the amount of pollutants in the exhaust gas discharged more was reduced.

그러나 이러한 촉매컨버터는 상기 WCC(10)와 UCC(20)의 촉매의 양이 증가되어도 정화된 오염물질의 양이 줄지 않고, 오히려 상기 오염물질의 양이 증가하는 현상을 보여 개발목표치가 만족되지 않게 되었다. 그리고 촉매의 양이 증가됨에 따라 촉매컨버터의 제조비용이 증가하는 현상이 나타난다.However, such a catalytic converter does not reduce the amount of purified pollutants even if the amount of the catalyst of the WCC 10 and the UCC 20 is increased, but rather increases the amount of the pollutants so that the development target is not satisfied. It became. As the amount of the catalyst increases, the production cost of the catalytic converter increases.

따라서 본 발명은 이러한 문제점을 해결하기 위해 발명한 것으로서, 유로4에 규정된 배기가스의 오염물질의 배출량보다 더욱 낮게 정한 목표치에 만족하고, 촉 매컨버터의 제조비용을 줄일 수 있도록 촉매컨버터의 형상이 최적화된 촉매컨버터를 제공하는데 그 목적이 있다.Therefore, the present invention has been invented to solve such a problem, and the shape of the catalytic converter can be reduced so as to satisfy the target value set lower than the emission of pollutants in the exhaust gas specified in the Euro 4, and to reduce the manufacturing cost of the catalytic converter. The purpose is to provide an optimized catalytic converter.

이상에서 설명한 바와 같이 본 발명에 의하면, 하나로 구성된 촉매컨버터 조립체에서 오염물질의 양에 따라 제1 촉매컨버터와 제2 촉매컨버터에서 정화되는 비율이 조절될 수 있어 최적의 촉매정화성능을 발휘할 수 있다는 효과가 있다. 또한 본 발명의 촉매컨버터는 유동가이드가 포함되어 있으므로 차량에 설치될 때 상기 유동가이드의 길이를 조절하여 상기 차량의 종류에 따라서 유기적으로 설치할 수 있다는 효과가 있다.As described above, according to the present invention, the ratio of the purification of the first catalytic converter and the second catalytic converter can be controlled according to the amount of contaminants in the single catalytic converter assembly, thereby achieving the optimum catalytic purification performance. There is. In addition, since the catalytic converter of the present invention includes a flow guide, it can be installed organically according to the type of the vehicle by adjusting the length of the flow guide when installed in the vehicle.

또한, 정화효율이 증가되어 상기 촉매컨버터 조립체에서 정화되는 오염물질의 양이 증가되어 더욱 정화된 배기가스가 배출된다는 효과가 있고, 종래보다 부품수가 줄어들므로 중량이 감소하고 조립의 효율성이 증가될 뿐 아니라 이에 따른 비용도 감소되는 효과가 있다.In addition, the purification efficiency is increased to increase the amount of pollutants to be purified in the catalytic converter assembly has an effect that the more purified exhaust gas is discharged, and the number of parts is reduced compared to the prior art to reduce the weight and increase the efficiency of assembly only But the cost is also reduced.

이러한 목적을 달성하기 위하여 본 발명은, 내부에 촉매를 포함하고 양측단부에 구비되는 제1 및 제2 촉매컨버터, 상기 제1 및 제2 촉매컨버터를 상호 연통시키는 유동가이드를 포함하는 것을 특징으로 하는 통합 언더플로어 촉매컨버터 조립체를 제공한다.In order to achieve the above object, the present invention comprises a first and a second catalytic converter including a catalyst therein and provided at both ends, and a flow guide for communicating the first and second catalytic converters with each other.

도 2는 본 발명의 일실시예로 통합 언더플로어 촉매컨버터 조립체를 도시한 그림이다.Figure 2 is a diagram showing an integrated underfloor catalytic converter assembly in one embodiment of the present invention.

본 발명은 종래의 WCC(10)와 UCC(20)를 통합한 새로운 형태의 촉매컨버터인 통합 언더플로어 촉매컨버터(UCC) 조립체(100)를 제시한다. 상기 통합 UCC 조립체(100)는 탄화수소(HC), 일산화탄소(CO), 질소산화물(NOx) 및 입자상물질(PM) 등의 오염물질을 정화시킬 수 있는 촉매컨버터를 일측단에 설치한 제1 촉매컨버터(110)와 상기 오염물질을 정화시킬 수 있는 촉매컨버터를 타측단에 설치한 제2 촉매컨버터(120)가 포함되고, 상기 제1 촉매컨버터(110)와 제2 촉매컨버터(120)를 상호 연통시키는 유동가이드(130)로 구성되어 하나의 촉매컨버터 조립체로 형성된다.The present invention proposes an integrated underfloor catalytic converter (UCC) assembly 100 which is a new type of catalytic converter integrating the conventional WCC 10 and the UCC 20. The integrated UCC assembly 100 includes a first catalytic converter installed at one end of a catalytic converter capable of purifying contaminants such as hydrocarbons (HC), carbon monoxide (CO), nitrogen oxides (NOx), and particulate matter (PM). And a second catalytic converter 120 having a catalytic converter capable of purifying the contaminant at the other end, and communicating the first catalytic converter 110 and the second catalytic converter 120 with each other. It consists of a flow guide 130 to form a single catalytic converter assembly.

종래의 촉매컨버터가 WCC(10)와 UCC(20)로 설치된 것은 배출되는 배기가스 오염물질의 정화성능을 높이기 위해 추가의 촉매컨버터가 설치된 것인데, 차량의 설치공간이 협소하여 상기 WCC(10)와 UCC(20)로 분리되어 설치된 것이다.Conventional catalytic converters installed with the WCC (10) and the UCC (20) is an additional catalytic converter is installed to increase the purification performance of the exhaust gas pollutant discharged, the installation space of the vehicle is narrow and the WCC (10) UCC 20 is installed separately.

마찬가지로 상기 통합형 UCC 조립체(100)의 경우에도 종래의 UCC(20)가 설치되는 공간에 설치되므로 공간이 협소하여 다량의 촉매가 포함된 하나의 촉매컨버터가 설치되지 못하고, 제1 촉매컨버터(110)와 제2 촉매컨버터(120)로 나뉜 형태의 통합형 UCC 조립체(100)로 설치된다.Similarly, since the integrated UCC assembly 100 is installed in a space in which the conventional UCC 20 is installed, the space is so narrow that one catalytic converter including a large amount of catalyst cannot be installed, and the first catalytic converter 110 is used. And a second type UCC assembly 100 divided into a catalytic converter 120 is installed.

그러므로 상기 통합 UCC 조립체(100)는 한 개의 촉매캐닝 안에 두 개의 촉매가 존재함으로 상기 제1 촉매컨버터(110)와 제2 촉매컨버터(120)에 각각 포함되는 촉매의 양은 배출되는 오염물질의 양에 따라 유기적으로 조절될 수 있고, 에미션 규제에 대응하는 것도 유리해진다. 즉, 상기 통합형 UCC 조립체(100)에 포함되는 전체 촉매의 양은 변하지 않지만, 상기 제1 촉매컨버터(110)와 제2 촉매컨버터(120)에 각각 포함되는 촉매의 양은 조절될 수 있기 때문에 상기 통합 UCC 조립체(100)는 경우에 따라 최적의 촉매정화성능이 발휘될 수 있다.Therefore, since the integrated UCC assembly 100 has two catalysts in one catalyst canning, the amount of catalyst included in each of the first catalytic converter 110 and the second catalytic converter 120 depends on the amount of pollutant discharged. This can be organically controlled, and it is also advantageous to respond to emission regulations. That is, the total amount of catalyst included in the integrated UCC assembly 100 does not change, but the amount of catalyst included in each of the first catalytic converter 110 and the second catalytic converter 120 may be controlled, so that the integrated UCC The assembly 100 may exhibit the optimum catalytic purification performance in some cases.

또한, 촉매가 활성화되기 위해서는 온도가 충분히 높아야 하지만, 촉매컨버터가 설치되는 위치에 따라 촉매컨버터의 온도는 다르며, 배기 매니폴드에 가까울수록 촉매는 온도가 빨리 상승되어 엔진이 가동될 때 많이 발생하는 HC를 줄이는데 유리하나, 온도가 과다하게 올라가면 오히려 촉매의 활성이 저하되는 경향이 있다. 그러므로 상기 통합 UCC 조립체(100)는 상기 배기 매니폴드에 가깝게 설치된 제1 촉매컨버터(110)와 상기 배기 매니폴드에서 상대적으로 멀리 설치된 제2 촉매컨버 터(120)를 조합하여 최적의 촉매정화성능이 발휘될 수 있다.In addition, the temperature must be high enough for the catalyst to be activated. However, the temperature of the catalytic converter varies depending on the location of the catalytic converter. The closer to the exhaust manifold, the faster the temperature of the catalyst increases, which causes HC to be generated when the engine is running. It is advantageous to reduce the temperature, but excessively high temperature tends to lower the activity of the catalyst. Therefore, the integrated UCC assembly 100 combines a first catalytic converter 110 installed close to the exhaust manifold and a second catalytic converter 120 installed relatively far from the exhaust manifold to provide an optimum catalytic purification performance. Can be exercised.

또한, 종래에는 WCC(10)와 UCC(20)로 두 개의 촉매컨버터가 사용됨에 따라 배기가스 규제에 따른 인증을 위한 절차에도 각각의 촉매컨버터에 대해 인증 절차를 받았으나, 본 발명의 통합 UCC 조립체(100)는 하나의 촉매컨버터 조립체에 대한 인증 절차만을 받으면 된다.In addition, in the related art, since two catalytic converters are used as the WCC 10 and the UCC 20, the certification procedure for each catalytic converter is also received for the certification according to the exhaust gas regulation, but the integrated UCC assembly of the present invention ( 100 only needs to be certified for one catalytic converter assembly.

도 3은 본 발명의 통합 언더플로어 촉매컨버터 조립체를 장착한 형태를 도시한 그림이다.Figure 3 is a view showing a form equipped with an integrated underfloor catalytic converter assembly of the present invention.

종래의 UCC(20)가 설치되는 위치에 본 발명의 통합 UCC 조립체(100)가 설치된다. 그러므로 터보차져(30)에서 종래의 UCC(20)까지의 거리보다 상기 통합 UCC 조립체(100)의 제1 촉매컨버터(110)까지의 거리가 짧아진다. 상기와 같이 촉매가 전진 배치되기 때문에 촉매활성화온도(LOT)의 도달시간이 단축되기 때문에 더욱 빨리 배기가스를 정화할 수 있다는 장점이 있다.The integrated UCC assembly 100 of the present invention is installed at the position where the conventional UCC 20 is installed. Therefore, the distance from the turbocharger 30 to the first catalytic converter 110 of the integrated UCC assembly 100 is shorter than the distance from the conventional UCC 20. As described above, since the catalyst is moved forward, the arrival time of the catalyst activation temperature LOT is shortened, and thus the exhaust gas can be purified more quickly.

또한, 유동가이드(130)의 길이는 조절될 수 있으므로 실제 차량에 설치되는 과정이 종래의 촉매컨버터가 설치되는 과정보다 간편해진다는 장점이 있다.In addition, since the length of the flow guide 130 can be adjusted, the process that is actually installed in the vehicle has the advantage that it is easier than the process of installing the conventional catalytic converter.

한편, 종래의 WCC(10)와 UCC(20)가 제거되고 상기 UCC(20)의 위치에 통합형 UCC 조립체(100)가 설치되므로 부품의 수가 줄어들고 그에 따라 전체적인 중량이 감소될 뿐 아니라, 조립과정이 간편해지므로 조립의 효율성이 증대된다는 장점이 있다.Meanwhile, since the conventional WCC 10 and the UCC 20 are removed and the integrated UCC assembly 100 is installed at the position of the UCC 20, the number of parts is reduced and thus the overall weight is reduced. The simplicity has the advantage of increasing the efficiency of assembly.
