Description

차량용 디젤엔진 배기가스 저감장치의 쿨러.{Cooler of vehicle diesel engine waste gas reduction system.}Cooler of vehicle diesel engine waste gas reduction system. {Cooler of vehicle diesel engine waste gas reduction system.}

본 발명은 차량의 압축착화기관인 디젤엔진의 배기가스 저감장치의 쿨러에 관한 것으로, 특히 배기가스 저감장치에 열전소자를 부가하여 열화를 방지함으로써 배기가스의 저감효율을 좋게 한 차량용 디젤엔진 배기가스 저감장치의 쿨러에 관한 것이다.The present invention relates to a cooler of an exhaust gas reducing device of a diesel engine that is a compression ignition engine of a vehicle. In particular, a diesel engine exhaust gas reduction that improves exhaust gas reduction efficiency by adding a thermoelectric element to the exhaust gas reducing device to prevent deterioration is provided. Relates to the cooler of the device.

일반적으로 디젤기관은 열효율, 내구성, 신뢰성 등이 다른 기관에 비하여 우수하기 때문에 선박, 각종 산업기계, 자동차 등의 동력원으로 널리 사용되고 있으며, 특히 큰 출력을 얻을 수 있기 때문에 그 용도는 증가되고 있는 추세이다.In general, diesel engines are widely used as a power source for ships, various industrial machines, automobiles, etc. because they have superior thermal efficiency, durability, and reliability, compared to other engines. .

디젤엔진은 대기압보다 높은 압력의 흡기량 증대로 연료의 분사량이 상대적으로 증대되고, 따라서 배기가스 중의 유해성분 함량이 증가된다.In diesel engines, the injection amount of fuel is relatively increased by increasing the intake amount at a pressure higher than atmospheric pressure, thereby increasing the amount of harmful components in the exhaust gas.

한편, 배기매니폴드에 촉매 컨버어터가 설치됨으로써, 상기한 바와 같은 배기가스 중의 유해성분을 줄이기 위한 노력이 행해지고 있는데, 이와 같은 촉매컨버어터는 통로를 갖는 담체 표면에 백금 등의 귀금속으로 된 촉매를 부착시켜 촉매와 배기가스의 반응으로 배기가스에 함유된 유해성분을 중화시키는 것이다.On the other hand, since the catalytic converter is installed in the exhaust manifold, efforts have been made to reduce the harmful components in the exhaust gas as described above. Such a catalytic converter has a catalyst made of a precious metal such as platinum on the surface of the carrier having a passage. It attaches to neutralize harmful components contained in exhaust gas by reaction of catalyst and exhaust gas.

이러한 디젤기관은 배기가스중에 유해물질인 NOx 및 매연미립자 배출물의 함 유량이 높기 때문에 환경 오염 문제가 최우선시 되는 현재 이에 대한 해결 방안이 시급한 실정이다.Since diesel engines have a high content of NOx and particulate matter emissions in the exhaust gas, there is an urgent need for a solution to the current environmental pollution problem.

종래에는 디젤기관의 배기가스를 정화시키는 기술이 다양하게 제안되어 있으나 이것은 연료 분사기를 연장하여 NOx 배출온도를 낮춰주고 이에 따라 증가하는 HC,CO 등의 연소 미립자 배출물을 저감시킴으로서 연소 소비율 및 시동성 등을 향상시키는데 중점을 두었다.Conventionally, various techniques for purifying exhaust gas of diesel engines have been proposed. However, this method extends fuel injectors to lower the NOx emission temperature and thereby reduces combustion particulate emissions such as HC and CO, thereby improving combustion consumption rate and startability. Focused on.

그러나 일반적으로 NOx와 기타의 배출물은 교환조건 관계에 있기 때문에 NOx만을 저감시키기 위해 기관 자체를 개량하는데 중점이 맞춰진 종래의 배기가스 정화 수단은 이미 한계에 도달되어 있다.However, in general, since NOx and other emissions are in an exchange condition relationship, conventional exhaust gas purification means focused on improving the engine itself to reduce NOx only has already reached its limit.

또한 가솔린 기관에 있어서는 배기가스 저감대책으로서 3원 촉매에 의해 후처리 기술이 일반화되어 있으나 디젤 기관은 배기가스 중에 다량의 탄소가 포함되어 있고, 배기가스 온도가 낮으며, 매연 미립자의 부착 그리고 경유중의 유황분에 의하여 SOx가 생성되는 문제점 때문에 가솔린 엔진에서와 같은 후처리 기술을 적용할 수 없었다.In the gasoline engine, aftertreatment technology is generally used as a countermeasure to reduce the exhaust gas, the diesel engine contains a large amount of carbon in the exhaust gas, the exhaust gas temperature is low, the particulate matter is attached, and the diesel Due to the problem that SOx is generated by sulfur, it was not possible to apply the same aftertreatment technology as in gasoline engines.

따라서 기관자체에 의한 배출물의 대폭적인 저감이 곤란한 현단계에서는 현재 사용하고 있는 연료에 의지하는 한 오염물질을 그 발생과정인 연소과정에서 억제하거나 새로운 배기 후처리 기술을 개발하여야 하는데 오염물질을 그 발생과정에서 억제하는 것은 사실상 어렵기 때문에 디젤 기관에 적용할 수 있는 새로운 배기 후처리 기술이 절실히 요구되고 있는 실정이다.Therefore, in the present stage, when it is difficult to drastically reduce emissions by the engine itself, as long as it depends on the fuel used, it is necessary to suppress the pollutants during the combustion process or to develop a new exhaust aftertreatment technology. It is virtually difficult to restrain the process, so a new exhaust aftertreatment technology applicable to diesel engines is urgently needed.

이러한 배기 후처리 기술중 배기 재순환 방식(EGR; Exhaust Gas Recirculat ion)을 단순히 디젤기관에 적용하려고 하는 경우에는 EGR률의 증가에 따라 고부하 영역에서 NOx 이외의 배출물이 증가하게 되고, 연료 소비율도 증가하게 되며, 연소 미립자 및 SOx 배출물의 순환에 의하여 기관 내부가 마모되거나 침식되는 현상이 발생하는 등의 문제점이 제기되었다.In case of simply applying Exhaust Gas Recirculat ion (EGR) to diesel engines, the emission rate other than NOx increases in the high load region with increasing EGR rate. In addition, problems such as wear or erosion of the engine may occur due to the circulation of combustion particulates and SOx emissions.

상기한 바와 같은 종래의 단점을 해소하기 위하여 인젝터의 연료분사를 조절함과 아울러, 배기가스를 재연소시켜 궁극적으로 배기가스 중의 유해성분 함량을 줄일 수 있게 하는 디젤엔진의 배기가스 정화시스템을 제공함에도 불구하고 문제는 있다.In addition to controlling the fuel injection of the injector in order to solve the above-mentioned disadvantages, and to provide an exhaust gas purification system of a diesel engine that can re-burn the exhaust gas and ultimately reduce the harmful content of the exhaust gas. There is a problem though.

본 발명은 이와같은 점을 감안하여 안출한 것으로서 배기 후처리 기술인 배기 재순환 방식(EGR; Exhaust Gas Recirculation)에 있어서 디젤엔진 측으로 재순환되는 배기가스의 온도를 저감하여 유해성분을 효과적으로 감소시킬 수 있게 한 차량용 디젤엔진의 배기가스저감장치의 쿨러를 제공하는 것을 주목적으로 한다 The present invention has been made in view of the above, and in a vehicle exhaust gas recirculation (EGR; Exhaust Gas Recirculation) technology to reduce the temperature of the exhaust gas recycled to the diesel engine to reduce the harmful components effectively The main purpose is to provide a cooler for the exhaust gas reduction device of a diesel engine.
