It is a technology about

2021년 초 환경부 발표에 의하면, 매연저감장치를 부착한 차량의 운행 실태를 특별 점검한 결과, 디젤 입자상물질 필터(DPF)를 부착한 차량 88대 점검에서 저감장치 필터 훼손·파손 5대, 필터 클리닝의 미실시 17대 등 총 22대(25%)를 적발로 인해 디젤 입자상물질 필터(DPF)의 관리가 미흡한 상태임을 드러났다.According to the announcement of the Ministry of Environment in early 2021, as a result of a special inspection of the driving condition of vehicles equipped with a particulate matter filter (DPF), 88 vehicles equipped with a diesel particulate matter filter (DPF) were inspected, 5 filters were damaged or damaged, and the filter was cleaned. A total of 22 units (25%), including 17 units that were not carried out, were caught, revealing insufficient management of the diesel particulate matter filter (DPF).

디젤 입자상물질 필터(DPF)의 부착 후 45 ~ 75일 이내에 진행되는 성능유지를 위한 확인검사에 합격 시 3년간 정밀검사에서 면제가 되나 아직은 관리시스템이 없어 성능유지를 위한 확인검사 이후에 장치 성능을 유지하거나 관리 상태를 확인을 하는 것이 불가능한 상태이다. If you pass the confirmation test for performance maintenance within 45 to 75 days after attaching the diesel particulate matter filter (DPF), you will be exempted from the detailed inspection for 3 years. It is impossible to maintain or check the management status.

한편, 질소산화물(NOX)의 저감성능을 유지하기 위해서는 요소수의 주입이 필수적이나, 택배로 요소수를 제공하므로 요소수의 보충 확인이 불가하고, 소유자의 변경, 주소 이전으로 미 제공되는 사례가 빈번하게 발생되고 있어 요소수의 적기보충을 확인하고 요소수의 보충을 유도하기가 불가능한 상태이다.On the other hand, in order to maintain the reduction performance of nitrogen oxides (NO X ), injection of urea water is essential, but since urea water is provided by courier, supplement confirmation of urea water is not possible, and cases in which it is not provided due to change of owner or relocation of address is occurring frequently, making it impossible to confirm timely replenishment of urea and to induce replenishment of urea.

이를 해결하기 위해 질소산화물(NOX)의 농도 및 저감율과, 운행시간 및 거리와, 요소수의 양 및 분사량을 실시간으로 모니터링하여 요소수의 미주입시 문자발송, 안내전화를 하고 있지만, 요소수의 주입에 대한 강제성이 없어 요소수를 적기에 보충하도록 유도하기가 아직도 불가능한 상태이다.In order to solve this problem, the concentration and reduction rate of nitrogen oxides (NO X ), the driving time and distance, and the amount and injection amount of urea water are monitored in real time, and text messages are sent and information calls are made when urea water is not injected. There is no compulsion for injection, so it is still impossible to induce timely replenishment of the number of urea.

그러므로, PM 및 질소산화물(NOX)의 저감율과 저감장치의 작동상태 정보를 수집할 수 있고, 요소수의 미보충 상태와 불량 요소수의 사용 상태를 확인할 수 있으며, 매연저감장치와 SCR 시스템의 임의 탈거와 고장 여부를 확인할 수 있고, 관제센터에서 실시간 모니터링하여 차량 소유자 또는 저감장치 제작사로 조치를 위한 통보를 할 수 있으며, 요소수의 부족과 불량 요소수 사용과 매연저감장치와 SCR 시스템의 고장 및 임의 탈거 감지 시 액셀 페달의 출력을 제한하여 요소수의 정상 사용과 저감장치 정비를 유도할 수 있는 운행자동차 배출가스 저감장치 관리시스템의 개발이 절실히 요구되고 있는 실정이다.Therefore, it is possible to collect information on the reduction rate of PM and nitrogen oxides (NO X ) and the operating state of the reduction device, and to check the unsupplemented state of urea water and the use state of defective urea water. Optional removal and failure can be checked, and the control center can monitor in real time to notify vehicle owners or reduction device manufacturers for action. And there is an urgent need for the development of a management system for a vehicle's exhaust gas reduction device that can induce normal use of urea water and maintenance of the reduction device by limiting the output of the accelerator pedal upon detection of arbitrary detachment.
