초록

본 논문에서는 유해배출물질 저감장치인 DPF의 문제를 해소하기 위하여 제안된 것으로서, 양방향으로 분기되는 배기가스 유로를 통하여 자동차의 엔진 구동시 발생되는 배기가스를 효율적으로 유도하고 2개의 DPF 장치를 장착함으로서 교번작용을 통한 유해배출물질 정화 및 재생연소특성을 효율적으로 적용할 수 있도록 개발한다. DPF 내부에 입자상물질 적층현상으로 인한 배기가스의 내부압력 증가를 피할 수 있고, 출력저하 및 연비효율이 떨어지는 등의 문제를 획기적으로 개선하여 고효율의 출력을 유도할 수 있는 자동차 배기가스 정화 시스템을 제공하려는데 그 목적이 있다.

In this paper, it is proposed to solve the problem of the harmful exhaust gas reduction device DPF. The exhaust gas is effectively guided through the control of the exhaust gas flow path which is separated in both directions. Through cross control of two DPF units, it helps to improve the purification and regeneration combustion characteristics of harmful emissions. It is possible to prevent an increase in internal pressure caused by deposition of particulate matter in the DPF. It is also an object of the present invention to provide an automobile harmful exhaust gas reduction device capable of solving the problem of lowering the output and lowering the fuel consumption.
