Abstract

In this paper it is proposed to solve the problem of particulate matter reducing apparatus of the current DPF. One exhaust gas passage 2-way controlled to purify the exhaust gas generated during combustion efficiently. Through the control of the rotary valve within a single device, it is possible to prevent the exhaust pressure increases due to particulate matter accumulate inside the developing DPF. Develop DPF device capable of inducing a high efficiency of the output in order to improve the problem of reducing the engine output and fuel efficiency.

본 논문에서는 현재 입자상물질 저감장치인 DPF의 문제를 해소하기 위하여 제안된 것으로서, 단일채널내의 배기가스 통로를 양방향 제어하여 연소시 발생되는 배기가스를 효율적으로 정화한다. 1개의 DPF장치를 장착하고 회전형 밸브를 교번제어 하여 DPF 내부에 입자상물질 적층현상으로 인한 배기가스의 내부압력 증가를 피할수 있고, 출력저하 및 연비효율이 떨어지는 등의 문제를 획기적으로 개선하여 고효율의 출력을 유도할 수 있는 입자상물질 정화시스템을 개발한다.
