Diesel Particulate Filter

디젤엔진 매연저감장치(DPF)   |   Diesel Particulate Filter (DPF)

Product Tpye Explanation
Igniter / 이그나이터 필터에 축적된 미세먼지를 태우기 위한 점화원
An ignition source for burning the fine dust accumulated in the filter
Thermocouple / 온도센서 DPF 안 내부의 온도를 측정하기위해 DPF 하나에 총 3~4개의 온도센서를 장착함
A total of three to four temperature sensors are mounted in one DPF to measure the temperature inside the DPF.
pressure sensor / 압력센서 DPF에 PM(particulate matter)이 일정량 쌓이면 압력차가 발생하며, 이를 측정해 연료를 분사하여 PM을 연소함
When a certain amount of PM (particulate matter) accumulates in the DPF, a pressure difference occurs, and the PM is burned by measuring the fuel and injecting fuel
OBD(On-board Diagnostics) / OBD 자가진단장치 온도센서와 압력센서에서의 정보를 DPF에 장착된 ECU의 전자제어 작동조건을 실시간 모니터링하는 시스템임
It is a system that monitors information of temperature sensor and pressure sensor in real time of electronic control operating condition of ECU mounted in DPF.
