Development of Replace Controller for Diesel Particulate Filter with Carbonized Micro Wood Fiber Filter Core

摘要

To solve the problem that the diesel particulate filter with carbonized micro wood fiber filter core (CMWF DPF) must be replaced when the amount of captured particulate material is up to a certain level, the working principle and controlling requirements of the filter of carbonized micro wood fiber was studied and a replaced controller for CMWF DPF based on AT89C52 was designed. In this study, the signal acquisition, data calculation and analysis were introduced.
