Description

technical field [0001] The invention relates to the technical field of exhaust post-treatment of internal combustion engines, in particular to an electronic control device for a DPF diesel engine particulate filter system. Background technique [0002] Soot particles are one of the most important pollutants in the exhaust emissions of diesel engines. DPF (Diesel Particulate Fitter, Diesel Particulate Filter) diesel particulate filter system is currently the most effective device for reducing the emission of soot particles from diesel engines. The traditional DPF diesel particulate filter system electronic control device has a complex structure and high cost, and is not suitable for refitting vehicles that do not meet exhaust emission standards. Contents of the invention [0003] In view of the above technical problems, the object of the present invention is to provide an electronic control device for a DPF diesel particulate filter system, which is independent of the engin...
