Method of Filter Regeneration Based On Index Application and Post Treatment Exhaust Contamination Gas Decreasing System In Vehicle

摘要

The variable application method filter regeneration control method applied to the vehicle post-treatment system 10 of the present invention includes one or more of a vehicle speed, a brake, a speed change stage, a clutch, an exhaust temperature, and an engine speed detected when the vehicle is driven by the controller 20. It is applied as a filter rapid regeneration variable, and the filter regeneration of the DPF (Diesel Particulate Filter) is separated from the automatic regeneration of the set cycle. Manual regeneration may be eliminated by eliminating the cause, and especially in fast regeneration, the DPF specification (ie, size and amount of precious metal) is maintained, so that the filter regeneration is inconvenient and fuel efficiency is deteriorated. It has the characteristics to be resolved.
