Methods For Controlling The Operation Of A Particulate Filter |
摘要 |
A method of controlling the operation of a particulate filter in an exhaust gas after-treatment system may comprise calculating a ratio of particulate loading rate to filter regeneration rate using a mass-based soot load estimation scheme and comparing the ratio of particulate loading rate to filter regeneration rate to a predetermined threshold value. The method may further comprise controlling operating conditions of the particulate filter to maintain the ratio of particulate loading rate to filter regeneration rate at a value above the predetermined threshold value.
