EXHAUST-GAS REDUCING DEVICE, AND A CONTROL METHOD THEREFOR

摘要

The present invention relates to an exhaust-gas reducing device and to a control method therefor. More specifically, it relates to an exhaust-gas reducing device of enhanced durability, which uses both a burner and a metal filter and is thereby able to regenerate the filter within a short time at high temperatures, which is constituted in such a way that the burner operates during idling of the vehicle, and which is capable of effective regeneration by forming a flame in a stable fashion by using a dispersion means. The present invention also relates to a control method for such an exhaust-gas reducing device.
