EXHAUST EMISSION CONTROL METHOD

摘要

PROBLEM TO BE SOLVED: To timely remove particulate deposited on the surface of a particulate filter from the particulate filter. SOLUTION: Particulate in exhaust emission is oxidized and removed on a particulate filter 22. At the time of starting an internal combustion engine, the temperature of the particulate filter is raised to a particulate oxidizing possible temperature so that the particulate deposited on the particulate filter can be oxidized.
