EXHAUST EMISSION CONTROL SYSTEM

摘要

PROBLEM TO BE SOLVED: To provide an exhaust emission control system having high collection efficiency of particulates corresponding to various engine operation conditions, in exhaust emission control systems burning and removing particulates contained in exhaust gas of a diesel engine.

SOLUTION: Collection efficiency of particulate in the diesel particulate filter 4 is improved by changing a domain of exhaust gas flowing in the diesel particulate filter 4 according to engine operation conditions by an exhaust gas flowing in domain control means 5 arranged in a front stage of the particulate filter 4.
