Title:
EXHAUST EMISSION CONTROL METHOD AND EXHAUST EMISSION CONTROL DEVICE
Document Type and Number:
Japanese Patent JP3463647
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To reliably remove fine particles, in an exhaust emission control method and an exhaust emission control device which adopts a new method.
SOLUTION: A particulate filter 22 is arranged in an engine exhaust passage. The discharge amount of fine particles per unit time to be discharged from a combustion chamber 5 is made smaller than the oxidizable and removal amount of fine particles per unit time oxidizable and removal, without generating luminous flames on the particulate filter 22, and allordingly, the fine particles in exhaust gas are oxidized and removed without generating luminous flames, when they to flow into the particulate filter 22. When it is predicted that the temperature of the particulate filter become lower than the preset temperature for the preset time or more, the temperature of the particulate filter is raised.
