Capturing the particulate which is discharged from the regenerative temperature control equipment and the regenerative temperature control

摘要

PROBLEM TO BE SOLVED: To provide a regeneration temperature control device for an exhaust gas cleaning filter capable of preventing worsening of fuel economy when regenerating the exhaust gas cleaning filter.;SOLUTION: The regeneration temperature control device for the exhaust gas cleaning filter has an unburnt component state detecting means for detecting the accumulated state of unburnt components accumulated on the exhaust gas cleaning filter which captures particulate ejected from an engine to prevent ejection to the atmosphere (steps S34, S35), and a filter regeneration temperature control means for controlling the regeneration temperature of the exhaust gas cleaning filter based on the accumulated state of unburnt components on the exhaust gas cleaning filter (steps S4-S7).;COPYRIGHT: (C)2007,JPO&INPIT
