Title:
SCRシステム
Document Type and Number:
Japanese Patent JP5471832
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide an SCR system capable of preventing ammonia slip when regenerating a DPF.SOLUTION: The SCR system has a harmonization control threshold map 131 referred by an SCR inlet temperature and an exhaust gas flowing quantity, a harmonization control threshold corrector 133 for correcting the harmonization control threshold obtained in the harmonization control threshold map 131 based on an exhaust gas temperature sensor and an outdoor air temperature detector, the harmonization controller starts the regenerating of the DPF when the calculated storage quantity becomes the harmonization control threshold after correction or less.
