Title:
内燃機関の排気浄化装置
Document Type and Number:
Japanese Patent JP4193778
Kind Code:
B2
Abstract:
An exhaust emission control device of an internal combustion engine limiting traveling of a vehicle when PM forced regeneration processing is carried out, in which lowering of a regeneration efficiency is suppressed while limitation of traveling due to PM forced regeneration processing is prevented from being prolonged. In the inventive exhaust emission control device of an internal combustion engine limiting traveling of a vehicle when PM forced regeneration processing is carried out, when execution time of forced regeneration processing exceeds a predetermined time, limitation of traveling is released and PM forced regeneration processing is sustained so long as regeneration conditions are satisfied, thus preventing limitation of a traveling from being prolonged while minimizing lowering of a regeneration efficiency.
