METHOD AND DEVICE FOR REGENERATING NOx OCCLUSION APPARATUS

摘要

PROBLEM TO BE SOLVED: To provide a method and device for regenerating a NOx occlusion apparatus.

SOLUTION: This invention relates to the method and the device for regenerating the NOx occlusion apparatus connected to an exhaust pipe of an engine. An actuator drives a throttle valve to a first position when regeneration of the NOx occlusion apparatus is required. The first position is a position to perform regeneration of the NOx occlusion apparatus. The actuator drives the throttle valve to a second position while regeneration of the NOx occlusion apparatus is required further. The second position is a position for regenerating the NOx occlusion apparatus with opening the throttle valve wider than the first position.
