Title:
FILTER REGENERATION CONTROL SYSTEM FOR INTERNAL COMBUSTION ENGINE, AND FILTER REGENERATION CONTROL METHOD FOR INTERNAL COMBUSTION ENGINE
Document Type and Number:
WIPO Patent Application WO/2017/183399
Kind Code:
A1
Abstract:
When an amount of particulate matter sediment has exceeded a regeneration initiation threshold value, a control device initiates automatic regeneration; during automatic regeneration, the control device controls an internal combustion engine in a filter-regenerating combustion mode for raising the temperature of exhaust gas; and when an indicated target speed indicated from a target speed indicator is less than a regenerative lower-limit speed, the control device controls the lower-limit speed of the internal combustion engine to switch to either the indicated target speed or the regenerative lower-limit speed in accordance with the state of an operation locking unit, and controls a regeneration process execution unit in accordance with the temperature of a catalyst.
