Title:
FILTER REGENERATION CONTROL DEVICE AND FILTER REGENERATION CONTROL METHOD
Document Type and Number:
WIPO Patent Application WO/2018/194160
Kind Code:
A1
Abstract:
A filter regeneration control device and a filter regeneration control method for preventing sulfur poisoning of a filter. An ECU (7) comprises: a concentration determination unit (110) which, when a filter regeneration implementation condition is satisfied, determines whether a sulfur concentration in fuel supplied to a diesel engine (1) or in exhaust gas is greater than or equal to a threshold value; and a regeneration control unit (120) which, if the sulfur concentration is not greater than or equal to the threshold value, controls a fuel injection device (6) to implement conventional filter regeneration. If the sulfur concentration is greater than or equal to the threshold value, the regeneration control unit (120) controls the fuel injection device (6) to implement special filter regeneration in which the value of at least one of fuel injection time and fuel injection amount is increased compared with the conventional filter regeneration.
