Title:
内燃機関システム
Document Type and Number:
Japanese Patent JP6769281
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide an internal combustion engine system in which regeneration processing of a filter collecting a particulate substance can be efficiently and surely performed, even when performance of an oxidation catalyst is deteriorated by phosphorus poisoning.SOLUTION: The internal combustion system comprises a direct injection injector 13, an oxidation catalyst 27, an exhaust pipe injector 18, a DPF 20 and a control device 7. The control device 7 performs a regeneration processing of the DPF 20 by burning a particulate substance accumulated on the DPF 20 by controlling a ratio of a fuel injection amount by the exhaust pipe injector 13 and a post injection amount of the fuel by the cylinder injection injector 18 to a prescribed ratio when performance deterioration of the oxidation catalyst 27 is not detected, and performs the regeneration processing of the DPF 20 while increasing the ratio of the post injection amount of the fuel by the cylinder injection injector 13 in comparison with that in a case when the performance deterioration of the oxidation catalyst 27 is not detected, when the performance deterioration of the oxidation catalyst 27 is detected.SELECTED DRAWING: Figure 2
