Title: Control device of internal combustion engine
Inventor: KORENAGA SHINGO
IPC: F02D43/00
Filed: 2015-07-23
Abstract: PROBLEM TO BE SOLVED: To prevent the deterioration of an exhaust characteristic when a change of an air-fuel ratio to a theoretical air-fuel ratio side is required to an internal combustion engine which is in an operation at a lean mode, related to a control device of the internal combustion engine.SOLUTION: An internal combustion engine having a NOx occlusion reduction catalyst at an exhaust passage is controlled. When the NOx which is occluded to the NOx occlusion reduction catalyst reaches discharge thresholds 76, 84, rich control for discharging the NOx is performed. In a state that an air-fuel ratio of an air-fuel mixture belongs to a second region which is approximate to a lean limit, the discharge threshold 76 for determining a start of the rich control is set in the vicinity of a NOx occlusion capacity of the NOx occlusion reduction catalyst. When the air-fuel ratio of the air-fuel mixture intrudes into a first region which is approximate to a theoretical air-fuel ratio, the discharge threshold 84 is changed to a smaller value.SELECTED DRAWING: Figure 9
