Title: Exhaust emission control device for internal combustion engine
Inventor: UEDA HIROYOSHI
IPC: F01N3/24
Filed: 2017-03-16
Abstract: PROBLEM TO BE SOLVED: To control an air-fuel ratio of gas flowing into an exhaust emission control catalyst to a theoretical air-fuel ratio during operation of a heat hydrogen generating device.SOLUTION: An exhaust emission control device for an internal combustion engine includes: a heat hydrogen generating device (50) capable of generating reformed gas including hydrogen; an NOocclusion catalyst (14) disposed in an engine exhaust passage; and an NOsensor (24) disposed downstream of the NOocclusion catalyst (14). An output value from the NOsensor (24) increases along with increase in the amounts of NOand ammonia included in gas. By supplying reformed gas from the heat hydrogen generating device (50) to the NOocclusion catalyst (14), NOoccluded from the NOocclusion catalyst (14) is emitted. At this time, if an actual output value from the NOsensor (24) is lowered to a reference output value of the NOsensor (14) or lower, a determination that reforming efficiency of the heat hydrogen generating device (50) has been deteriorated is made.SELECTED DRAWING: Figure 13
