  • Patent number: 8249793
    Abstract: An amount of fuel injected into an internal combustion engine is controlled to adjust an air-fuel ratio. An air-fuel ratio sensor is disposed upstream of a three-way catalyst. An ammonia sensor is disposed downstream of the three-way catalyst. Main feedback control based on the air-fuel ratio sensor is performed such that the air-fuel ratio of exhaust gas becomes close to a target air-fuel ratio in the neighborhood of a stoichiometric air-fuel ratio. Sub-feedback control is performed on the basis of an output value of the ammonia sensor.

  • Patent number: 8033168
    Abstract: A catalyst deterioration judgment device that can accurately perform a catalyst deterioration judgment by considering an oxygen density at downstream of an exhaust purification catalyst. The system reads outputs of an oxygen sensor and an ammonia sensor that are installed in downstream of an NSR catalyst when the catalyst is in an activate condition. When this read oxygen sensor output is equal to or more than a reference value and the ammonia sensor output is equal to or more than a reference value, it is estimated that ammonia oxidizing reaction does not occur under existence of oxygen in the NSR catalyst. In this case, the NSR catalyst is judged to be deteriorated.

  • Publication number: 20110126523
    Abstract: An object of this invention is to prevent components such as NOx and H2S being emitted when starting a vehicle and improve exhaust emissions by utilizing information of a navigation system. A navigation system mounted in the vehicle is connected to an ECU. The ECU predicts whether a stopping time of the internal combustion engine is near based on the current position and travel history of the vehicle obtained from the navigation system. When a stopping time is near, the ECU executes rich spike control prior to the stopping time to thereby perform a regeneration process of the NOx catalyst. Thus, NOx components or sulfur components remaining in the catalyst can be eliminated before stopping the internal combustion engine. Accordingly, even if warming up is performed when the engine is next started, emission of NOx or hydrogen sulfide can be avoided.

  • Publication number: 20110088377
    Abstract: In an exhaust purification device of an internal combustion engine, a pair of upstream side NOx storage catalysts storing NOx contained in the exhaust gas when the air-fuel ratio of the inflowing exhaust gas is lean and releasing the stored NOx when the air-fuel ratio of the inflowing exhaust gas becomes the stoichiometric air-fuel ratio or rich are arranged inside an engine exhaust passage. At the downstream side of the upstream side NOx storage catalysts, a downstream side NOx storage catalyst is arranged. The upstream side NOx storage catalysts and downstream side NOx storage catalyst are formed so that the spatial velocity in the downstream side NOx storage catalyst becomes larger than the spatial velocities in the upstream side storage catalysts.
