  • Patent number: 8943799
    Abstract: In a control device for an internal combustion engine including an air-fuel ratio sensor that includes a catalyst layer that covers an exhaust gas-side electrode, an oxygen storage capacity of the catalyst layer is acquired based on a sensor output of the air-fuel ratio sensor. The sensor output is corrected if the oxygen storage capacity is higher than a predetermined value and the sensor output is in a predetermined range in the vicinity of the theoretical air-fuel ratio. Preferably, the oxygen storage capacity is calculated by integrating the product of a deviation amount ?A/F of the sensor output with respect to the theoretical air-fuel ratio and a dwell time thereof. A correction period in which a correction operation is performed is set based on the oxygen storage capacity.

  • Publication number: 20140250993
    Abstract: An oxygen amount (an oxygen storage amount OSA) stored by metal cerium during a storage cycle is obtained based on an output value of an A/F sensor in a time period immediately before an exhaust air-fuel ratio (a downstream side A/F) detected by the A/F sensor shifts to a lean region, and degradation relating to OSC of the three-way catalyst is detected. In the storage cycle, a target air-fuel ratio is set so that an air-fuel ratio of exhaust emission flowing into an S/C changes from rich to lean. Therefore, the downstream side A/F shifts from stoichiometry to the lean region at a time after reaching stoichiometry. When the three-way catalyst degrades, the downstream side A/F shifts to the lean region from stoichiometry at a time. Therefore, the calculated oxygen storage amount OSA becomes extremely smaller as compared with that at a normal time.

  • Patent number: 8793060
    Abstract: A control apparatus controls an automatic stop of an engine mounted on a vehicle so as to automatically stop the engine if a predetermined stop condition is satisfied, the stop condition including a condition that a running speed of the vehicle is a prescribed speed or less. The control apparatus includes a prediction unit and a prohibition unit. The prediction unit predicts whether or not the next automatic stop time of the engine is less than a prescribed time capable of obtaining a fuel saving benefit based on a history of a vehicle stop time or an automatic stop time of the engine. The prohibition unit prohibits the next automatic stop of the engine if the prediction unit predicts that the next automatic stop time of the engine is less than the prescribed time.

  • Publication number: 20130276431
    Abstract: In this invention, an EMF oxygen sensor is subjected to an activation process applying unidirectional voltage between an atmosphere electrode and an exhaust electrode thereof. A control device controlling the oxygen sensor in which a voltage was applied with the atmosphere electrode being positive, additionally applies unidirectional voltage between the electrodes to make the atmosphere electrode positive, for example, when the oxygen sensor was used under an environment in which the air-fuel ratio of the internal combustion engine was rich relative to the theoretical air-fuel ratio. Conversely, A control device controlling the oxygen sensor in which a voltage was applied to make the atmosphere electrode negative, additionally applies unidirectional voltage between the electrodes to make the atmosphere electrode negative, for example, when the oxygen sensor was used under an environment in which the air-fuel ratio was lean relative to the theoretical air-fuel ratio.

  • Patent number: 8512531
    Abstract: The present invention relates to a gas concentration detection apparatus for detecting the concentration of a specific gas component in an exhaust gas emitted from an engine, and forms a deterioration judgment about the gas concentration detection apparatus accurately and immediately. After excess oxygen is discharged by an oxygen pump cell 2, a NOx concentration detection apparatus, judges whether a NOx sensor 1 is activated. If the NOx sensor 1 is not activated yet, an output increase rate Vu(t) of the NOx sensor cell output N during an increase process of the NOx sensor cell output N is acquired. The present invention judges whether the output increase rate Vu(t) is lower than a predetermined reference value Vth1. If the obtained judgment result indicates that Vu(t)<Vth1, the NOx sensor cell 4 is deteriorated.

  • Patent number: 8486166
    Abstract: Fuel reforming catalysts 28 generate a hydrogen-containing reformed gas when they come into contact with exhaust gas that contains a reforming fuel. Upstream and downstream air-fuel ratio sensors 58, 60 are respectively installed upstream and downstream of the fuel reforming catalysts 28. The upstream air-fuel ratio sensor 58 outputs a upstream sensor signal in accordance with oxygen concentration. The downstream air-fuel ratio sensor 60 outputs a downstream sensor signal in accordance with oxygen concentration and hydrogen concentration by using zirconia's oxygen detection capability and a change of a diffusion layer's hydrogen-concentration-dependent oxygen detection capability. An ECU 50 detects the hydrogen concentration without being affected by the oxygen concentration through the use of the upstream sensor signal in which only the oxygen concentration is reflected and the downstream sensor signal in which the oxygen concentration and hydrogen concentration are reflected.

  • Patent number: 8402812
    Abstract: It is an object of the present invention to provide a gas concentration detection apparatus that is capable of forming an accurate activity judgment when a gas concentration detection cell begins to detect gas concentration with high accuracy. When warm-up begins at time t0 in a NOx concentration detection apparatus that achieves NOx concentration detection with a NOx sensor cell after excess oxygen is discharged by an oxygen pump cell, a NOx sensor cell output begins to rise at time t1. Subsequently, at time t2, an oxygen pump cell output begins to rise. An inflection point appearing in the NOx sensor cell output is then located. At time t5 at which the inflection point appears, an activity judgment about the NOx sensor cell is formed.
