摘要： A control apparatus for an internal combustion engine detects an amount of particulate matter contained in an exhaust gas in an exhaust passage, according to an electrical property across electrodes of a particulate matter sensor disposed in the exhaust passage of the internal combustion engine. The term “electrical property” here refers to a property that changes with the amount of particulate matter deposited, for example, a current value of when a predetermined voltage is applied. After the internal combustion engine is started and detection of the amount of the particulate matter is completed, an element section of the particulate matter sensor is set to a predetermined temperature range. The particulate matter deposited on the element section is thereby burned and removed. The control apparatus maintains the element section in the predetermined temperature range after burning and removing the particulate matter until the internal combustion engine stops.

摘要： Disclosed is a control device, which controls an air-fuel ratio sensor that is mounted in an exhaust path of an internal-combustion engine. The air-fuel ratio sensor is capable of pumping oxygen in a gas. Normally (time t0-t1, time t3 or later), a positive voltage Vp1 is applied to a sensor element (FIG. 7A), and the air-fuel ratio is calculated (FIG. 7C) in accordance with a sensor current (FIG. 7B). A heater is driven after internal-combustion engine startup to heat the sensor element. In a process in which the sensor element temperature rises, a negative voltage Vm, which is oriented in a direction different from that of the positive voltage Vp1, is applied to the sensor element.

摘要： An oxygen concentration sensor is disposed in an engine exhaust passageway. The alcohol concentration in the fuel used in the internal combustion engine is detected. A target impedance is set on the basis of the detected alcohol concentration. The actual impedance of a sensor element of the oxygen concentration sensor is detected. The heater output of the exhaust gas sensor is controlled so that the actual impedance becomes equal to the target impedance, whereby the temperature of the sensor element represented by the impedance becomes equal to a target temperature represented by the target impedance.

摘要： An inter-cylinder air-fuel ratio imbalance determination apparatus that obtains, based on an output value Vabyfs of an air-fuel ratio sensor, an air-fuel ratio fluctuation indicating amount (AFD) which becomes larger as an air-fuel ratio fluctuation of an exhaust gas passing through a position at which the air-fuel ratio sensor is disposed becomes larger, during a parameter obtaining period. The determination apparatus estimates an air-fuel ratio sensor element temperature (Temps) having a strong relation with responsiveness of the air-fuel ratio sensor during the parameter obtaining period, and obtains a corrected air-fuel ratio fluctuation indicating amount by correcting the AFD based on the estimated Temps. The determination apparatus adopts the corrected air-fuel ratio fluctuation indicating amount as the imbalance determination parameter X, and determines whether or not an inter-cylinder air-fuel-ratio imbalance state has been occurring based on a comparison between the imbalance determination parameter X and the imbalance determination threshold Xth.

摘要： The invention has an object to provide a device for determining activation of an exhaust gas sensor which accurately determines a time at which an exhaust gas sensor output is usable, and can suppress an adverse effect caused by use of the exhaust gas sensor output including a large effect of adsorbed species. A time is measured from a time point when a temperature of an air-fuel ratio sensor 48 reaches a predetermined temperature T1, while the air-fuel ratio sensor 48 is warmed up. When the time becomes a predetermined target holding time Te or more, the air-fuel ratio sensor 48 is determined as being in an activation state. The target holding time Te is preferably set at such a length that all adsorbed species adsorbed onto the air-fuel ratio sensor 48 are desorbed, and areas around a sensor element section 50 are completely replaced with an exhaust gas.

摘要： An oxygen sensor generating an accurate output concerning low-concentration exhaust gas positioned downstream of a three-way catalyst. The oxygen sensor includes an exhaust gas side electrode exposed to an exhaust gas; a reference gas side electrode exposed to a reference gas serving as a reference for oxygen concentration; and an electrolyte positioned between the exhaust gas side electrode and the reference gas side electrode. Further, a reduction mechanism positioned toward a front surface of the exhaust gas side electrode ensures the ratio of the amount of exhaust gas introduced to the exhaust gas side electrode to the amount of an exhaust gas flow to the outside of the oxygen sensor is smaller than the ratio of the amount of exhaust gas introduced to an electrode for the air-fuel ratio sensor to the amount of an exhaust gas flow to the outside of the air-fuel ratio sensor.
