摘要： This control device for an internal combustion engine is equipped with: an air/fuel ratio sensor; and an engine control device that controls the internal combustion engine according to the output of the air/fuel ratio sensor. The air/fuel ratio sensor is configured so that the applied voltage at which the output current reaches zero varies according to the exhaust air/fuel ratio, and the output current increases if the applied voltage is increased at the air/fuel ratio sensor when the exhaust air/fuel ratio is the stoichiometric air/fuel ratio. When the air/fuel ratio of exhaust gas is to be detected by the air/fuel ratio sensor, the applied voltage at the air/fuel ratio sensor is fixed at a constant voltage, said constant voltage being different to the voltage at which the output current reaches zero when the exhaust air/fuel ratio is the stoichiometric air/fuel ratio, and being the voltage at which the output current reaches zero when the exhaust air/fuel ratio is different to the stoichiometric air/fuel ratio. Thus provided is a control device for an internal combustion engine that uses an air/fuel ratio sensor capable of detecting an absolute value for the air/fuel ratio of exhaust gas even if the air/fuel ratio of the exhaust gas is not the stoichiometric air/fuel ratio.

摘要： Disclosed is a method for correcting characteristic variation of a PM sensor and improving detection accuracy of the sensor. The PM sensor has a pair of electrodes for capturing the PM in an exhaust gas, and a sensor output changes in accordance with a captured amount of the PM. If the sensor output gets close to a saturated state, the PM combustion control for combusting and removing the PM is executed. If a zero-point output of the PM sensor is to be corrected, first, a sensor output at a point of time when predetermined time required for combustion of the PM has elapsed after electrical conduction to the heater is started by the PM combustion control is obtained. Then, the sensor output at an arbitrary point of time is corrected. As a result, correction of the sensor can be made smoothly by using existing PM combustion control.

摘要： A device, which detects information about a hydrogen concentration level, includes an air-fuel ratio sensor, an air-fuel ratio controller, and a detecting portion. The detecting portion calculates either a ratio of response periods or a difference between the response periods to detect the hydrogen concentration level. One of the response periods is a period from the time the air-fuel ratio controller switches the target air-fuel ratio from rich to lean to the time the air-fuel ratio sensor detects this. The other of the response periods is a period from the time the air-fuel ratio controller switches the target air-fuel ratio from lean to rich to the time the air-fuel ratio sensor detects this. This allows the decisions of a variation between cylinders and an exhaust purifying catalyst degradation.

摘要： 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.
