摘要： A gas detection device includes: an element portion (40); a voltage applying unit (81) configured to apply a voltage (step-up, maintaining voltage constant at a voltage higher than the decomposition start voltage of sulfur oxides, step-down) across a first electrode (41a) and a second electrode (41b) on surfaces of a solid electrolyte (41s); a current detecting unit (91) configured to detect an output current flowing between the first electrode (41a) and the second electrode (41b); and a measurement control unit (20). The measurement control unit (20) acquires a parameter which has a correlation with a degree of change of the output current increasing as a concentration of sulfur oxides in an exhaust gas increases based on the output current during the voltage step-down, and performs determination of whether the concentration of sulfur oxides in the exhaust gas is equal to or higher than a predetermined value or detection of the concentration of sulfur oxides in the exhaust gas based on the acquired parameter.

摘要： The sulfur oxides detection system 1 comprises: a device part 10 comprising a first electrochemical cell 51 having a first solid electrolyte layer 11, a first electrode 41, and a second electrode 42; and a diffusion regulating layer 16; a power supply 61 supplying voltage between the electrodes; a detector 62 detecting a first current correlation parameter; and a control part 80 controlling the power supply and acquiring the first current correlation parameter. The control part 80 controls the power supply so that a first voltage is applied between the electrodes and calculates a concentration of sulfur oxides in the measured gas based on the first current correlation parameter detected by the detector when the first voltage is applied between the electrodes, but it does not calculate the concentration of sulfur oxides in the measured gas when it judges that a concentration of water in the measured gas is not stable.

摘要： In a limited-current type gas sensor which detects oxygen-containing gas contained in an exhaust gas of an internal combustion engine, the decomposition current value of water (H 2 O) is detected, and the existence of an abnormality of output characteristics of the limited-current type gas sensor is diagnosed based on its deviation from a reference decomposition current value of water corresponding to the concentration of water contained in the exhaust gas. Thereby, not only an oxygen sensor (air-fuel-ratio sensor), but also a NOx sensor and a SOx sensor can accurately and easily diagnose not only a remarkable abnormality of output characteristics, but also a minute abnormality thereof. In addition, the reference decomposition current value of water may be acquired based on the concentration of water detected by a separate humidity sensor or the decomposition current value of oxygen detected by the limited-current type gas sensor. In the latter case, the reference decomposition current value of water may be corrected based on a decomposition current value of oxygen detected during a fuel cut.
摘要翻译：在检测内燃机的废气中含有的含氧气体的有限电流型气体传感器中，检测出水分（H 2 O）的分解电流值，并且存在输出特性的异常有限电流型气体传感器基于其与对应于废气中所含的水的浓度的水的参考分解电流值的偏差进行诊断。因此，不仅氧传感器（空燃比传感器）以及NOx传感器和SOx传感器不仅可以准确且容易地诊断输出特性的显着异常，而且能够精确地诊断其微小异常。此外，可以基于由单独的湿度传感器检测的水的浓度或由限流型气体传感器检测的氧的分解电流值来获取水的参考分解电流值。在后一种情况下，可以基于在燃料切断期间检测到的氧的分解电流值来校正水的参考分解电流值。

摘要： The abnormality diagnosis system of an air-fuel ratio sensor comprising an exhaust purification catalyst, an upstream side air-fuel ratio sensor provided at an upstream side of the exhaust purification catalyst, a downstream air-fuel ratio sensor provided at a downstream side of the exhaust purification catalyst, and a diagnosis device diagnosing the downstream air-fuel ratio sensor for abnormality based on outputs of these air-fuel ratio sensors. The diagnosis device judges that the downstream air-fuel ratio sensor suffers from an abnormality if the output air-fuel ratio of the upstream side air-fuel ratio sensor has become a rich air-fuel ratio richer than a stoichiometric air-fuel ratio, and the output air-fuel ratio of the downstream air-fuel ratio sensor air-fuel ratio has changed from an air-fuel ratio richer than a lean judged reference air-fuel ratio to an air-fuel ratio leaner than the lead judged reference air-fuel ratio. As a result, it is possible to accurately diagnose an abnormality of a downstream air-fuel ratio sensor when using an air-fuel ratio sensor as a downstream side sensor.

摘要： This control device for an internal combustion engine includes: an exhaust purification catalyst (20) that is provided in an exhaust passage of the internal combustion engine; a downstream air-fuel ratio sensor (41) that is provided downstream of the exhaust purification catalyst; and an air-fuel ratio control device that controls such that the air-fuel ratio of exhaust gas flowing into the exhaust purification catalyst reaches a target air-fuel ratio. The downstream air-fuel ratio sensor is configured such that the applied voltage thereof at which the output current becomes zero decreases as the exhaust air-fuel ratio increases. If the target air-fuel ratio is richer than the reference air-fuel ratio, the voltage applied to the downstream air-fuel ratio sensor is set to a higher voltage than the voltage at which the output current becomes zero when the exhaust air-fuel ratio is the stoichiometric air-fuel ratio. If the target air-fuel ratio is leaner than the reference air-fuel ratio, the voltage applied to the downstream air-fuel ratio sensor is set to a lower voltage than the voltage at which the output current becomes zero when the exhaust air-fuel ratio is the stoichiometric air-fuel ratio. A control device for an internal combustion engine using an air-fuel ratio sensor that can reliably detect when the absolute value of the exhaust air-fuel ratio reaches a prescribed air-fuel ratio richer than the stoichiometric air-fuel ratio is thus provided.

摘要： In an exhaust path (4) of an internal combustion engine (2), a catalyst (6) including an oxygen storage capacity, a first air-fuel ratio sensor (10) installed upstream of the catalyst (6), and a second air-fuel ratio sensor (12) installed downward of the catalyst are disposed. An air-fuel ratio of the internal combustion engine (2) is controlled to a rich air-fuel ratio richer than a theoretical air-fuel ratio, or a lean air-fuel ratio leaner than the theoretical air-fuel ratio. In a state that is determined as a state where the catalyst (6) stores oxygen to an upper limit of an oxygen storage amount after the air-fuel ratio is switched to the lean air-fuel ratio from the rich air-fuel ratio, or a state where the catalyst (6) releases oxygen to a lower limit of the oxygen storage amount after the air-fuel ratio is switched to the rich air-fuel ratio from the lean air-fuel ratio, a first output that is the output of the first air-fuel ratio sensor (10), and a second output that is the output of the second air-fuel ratio sensor (12) are detected. Based on a difference between the first output and the second output, the output of the first air-fuel ratio sensor (10) is corrected.

摘要： Disclosed is a particulate matter detection device that detects the diameter and the amount of particulates in exhaust gas while reducing detection error caused by deterioration such as the deterioration of electrodes.
In the particulate matter detection device, which measures particulates in a gaseous body, AC voltages having different frequencies are applied to a pair of electrodes disposed apart from each other. The resulting impedances to the different frequencies are detected. A resistance component and/or a capacitance component of the impedances to the different frequencies are calculated. The average diameter and/or the number of particulates in the gaseous body are estimated in accordance with changes in the resistance component and/or the capacitance component.
