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： Disclosed is an intake air volume measuring device for an internal combustion engine. The device includes an air flow meter located in an intake air path of the internal combustion engine, to measure the volume of intake air into the combustion chamber of the internal combustion engine based on an output signal of the air flow meter. The output signal of the air flow meter (AFM signal) is sampled in synchronism with the crank angle of the internal combustion engine. With this angle-synchronous processing, the device is capable of obtaining AFM data at equal intervals within a cycle of intake air pulsation, thereby eliminating adverse effects of the intake air pulsation. The device is hence capable of reducing variations in AFM data averages and calculating average flow rates of the intake air with high precision.

摘要： A moisture adsorbing device 1 comprising a type Y zeolite, and an NO x adsorbing device 2 being put in place on an exhaust-gas downstream side of the moisture adsorbing device 1, and comprising a zeolite that includes a transition metal ion in the cation exchange sites are included. In NO x adsorbing apparatuses, since the less the moisture content in exhaust gases is the more the NO x adsorbing capability improves, the NO x adsorbing capability in low-temperature region is improved especially by means of the combination with a moisture adsorbing device that comprises a type Y zeolite whose Al 2 O 3 proportion is great and whose moisture adsorbing amount is great compared with the other zeolites.
