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： A fuel injection amount control apparatus of an embodiment according to the present invention comprises an air-fuel ratio sensor 56 which is disposed between an exhaust gas aggregated portion HK and a three-way catalyst 43, and which outputs an output value corresponding to an amount of oxygen and an amount of unburnt substances contained in an exhaust gas that has reached an exhaust-gas-side electrode layer via a porous layer (diffusion resistance layer). This control apparatus obtains an actual detected air-fuel ratio by correcting the output value of the air-fuel ratio sensor 56 based on an alcohol concentration of a fuel detected by the alcohol concentration sensor 59 and an air-fuel ratio imbalance indicating value representing a degree of a non-uniformity among cylinder-by-cylinder air-fuel ratios. The control apparatus feedback controls on a fuel amount in such a manner that the actual detected air-fuel ratio coincides with a target value.

摘要： A present exhaust purifying apparatus comprises a SCR catalyst, a urea-water injector, and a downstream air-fuel ratio sensor (an oxygen concentration sensor having a diffusion resistance layer) disposed at a position downstream of the SCR catalyst. The present apparatus, when a predetermined condition is satisfied, stops injecting the urea-water from the urea-water injector, and obtains an output value of the downstream air-fuel ratio sensor, as a first output value, in that state. The present apparatus obtains an output value of the downstream air-fuel ratio sensor when the urea-water is being injected from the urea-water injector, as a second output value. The present apparatus obtains a concentration of ammonia which flows out from the SCR catalyst based on the difference between the first output value and the second output value.

摘要： In the present invention, 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. Further, the control apparatus for an internal combustion engine maintains the element section in the predetermined temperature range after burning and removing the particulate matter until the internal combustion engine stops. The element section can be free from the particulate matter deposition after the particulate matter is burned and removed. The particulate matter can thus be immediately detected in the start of the next operation of the internal combustion engine.
摘要翻译：在本发明中，内燃机的控制装置根据设置在内燃机的排气通路内的颗粒物质传感器的电极的电特性来检测排气通路内的废气中所含的颗粒物质的量发动机。术语“电性”是指随沉积的颗粒物质的量而变化的性质，例如当施加预定电压时的电流值。在启动内燃机并且完成颗粒物质量的检测之后，颗粒物质传感器的元件部分被设定在预定的温度范围。因此，沉积在元件部分上的颗粒物被燃烧和除去。此外，内燃机的控制装置在燃烧和除去颗粒物质直到内燃机停止之前将元件部分保持在预定温度范围内。在颗粒物被燃烧和除去之后，元件部分可以没有颗粒物质沉积。因此，可以在内燃机的下一次运转开始时立即检测出颗粒物。

摘要： An inter-cylinder air-fuel ratio imbalance determination apparatus (determination apparatus) according to the present invention obtains, based on the output value of the air-fuel ratio sensor 67, an air-fuel ratio fluctuation indicating amount whose absolute value becomes larger as a fluctuation of the air-fuel ratio of the exhaust gas passing through a position at which the air-fuel ratio sensor is disposed becomes larger, and further obtains an imbalance determination parameter which becomes larger as an absolute value of the air-fuel ratio fluctuation indicating amount becomes larger. In addition, the determination apparatus obtains an average value of the air-fuel ratio of the exhaust gas during a period in which the imbalance determination parameter is being obtained, and obtains an imbalance determination threshold which becomes smaller as the average value of the air-fuel ratio is closer to the stoichiometric air-fuel ratio. The determination apparatus determines that an inter-cylinder air-fuel ratio imbalance state has been occurring when the imbalance determination parameter is larger than the imbalance determination threshold.

摘要： An exhaust gas sensor that simultaneously exhibits enhanced water soak resistance and functionality, that is multilayered and exposed to a space in an exhaust path. The exhaust gas sensor includes: an electrolyte layer, positioned between an exhaust electrode and an atmosphere electrode; an atmospheric layer formation layer formed toward the atmosphere electrode to form an atmospheric layer to which the atmosphere electrode is exposed; a porous diffusion resistance layer formed toward the exhaust electrode to control flow rate of an exhaust gas reaching the exhaust electrode; and a porous trap layer formed to cover the entire section exposed to the space in the exhaust path. The trap layer includes a first trap layer, which covers a region near a gas inlet/outlet section of the diffusion resistance layer, and a second trap layer, which covers another region that covered by the first trap layer. The first trap layer is thinner than the second trap layer.

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.
