摘要： When executing a Local-learning, an air-fuel ratio detecting time is corrected so that a dispersion of detection values of an air-fuel ratio sensor becomes a maximum value in one cycle of an engine. While executing a cylinder-by-cylinder air-fuel ratio control, a Global-learning is executed. In the Global-learning, the air-fuel ratio detecting time is corrected based on a relationship between a variation in estimated air fuel ratio of each cylinder and a variation in fuel quantity correction value of each cylinder. In the Global-learning, a computer computes a correlation coefficient between the variation in estimated air-fuel ratio and the variation in fuel quantity correction value of the cylinder for each case where the cylinder assumed to correspond to the estimated air fuel ratio is hypothetically varied in multiple ways. Then, the air-fuel ratio detecting time is corrected so that this correlation coefficient becomes a maximum value.

摘要： A method, apparatus, and system to measure, record, and control exhaust products from an internal combustion engine (ICE) are disclosed. Measurements of the exhaust products of an ICE are recorded and made available.

摘要： The control apparatus for the internal combustion engine increases a fuel injection amount under predetermined conditions, such as after the start of the internal combustion engine, at cold time, at acceleration requiring time, at gear shifting time from a neutral to a D-range, for example. When the fuel injection amount is increased during execution of air/fuel ratio feedback control, the feedback control follows the increase amount, and executes correction corresponding to the increase amount. Then, at the point of time when the correction corresponding to the increase amount is completed, the increase of the fuel injection amount is stopped quickly. Thereby, the increase of the fuel injection amount is not continued unnecessarily, and therefore useless consumption of the fuel can be suppressed. Also, it becomes possible to start other controls early by finishing increase quickly. For example, when the canister purge is executed during the increase of the fuel injection amount, it is difficult to distinguish an evaporated fuel amount by purge and an increase amount by the fuel increase, and learning precision of a vapor concentration is lowered. Therefore, purge is not performed during the increase of the fuel injection amount, and the purge control is performed after the fuel increase is stopped quickly, whereby it becomes possible to start purge control early.

摘要翻译： 内燃机的控制装置在冷启动时，在加速需要时间，从中性到D档的换档时间等的预定条件下，增加燃料喷射量， 例如。 当在执行空燃比反馈控制期间燃料喷射量增加时，反馈控制遵循增加量，并且执行对应于增加量的校正。 然后，在对应于增加量的校正完成的时间点，燃料喷射量的增加被快速停止。 因此，燃料喷射量的增加不会不必要地延续，因此能够抑制燃料的无用的消耗。 此外，通过快速增长可以提前启动其他控件。 例如，当在燃料喷射量的增加期间执行罐吹扫时，难以通过吹扫来区分蒸发的燃料量和通过燃料增加来增加增加量，并且蒸气浓度的学习精度降低。 因此，在燃料喷射量的增加期间不进行吹扫，并且在燃料增加快速停止之后进行吹扫控制，从而可以提前开始吹扫控制。

摘要： A target value Vtgt for an output Vout of an O2 sensor 8 (an exhaust gas sensor) disposed downstream of a catalytic converter 4 is set variably depending on a temperature TO2 of an active element 10 of the O2 sensor 8 by a target value setting unit 18, and the air-fuel ratio of an exhaust gas is controlled by an air-fuel ratio control unit 17 to converge the output Vout to the target value Vtgt. An exhaust gas temperature Tgd is estimated by an exhaust temperature observer 19, and the temperature TO2 of the active element 10 is sequentially estimated by an element temperature observer 20 using the estimated value of the exhaust gas temperature Tgd. A heater 13 of the O2 sensor 8 is controlled by a heater controller 22 to keep the temperature TO2 of the active element 10 at a predetermined target value R. The air-fuel ratio is thus controlled to maintain a desired exhaust gas purifying capability of the catalytic converter irrespective of the temperature of the active element of the exhaust gas sensor.
