摘要： An air-fuel ratio imbalance among cylinders determining apparatus according to the present invention is applied to a multi-cylinder internal combustion engine in which a compression ratio is variable. The determining apparatus obtains, using at least an output value of an upstream air-fuel ratio sensor disposed for a catalyst, an “imbalance determining parameter” which becomes larger as a degree of an imbalance among “individual cylinder air-fuel ratios” becomes larger, each of the individual cylinder air-fuel ratios being an air-fuel ratio of a mixture supplied to each of cylinders. Further, the determining apparatus determines that an air-fuel ratio imbalance state among cylinders is occurring, when the imbalance determining parameter is larger than a predetermined threshold. The determining apparatus changes the predetermined threshold in accordance with a mechanical compression ratio of the engine.

摘要： A catalyst deterioration diagnosing apparatus is provided with means for performing stoichiometric feedback control on the air-fuel ratio based on at least output from an upstream air-fuel ratio sensor provided upstream of a catalyst, means for measuring the oxygen storage capacity of the catalyst, and means for correcting the measured value of the oxygen storage capacity based on at least the output behavior of a downstream air-fuel ratio sensor provided downstream of the catalyst during the stoichiometric feedback control. The measured value of the oxygen storage capacity is corrected using the output behavior of the downstream air-fuel ratio sensor during stoichiometric feedback control. The diagnostic is performed after eliminating the effects from sulfur by correcting the measured value to a value corresponding to when low sulfur fuel is used, which makes it possible to prevent an erroneous diagnosis from being made.

摘要： A cylinder-to-cylinder air/fuel ratio imbalance determination system obtains an imbalance determination parameter that increases or decreases as a difference between the air/fuel ratios of different cylinders increases, based on output values of an air/fuel ratio sensor, and makes a cylinder-to-cylinder A/F imbalance determination, based on the result of comparison between the imbalance determination parameter and a threshold value for imbalance determination. The determination system changes the amount of fuel injected into one or more of the cylinders so as to create a forced imbalance condition in which the air/fuel ratio of a particular cylinder deviates from the air/fuel ratio of the remaining cylinders, and obtains an air/fuel ratio sensor evaluation parameter (e.g., rate of change ΔAF of the detected air/fuel ratio) in this condition. Then, the determination system determines whether the air/fuel ratio sensor is adequate for making a cylinder-to-cylinder A/F imbalance determination, by comparing the evaluation parameter with a reference parameter (an evaluation parameter obtained based on output values of a reference air/fuel ratio sensor in the same forced imbalance condition).

摘要： An electronic control device calculates the maximum actual oxygen storage capacity of a catalyst. The gradient of a linear expression formed between the catalyst temperature and the maximum oxygen storage capacity of the catalyst is stored for each degradation level of the catalyst. The gradient can be learned in accordance with the same temperature of the catalyst and the maximum actual oxygen storage capacity. When the maximum actual oxygen storage capacity is calculated, it is revised in accordance with the temperature of the catalyst, a reference temperature, the linear expression, and the learned gradient. The revised maximum oxygen storage capacity which is the maximum oxygen storage capacity when the temperature of the catalyst during the same calculation period is equal to the reference temperature is then calculated. If a response delay is detected in the output of an oxygen sensor, the gradient of the learned linear expression is discarded.

摘要： An object of the present invention is to provide a technology that enables detection of a fault of a PM trapper with improved accuracy. In the present invention, a pressure sensor 20 that measures a differential pressure across a PM trapper 11 is provided, and a fault of a PM trapper is determined based on an amount of change in the differential pressure across the PM trapper 11 between two different operation states of an internal combustion engine 1 in which the ambient temperature around the pressure sensor 20 falls within a specific temperature range. Since variations in the offset error of the differential pressure sensor 20 caused by changes in the ambient temperature around the differential pressure sensor 20 is made small, the amount of change in the differential pressure across the PM trapper 11 can be measured more accurately, and a fault of the PM trapper 11 can be detected with improved accuracy.

摘要： A catalyst deterioration diagnosis system performs a diagnosis of deterioration of the oxidation catalyst based on a high-temperature-inflow-condition exhaust gas temperature and a low-temperature-inflow-condition exhaust gas temperature. The high-temperature-inflow-condition exhaust gas temperature is a temperature detected by a temperature sensor while the temperature of the exhaust gas that flows into the oxidation catalyst is in a high temperature region H while the reducing agent is supplied from the reducing agent supply means into the exhaust gas that flows into the oxidation catalyst. The low-temperature-inflow-condition exhaust gas temperature is a temperature detected by the temperature sensor while the temperature of the exhaust gas that flows into the oxidation catalyst is in a low temperature region L while the reducing agent is supplied from a reducing agent supply means into the exhaust gas that flows into the oxidation catalyst.

摘要： An inter-cylinder air-fuel ratio imbalance determination apparatus that obtains, based on an output value Vabyfs of an air-fuel ratio sensor, an air-fuel ratio fluctuation indicating amount (AFD) which becomes larger as an air-fuel ratio fluctuation of an exhaust gas passing through a position at which the air-fuel ratio sensor is disposed becomes larger, during a parameter obtaining period. The determination apparatus estimates an air-fuel ratio sensor element temperature (Temps) having a strong relation with responsiveness of the air-fuel ratio sensor during the parameter obtaining period, and obtains a corrected air-fuel ratio fluctuation indicating amount by correcting the AFD based on the estimated Temps. The determination apparatus adopts the corrected air-fuel ratio fluctuation indicating amount as the imbalance determination parameter X, and determines whether or not an inter-cylinder air-fuel-ratio imbalance state has been occurring based on a comparison between the imbalance determination parameter X and the imbalance determination threshold Xth.

摘要： The invention intends to provide a technology which makes it possible to diagnose with higher accuracy whether or not abnormality occurs in a filter regeneration system causing excessive execution frequency of a regeneration process. The filter regeneration system initiates execution of the regeneration process, incase an estimated particulate matter (PM) accumulation amount at the filter reaches a pre-determined regeneration requiring accumulation amount; or in case the pressure upstream of the filter or the differential pressure across the filter reaches a pre-determined regeneration requiring value, the value being larger than the pressure or the differential pressure corresponding to the regeneration requiring accumulation amount. Then, the diagnosis is carried out based on a ratio of an estimated PM accumulation amount at the initiation of the execution of the regeneration process to the regeneration requiring accumulation amount.
