摘要： A combustion system (100), a control module (104) for a combustion system (100) and a method of operating the combustion system (100) are disclosed. The method may be implemented by the control module (104) in the combustion system (100). The method comprises predicting an iced condition of the pressure sensor assembly (240); responsive to predicting the iced condition, controlling exhaust emissions without using a pressure parameter sensed with the pressure sensor assembly (240) in the iced condition; predicting a de-iced condition of the pressure sensor assembly (240); and responsive to predicting the de- iced condition, controlling the exhaust emissions using the pressure parameter sensed with the pressure sensor assembly (240) in the de-iced condition..

摘要： Downstream side air-fuel ratio sensor signal based adaptive air-fuel ratio control. When the air-fuel ratio detected by the downstream side air-fuel ratio sensor is maintained lean unduly, a stuck learning control is performed to decrease a learning value to lower the air-fuel ratio. Adaptive learning value update control is performed based on the downstream side air-fuel ratio sensor signal to increase the learning value when an upstream air-fuel ratio deviates to the rich side and to decrease the learning value when the upstream air-fuel ratio deviates to the lean side. It is judged that the downstream side air-fuel ratio sensor is abnormal when a certain value or more of decrease of the learning value and a certain value or more of increase of the learning value are repeated.

摘要： In an internal combustion engine, a hydrocarbon feed valve (15), NO x storage catalyst (13), particulate filter (14), and electric resistance type sensor (29) are arranged in an engine exhaust passage in this order from an upstream side. The electric resistance type sensor (29) generates an output value corresponding to the amounts of deposition of particulate matter and hydrocarbons which are contained in the exhaust gas and deposited at the sensor part thereof. From the change of the output value of the electric resistance type sensor (29), it is judged if the hydrocarbons have slipped through the NO x storage catalyst (13) and if the particulate matter has slipped through the particulate filter (14).

摘要： A method includes raising a temperature of an SCR catalyst for a predetermined time period while dosing urea. The method further includes maintaining the temperature of the SCR catalyst without dosing urea for a second predetermined time period. The method further includes filtering out at least low frequency data from a first NO
x sensor upstream of the SCR catalyst and from a second NO
x sensor downstream of the SCR catalyst, and comparing the filtered data from the first NO
x sensor and the second NO
x sensor without dosing urea over a third predetermined time period. The method further includes providing a NO
x sensor condition index for at least one of the first NOx sensor and the second NO
x sensor in response to the comparing.

摘要： When a measurement trigger which is outputted at an every predetermined time after start of an engine is detected, a sensor outputting a signal in relation to concentration of a liquid reducing agent on the basis of a characteristic of heat transmission between two points apart from each other within the liquid reducing agent storage tank is triggered to measure concentration of the liquid reducing agent. Each of the number of times of determination of no liquid reducing agent, that is, the number of times concentration is successively determined to be equal to or higher than an upper limit threshold, and the number of times of determination of a solution of a different kind, that is, the number of times concentration is successively determined to be equal to or lower than a lower limit threshold is counted. When the number of times of determination of no liquid reducing agent becomes equal to or larger than the predetermined value, it is determined that no liquid reducing agent remains. When the number of times of determination of a solution of a different kind becomes equal to or larger than the predetermined value, it is determined that the liquid reducing agent is a solution of a different kind. When the number of times of determination of no liquid reducing agent and the number of times of determination of a solution of a different kind is less than the predetermined value, it is determined that the liquid reducing agent is correct one.

摘要： In a compression ignition internal combustion engine provided with an NOx storage-reduction catalyst on an exhaust system, when the air fuel ratio of the exhaust gas being in a lean state is controlled to a rich state, a response time (ResS) from a time point an air fuel ratio sensor detects a first air fuel ratio (AF1), which is leaner than a stoichiometric air fuel ratio (AFS), to a time point the air fuel ratio sensor detects a second air fuel ratio (AF2), which is equal to or leaner than the stoichiometric air fuel ratio (AFS) and richer than the first air fuel ratio (AF1). When the response time (ResS) exceeds a stoichiometric air fuel ratio shift reference time (StdS), a determination is made that the air fuel ratio sensor is degraded.
