摘要： By raising a temperature of an element portion of a particulate matter sensor (8) that is arranged in an exhaust passage (4) of an internal combustion engine (2), a heat generation amount that results from the combustion of particulate matters is detected, during a removal treatment of removing, through combustion, particulate matters that are deposited on the element portion. Besides, an amount of particulate matters that are deposited on the element portion of the particulate matter sensor (8) is detected on the basis of an output of the particulate matter sensor (8), before the start of this removal treatment. On the other hand, an amount of particulate matters that are deposited on the element portion before the start of the removal treatment is detected in accordance with the heat generation amount. Furthermore, it is determined whether or not there is an abnormality in the particulate matter sensor (8), on the basis of a difference between a first particulate matter amount that is detected on the basis of the output of the particulate matter sensor (8) and a second particulate matter amount that is detected on the basis of the heat generation amount.

摘要： 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. The control apparatus maintains the element section in the predetermined temperature range after burning and removing the particulate matter until the internal combustion engine stops.

摘要： According to the invention, a particulate matter sensor is installed in an exhaust passage of an internal-combustion engine. A control unit for this internal-combustion engine detects a particulate amount in an exhaust gas through the exhaust passage in response to an output from the particulate matter sensor. Further, the control unit for the internal-combustion engine forms a particulate layer on electrode surfaces of the particulate matter sensor by applying a particulate capturing voltage between the electrodes during a first period. Further, the control unit maintains the formed particulate layer during a second period. It is noted here that the phrase “maintain the formed particulate layer” includes the meanings “maintaining the formed particulate layer as it is” and “inhibiting control to remove the particulate layer”.

摘要： An internal combustion engine includes an SCR system disposed on an exhaust passage and a particulate matter sensor disposed downstream of the SCR system, the particulate matter sensor for producing an output that corresponds to an amount of particulate matter deposited on an element section. A control apparatus for the internal combustion engine includes: means for detecting a condition of the element section being deposited with a urea-related substance; and means for controlling to bring a temperature of the element section to a first temperature range when the condition of being deposited with the urea-related substance is detected. The first temperature range is higher than a temperature at which the urea-related substance vaporizes and lower than a temperature at which the particulate matter burns. This prevents the urea-related substance from being deposited on an electrode of the particulate matter sensor and limits variations in an output of the particulate matter sensor.

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.
