摘要： There are provided an adsorption amount sensor which is capable of accurately detecting an amount of hydrocarbons or water adsorbed by a zeolite of a hydrocarbon adsorber, even during operation of an engine, as well as a coking sensor which is capable of accurately detecting an amount of coke deposition on inner surfaces of a pipe of an internal combustion engine, even during operation of an engine. The adsorption amount sensor has a plurality of electrodes arranged in the vicinity of the hydrocarbon adsorber in a manner opposed to each other and each carrying a zeolite thereon. The amount of hydrocarbons adsorbed is detected by using a parameter indicative of changes in at least one of a resistance value between the electrodes and an electrical capacitance between the electrodes. The coking sensor has a plurality of electrodes arranged within the pipe of the engine in a manner opposed to each other and each having a surface thereof coated with an insulating material. The amount of coke deposition is detected by using a parameter indicative of changes in at least one of a resistance value between the electrodes and an electrical capacitance between the electrodes.

摘要： An adsorbent state determining apparatus is provided for accurately determining the state of an adsorbent including a deterioration as well as for allowing for recovery of the adsorbent if its adsorbent performance can be restored. The adsorbent state determining apparatus determines the state of an adsorbent for adsorbing hydrocarbons contained in exhaust gases. An upstream and a downstream temperature sensor are provided at upstream and downstream locations of the adsorbent in an exhaust system for detecting temperatures of exhaust gases upstream and downstream of the adsorbent. An engine water temperature sensor detects an operating state of the engine. An ECU estimates the temperature of the exhaust gas which should be detected downstream of the adsorbent during adsorption of the adsorbent based on the upstream temperature detected by the upstream temperature sensor and an engine water temperature of the engine detected by the engine water temperature sensor. The ECU then compares the estimated downstream temperature with the detected downstream temperature detected by the downstream temperature sensor during adsorption of the adsorbent to determine the adsorption state of the adsorbent.

摘要： A system for purifying exhaust gas generated by an internal combustion engine having a bypass exhaust gas passage branching from an exhaust pipe which is opened or closed by a switch-over valve, and an adsorbent which adsorbs unburneds component in the exhaust gas installed at the bypass exhaust passage. In the system, when the engine operation is within a high engine speed and high load region, the switch-over valve is operated to open the bypass exhaust gas passage to reduce noise due to switch-over valve chattering, etc. Similarly, the bypass exhaust gas passage is opened at that range, when the exhaust gas temperature is greater or equal to a predetermined value, to introduce high temperature exhaust gas to burn away cloggy material adhered to the adsorbent which would otherwise deteriorate or degrade the adsorbent.

摘要： A system for detecting malfunctions of an exhaust switch-over valve of an internal combustion engine, which opens/closes a bypass exhaust gas passage branched from an exhaust pipe of the engine and storing an adsorbent that adsorbs unburned components of the exhaust gas generated by the engine when the engine is started. In the system, the entrance temperature and the exit temperature in the bypass exhaust gas passage are detected and compared with each other in a first detection period when the passage is opened and in a second detection period when the passage is closed. Based on this comparison, it is determined whether the valve malfunctions. Alternatively, the valve malfunction is determined by comparing the valve opening/closing state with an instruction to operate the valve. With this, little time lag exists in the detection, thereby improving malfunction detection accuracy.

摘要： An object system for generating an output signal of an O2 sensor from a target air-fuel ratio is expressed as a model including a response delay element and a dead time element. Data of identified values of parameters of the model are sequentially generated by an identifier. Data of an estimated value of the output signal of the O2 sensor after a dead time of the object system is sequentially generated by an estimator. The target air-fuel ratio is generated according to an adaptive sliding mode control process performed by a sliding mode controller using the data of the identified and estimated values. The air-fuel ratio of an internal combustion engine is manipulated on the basis of the target air-fuel ratio according to a feed-forward control process.

摘要： A first exhaust gas sensor 5 (air-fuel ratio sensor) and a second exhaust gas sensor 6 (O2 sensor) are disposed respectively upstream and downstream of a catalytic converter. An exhaust system E which ranges from the exhaust gas sensor 5 to the exhaust gas sensor 6 and includes the catalytic converter 3 is regarded as an object exhaust system E, and a behavior of the object exhaust system E is modeled. When an internal combustion engine 1 is in operation, parameters to be set of the model of the object exhaust system E are sequentially identified based on the data of outputs of the exhaust gas sensors 5, 6. A deteriorated state of the catalytic converter 3 is determined based on the data of the identified values. Concurrent with the determination of the deteriorated state, a target air-fuel ratio for the internal combustion engine 1 is sequentially determined in order to converge the output of the exhaust gas sensor 5 to a given target value, and the air-fuel ratio of the internal combustion engine 1 is controlled to converge the output (the detected value of the air-fuel ratio) of the first exhaust gas sensor 5 to the target air-fuel ratio, for thereby allowing the catalytic converter 3 to achieve an optimum purifying capability. In this manner, the deteriorated state of the catalytic converter 3 can be determined in various operation states of the internal combustion engine 1 while keeping the purifying capability of the catalytic converter 3.
