Ignition timing is calculated, when the engine is determined to be in an intense combustion mode, such that a largest in-cylinder pressure angle at which in-cylinder pressure becomes largest converges to a target angle, whereas when the engine is determined to be in a weak combustion mode, the same is calculated by feedback, based on the target angle and combustion state parameters indicative of a combustion state in the cylinder.

摘要： An air-fuel ratio controlling apparatus includes an internal pressure detector for detecting an internal pressure of a combustion chamber of the engine. The apparatus estimates a motoring pressure of the engine and determines a start-of-combustion time, a time point when a difference between the internal pressure and the motoring pressure exceeds a predetermined value in a compression stroke and a combustion stroke of the engine. Firing delay for each cylinder is calculated from as a duration from sparking to the start-of-combustion time. Air-fuel ratio of each cylinder is estimated based on the firing delay and fuel injection amount for each cylinder is calculated to make the air-fuel ratio of plural cylinders uniform.

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 control system for an internal combustion engine having a catalyst arranged in the exhaust system is disclosed. In the control system, catalyst temperature rise accelerating control is executed by increasing the intake air amount immediately after starting of the engine and retarding the ignition timing to make the rotational speed of the engine coincide with a target rotational speed. The air-fuel ratio of an air-fuel mixture supplied to the engine is controlled to a lean region with respect to the stoichiometric ratio immediately after starting of the engine. The degree of making the air-fuel ratio leaner is suppressed when the retard amount of the ignition timing during the execution of the catalyst temperature rise accelerating control is less than a predetermined retard amount.

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.

摘要： The values of parameters of a model of an object exhaust system including a catalytic converter are identified from the data of outputs from an air-fuel ratio sensor and an O2 sensor which are disposed respectively upstream and downstream of the catalytic converter while an internal combustion engine associated with the catalytic converter is in operation. A deterioration evaluating parameter representing the degree of variation of time-series data of the identified parameters is determined from the time-series data of the identified parameters. The deteriorated state of the catalytic converter is evaluated based on the deterioration evaluating parameter.
