摘要： A control device for a spark-ignition internal combustion engine that sets ignition timing based on a target value of a predetermined combustion-related parameter correlated with a combustion state and operates an ignition device in accordance with the ignition timing thus set. The control device calculates an actual value of the combustion-related parameter from an output value of the cylinder pressure sensor and feeds back the calculated value of the combustion-related parameter to the setting of ignition timing. Further, in parallel with the above processing, the control device calculates a value of a predetermined combustion variation parameter correlated with the magnitude of combustion variation from the output value of the cylinder pressure sensor. If the calculated value of the combustion variation parameter deviates from an allowable range of the combustion variation, the control device stops the feedback of the calculated value of the combustion-related parameter.

摘要： The present invention relates to a control device for a spark-ignition internal combustion engine provided with a cylinder pressure sensor and aims to facilitate optimal control of a combustion state even in a situation where an operating condition is variable.A predetermined combustion-related parameter whose value is uniquely determined by behavior of a change in cylinder pressure relative to a crank angle is used as a control value. Ignition timing is calculated based on the control value in accordance with a calculation rule determined according to a current or target operating condition of the internal combustion engine. The control value resulting from calculation based on a target value of a predetermined physical quantity relating to torque of the internal combustion engine in accordance with a predetermined calculation rule is used as a base value and is corrected by feeding back an output value of the cylinder pressure sensor.

摘要： A fuel injection amount is controlled so that the air-fuel ratio of exhaust gas flowing into a catalyst (6) oscillates around a stoichiometric air-fuel ratio. When it is estimated that the level of oxygen storage capacity of the catalyst (6) is lower than a predetermined reference capacity, the amplitude of the air-fuel ratio of the exhaust gas which oscillates around the stoichiometric air-fuel ratio is reduced by controlling the fuel injection amount. The level of the oxygen storage capacity of the catalyst (6) is estimated based on the amplitude of the output signal from an oxygen sensor (14) disposed downstream of the catalyst (6).
