CONTROL DEVICE OF INTERNAL COMBUSTION ENGINE |
摘要 |
An internal combustion engine control device the present invention provides is a control device that can realize both of request torque and a request A/F for each of cylinder groups with high precision, even when the request A/F differs at each of the cylinder groups. The present control device sets a reference A/F within a range from the leanest A/F to the richest A/F out of the request A/Fs to the respective cylinder groups. The present control device calculates a target air quantity for realizing the request torque under the reference A/F, based on data that defines a relation between engine output torque and an air quantity in relation to an A/F. The present control device controls a throttle opening in accordance with the target air quantity, and controls fuel injection amounts of the respective cylinders in accordance with the request A/F s to the respective cylinder groups. |
