Title:
CONTROL DEVICE FOR INTERNAL COMBUSTION ENGINE
Document Type and Number:
Japanese Patent JP2003003894
Kind Code:
A
Abstract:
To provide a control device robust in various condition changes such as the change of air density in the control of a fuel lead type internal combustion engine.
This control device is provided with a detection means for directly or indirectly detecting the change of air density. Based on the detection result by the above means, the maximum value of a target fuel amount is corrected, etc., to adjust the relation of the target fuel amount with an accelerator opening. Further, taking into consideration the fuel amount as an internal loss maintenance portion and the maximum value of the target fuel amount, both shaft torque amount and target fuel amount are determined.
