CONTROL DEVICE OF INTERNAL COMBUSTION ENGINE

摘要

Disclosed is a control device of an internal combustion engine wherein desired torque can be achieved without receiving the influence of an operation state of a variable valve timing mechanism (IN-VVT) which changes valve timing of an intake valve. The control device of the internal combustion engine calculates a target air quantity for achieving the desired torque based on data which defines a relationship between torque and an air quantity in MBT in association with the operation state of the IN-VVT. When a throttle is operated such that the target air quantity is achieved, an actual air quantity which is to be actually achieved is calculated. The control device of the internal combustion engine calculates basic ignition timing from the actual air quantity based on data which defines a relationship between ignition timing and air quantity in the case where the IN-VVT is in the most retarded angle position. Moreover, an advance angle correction amount of the ignition timing is determined from the operation state of the IN-VVT, and final ignition timing is determined from the basic ignition timing and the advance angle correction amount.
