Control apparatus and control method of internal combustion engine |
摘要 |
In an internal combustion engine provided with a variable valve mechanism that varies a valve operating characteristic (valve lift amount and valve operating angle) of an intake valve, the valve operating characteristic of the intake valve is detected and an intake air amount controlled by the intake valve is calculated based on the detected valve operating characteristic. Then, a change (change rate, change amount) between the newest intake air amount calculation value and a past intake air amount calculation value is calculated, and the newest engine controlled variable is calculated based on the change and engine controlled variable (basic fuel injection quantity and the like) set in the past, and then the calculated newest engine controlled variable is output for executing an engine control.
