Variable valve control apparatus for internal combustion engine and method thereof |
摘要 |
An open-close characteristic of an intake valve is controlled so that a target intake air amount for an engine can be obtained, and also a retarded angle limitation of closing timing of an exhaust valve is set based on opening timing of the intake valve, to control an open-close characteristic of the exhaust valve so that the closing timing of the exhaust valve becomes a more advance angle side than the retarded angle limitation.
