Patent ID: 7779796

Claim:
A variable valve actuating apparatus for an internal combustion engine with an exhaust turbocharger, the variable valve actuating apparatus comprising: an intake valve characteristic varying section arranged to receive a first control signal, and vary at least an opening timing and a closing timing of an intake valve of the internal combustion engine in accordance with the first control signal; an exhaust valve characteristic varying section arranged to receive a second control signal, and vary at least an opening timing of an exhaust valve of the internal combustion engine in accordance with the second control signal; and a control section configured to: identify a desired value of an output of the internal combustion engine; and perform a valve characteristic control process in response to an increase in the desired value of the output, the valve characteristic control process including: advancing the opening timing of the intake valve, and retarding the closing timing of the intake valve, by outputting the first control signal to the intake valve characteristic varying section; and advancing the opening timing of the exhaust valve by outputting the second control signal to the exhaust valve characteristic varying section.
