Abstract
An electronic control unit that controls a variable operation angle mechanism that varies an operation angle of an intake valve reduces an operation angle of the intake valve to a normal startup operation angle after first maintaining the operation angle of the intake valve at a high temperature restart operation angle that is larger than the normal startup operation angle for a predetermined period of time after an engine is stopped.
Claims7
A control apparatus of a variable operation angle mechanism that varies an operation angle of an intake valve, comprising:
- a control unit that, after the operation angle is maintained at a high temperature restart operation angle that is larger than a normal startup operation angle for a first predetermined period of time, after an engine is stopped, reduces the operation angle to the normal startup operation angle.
Dependencies are inferred from the claim text.
