| description | An internal combustion engine is provided with a fuel injector 13 which injects fuel into an intake port 8 and an exhaust variable valve timing mechanism A which can change a valve timing of an exhaust valve 9. A control device executes early exhaust valve closing control which advances a closing timing of an exhaust valve when conditions for executing early exhaust valve closing control stand. Further, the control device is provided with a torque detecting means which detects an output torque which is output by an engine body 1. At the time of a deceleration operation of the internal combustion engine, even when the condition for executing early exhaust valve closing control stands, execution of the early exhaust valve closing control is prohibited when it is predicted that the output torque which is detected by the torque detecting means will become smaller than the limit torque. Due to this, due to execution of the early exhaust valve closing control, a large torque fluctuation is prevented from occurring at the time of a deceleration operation of the internal combustion engine etc. |
