Abstract:
1. A control device of an internal combustion engine provided with a fuel injector which injects fuel to the inside of an intake port and an exhaust variable valve timing mechanism able to change a valve timing of an exhaust valve, when conditions for executing early exhaust valve closing control stand, the control device executing early exhaust valve closing control which advances a closing timing of the exhaust valve so as to make combustion gas in a combustion chamber flow back into an intake port when an intake valve opens, wherein the control device is further provided with a torque detecting means for detecting an output torque which is output by an engine body and, wherein 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 said torque detecting means will become smaller than the limit torque.
