ABSTRACT:
In an internal combustion engine provided with a variable valve mechanism that varies at least a valve operating characteristic (valve lift amount, valve operating angle and the like) of an intake valve, a target volume flow ratio equivalent to a target torque of the engine is obtained to be converted into a valve opening area, and a target valve operating characteristic of the variable valve mechanism is set based on the converted valve opening area, to control the variable valve mechanism so that an actual valve operating characteristic reaches a target valve operating angle, thereby executing with high accuracy an intake air amount control mainly by the variable valve mechanism.
