Abstract

Provided is a control device for an internal combustion engine capable of avoiding deterioration of combustion and reliably suppressing synthetic noise of a high pressure fuel pump and a fuel injection valve without affecting an operating state of the internal combustion engine. Therefore, when it is determined that there is synthetic noise of a high pressure fuel pump and a fuel injection valve, an operating angle of a variable valve mechanism provided in the internal combustion engine is made variable while satisfying a fuel injection request of the fuel injection valve.
