Abstract
An internal-combustion engine includes: a direct fuel injector directly injecting fuel into a combustion chamber; and a control device. The control device performs: presumption processing that presumes, based on an operating condition of the internal-combustion engine, that a thermoplastic deposit is formed on an injection hole portion of the direct fuel injector; temperature control processing that increases a temperature of the injection hole portion when the thermoplastic deposit is presumed to be formed; and first removal processing that injects the fuel from the direct fuel injector after the temperature control processing.
