1. A method for operating an internal combustion engine, the method comprising:
actuating, during a valve overlap phase during at least one operational cycle of a start-up operation of the internal combustion engine, an injector to introduce a fuel into a combustion chamber of the internal combustion engine; and
avoiding complete combustion of the fuel introduced into the combustion chamber of the internal combustion engine by the injector;
wherein the internal combustion engine is configured to introduce a first gaseous fuel into the combustion chamber, and is configured to operate the injector based on a second liquid fuel.
