In a method for operating an internal-combustion engine, a fuel/air mixture is fed to a combustion chamber of the internal-combustion engine and is ignited therein. At least for a defined period during the starting and/or warm-up of the internal-combustion engine, at least some of the liquid fuel is replaced with fuel which is in vapor form and is ignited in the at least one combustion chamber of the internal-combustion engine. The fuel which is in vapor form is taken from at least one fuel tank, which is connected to the internal-combustion engine, above a liquid-fuel level and/or from a charcoal canister which is connected to the fuel tank.
