Abstract:
A method for introducing fuel into a combustion chamber of an internal combustion engine is provided, in which fuel is injected at variable metering directly into the combustion chamber by a first fuel injector on the one hand, and into an air aspiration channel leading to the combustion chamber by a second fuel injector on the other hand. To ensure a reliable cold start of the internal combustion engine when using regenerative fuels even at low temperatures, in the cold start of the internal combustion engine a partial quantity of the required overall fuel quantity is injected via the second fuel injector, this partial quantity being the particular fuel quantity that exceeds a maximum fuel quantity able to be injected via the first fuel injector.
