  • Patent number: 6799558
    Abstract: An internal combustion engine having one injection valve (3) per cylinder and at least one additional port injector (5) for injecting fuel into combustion air which is fed to the cylinders (2) in the intake tract (4). The port injector (5) havs two supply inlets (10, 11) which can be closed off. A control unit (8) determines the quantity of fuel which is to be delivered as a function of the operating state of the internal combustion engine (1). Separately provided starting fuel is delivered by the port injector (5) during the warm-up phase of the internal combustion engine.
