Abstract

In a fuel supply system for a spark-ignition internal combustion engine having a blow-in valve for each cylinder for blowing an easily ignitable mixture of a liquid fuel and a combustion gas via a blow-in nozzle into a combustion chamber of the internal combustion engine, the blow-in valve has a pressure connection for supplying pressurized combustion gas to a blown-in nozzle from an external pressure source, and the blow-in valve has a piston/cylinder unit for delivering the liquid fuel for injection into the cylinder together with the combustion gas, with a plunger being provided for an at least indirect actuation of a nozzle needle of the blow-in nozzle controlling the injection of a metered quantity of fuel and the combustion gas into the combustion chamber.
