A dual-fuel injection system having a combustion gas-supply device and a liquid fuel-supply device, including a combustion gas-injector unit with a liquid fuel-control part and a gas nozzle part, to which combustion gas can be supplied. The stroke of a gas nozzle needle of the combustion gas-injector unit can be controlled by liquid fuel supplied to the liquid fuel-control part. The combustion gas-injector unit defines a leakage collecting space, via which a leakage path is lead, the leakage path extending from the liquid fuel-control part into the gas nozzle part. The dual-fuel injection system has a pressure-regulating device, by which a defined pressure level can be set in the leakage collecting space. An implementation method using such a dual-fuel injection system is also proposed. |
