Dual-fuel injection system (1) having a combustion gas-supply device (3) and a liquid fuel-supply device (5), comprising a combustion gas-injector unit (7) with a liquid fuel-control part (21) and a gas nozzle part (23), to which combustion gas can be supplied; wherein the stroke of a gas nozzle needle (27) of the combustion gas-injector unit (7) can be controlled by means of liquid fuel supplied to the liquid fuel-control part (21); wherein the combustion gas-injector unit (7) defines a leakage collecting space (53), via which a leakage path (57) is lead, said leakage path (57) extending from the liquid fuel-control part (21) into the gas nozzle part (23); and wherein the dual-fuel injection system (1) has a pressure-regulating device (63), by means of which a defined pressure level can be set in the leakage collecting space (53). An implementation method using such a dual-fuel injection system (1) is also proposed. |
