Abstract: 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.

An ECU (40) performs multiple first injections to each produce an air-fuel mixture of a lean air-fuel ratio in the combustion chamber (23) before an ignition in one combustion cycle of the engine, and performs a second injection to produce an air-fuel mixture of a rich air-fuel ratio in the combustion chamber (23) before the ignition and after the first injection. In particular, the ECU implements the multiple first injections in such a manner that the first injection implemented early among the multiple first injections produces an air-fuel mixture leaner than that of the first injection implemented subsequently. The ECU implements the second injection only once immediately before an ignition timing.
