To provide a method for reducing NOx by diluting fuel using a fuel diluting device.
The fuel diluting device to be used in this method includes a first pipe line having an inlet and an outlet and fitted for sending a fuel flow entering from the inlet and outflowing from the outlet under a first thermodynamic state and a first fuel index; and a second pipe line having an intake and a discharge port, and fitted for sending a fluid flow entering from the intake and outflowing from the discharge port under a second/different thermodynamic state and a second fuel index different from the first fuel index by at least 0.1. This constitution produces a possibility of mixing two flows of outflowing from the outlet and the discharge port, at least, a part of the fuel is mixed with at least a part of the fluid near the outlet and the discharge port, and the second pipe line produces the diluted fuel flow having an intermediate fuel index.
