Abstract (en)

This invention relates to a fuel discharge member which can reduce the amount of NOx exhaust. The fuel discharge member is fixed on a fuel supply conduit (17), and comprises: a main body (23) having an internal space (22) which communicates with a fuel passage in the fuel supply conduit, fuel discharge outlets (21) which communicate with the internal space, and a trailing edge (23a). The thickness (t) of the trailing edge is no more than 5mm, or a flow passage block ratio of the fuel discharge member is no more than 10% with respect to the cross-sectional area of the air flow passage in which the fuel discharge member is to be placed. Alternatively, the main body is a flat tube.
