ABSTRACT:
The present invention relates to a structure of a liquid reducing agent injection nozzle in an exhaust emission purifying system arranged to inject and supply a liquid reducing agent into an exhaust flow passage so as to reduce and purify NOx in exhaust gas. A nozzle tip end portion of the liquid reducing agent injection nozzle which protrudes from a wall surface of an exhaust flow passage into the passage, is bent obliquely with respect to an exhaust flow direction, or nozzle holes of the nozzle tip end portion are formed so as to tilt in the exhaust flow direction with respect to a radial direction perpendicular to a center axis of the nozzle tip end portion or are unevenly distributed in the circumferential direction of the nozzle tip end portion.
