The present invention relates to a urea injection nozzle comprising: a main body having a space inside, and formed to supply urea to the space from the outside; a guide part installed in the bottom of the space while a lower part is opened, and having a supply hole along a lateral side; and an injection part penetrated and formed in the lower part of the main body, and installed to spray urea flowing in the supply hole to an exhaust pipe. The present invention has an effect of minimizing a spray droplet size by spraying a urea solution to the exhaust pipe at high pressure through the urea injection nozzle to selectively remove nitrogen oxide (NOx) contained in exhaust gas. Moreover, the present invention has an effect of spraying the urea to the exhaust pipe at high pressure by spraying the urea at high pressure to the injection part of the urea injection nozzle in a swell method. |
