TL;DR: In this paper, a reducer is supplied into the exhaust gases by the injection valve, and a cooling medium is circulated through the cooling chamber to cool the injector, and nitrogen oxides are removed from the exhaust gas by reducing/reacting the nitrogen oxide with the reducer on a selective reducing catalyst.

TL;DR: In this paper, the authors proposed a method to uniformly disperse urea water in exhaust gas without increasing the pressure loss of the exhaust gas, while preventing the Urea water from being deposited on a wall and then precipitated as solid materials.

TL;DR: In this paper, a denitration catalyst was used to reduce nitrogen oxide in the exhaust gas, where urea water was injected from the injection valve to cover the evaporation tube.

TL;DR: In this paper, the authors proposed a solution to remove NOx in correspondence to a whole operation region extending from a low load region for a low exhaust gas temperature at the time of starting of a diesel engine and a small exhaust gas amount to a high load region of a high exhaustgas temperature and a multi-exhaust gas amount.

TL;DR: In this article, the authors proposed a solution to remove NOx by compact constitution and a low power consumption, in a full operation region extending from a low load region, where an exhaust gas temperature and an exhaustgas amount are low, to a high load region where a high amount of exhaust gas is high.
