温度の過剰な温度上昇をまねく。According to the prior art, it is considered that a higher denitration reaction temperature is better in order to obtain a high denitration rate by SCR. Therefore, the SCR 3 is installed between the exhaust gas cylinder outlet collecting pipe 2 having a relatively high temperature and the supercharger 4 inlet. However, the heat capacity of the SCR 3 is large, and the follow-up of the supercharger 4 is delayed even when the load of the diesel engine is reduced, and the turbocharger rotation speed (RT / C) corresponding to the load is reduced. Be late. As a result, excessive combustion air is supplied to the diesel engine, resulting in an excessive decrease in the engine exhaust gas temperature (T E ).
Also, the energy supplied to the supercharger 4 is greatly reduced,
Excessive reduction of the turbocharger rotation speed leads to excessive temperature rise of the excessive exhaust gas temperature at the engine outlet.
