    摘要： A system includes an injector control module and an SCR optimization module. The injector control module controls an amount of ammonia (NH3) stored in a selective catalytic reduction (SCR) catalyst to maintain a first storage level. The SCR optimization module determines whether the first storage level maximizes a conversion efficiency of the SCR catalyst at a first temperature and minimizes a probability of NH3 slip when the temperature of the SCR catalyst transitions from the first temperature to a second temperature. The injector control module controls the amount of NH3 stored in the SCR catalyst to maintain a second storage level when the second storage level maximizes the efficiency of the SCR catalyst relative to the first storage level and minimizes the probability of NH3 slip relative to the first storage level.

    摘要： An exhaust gas treatment device for a diesel engine capable of starting the generation of a combustible gas is provided. The device includes a combustible gas generator. A core member is fitted in the center portion of an annular wall to form an air-fuel mixing chamber between the inner peripheral surface of the annular wall and the outer peripheral surface of the core member. An air-fuel mixture gas in the air-fuel mixing chamber is adapted to be supplied from the end of the air-fuel mixing chamber to a combustible gas generating catalyst to a portion near the center thereof. A heater is used as the core member. The heat dissipating outer peripheral surface of the heater is exposed to the air-fuel mixing chamber. Heat is dissipated directly from the heat dissipating outer peripheral surface of the heater to the air-fuel mixing chamber when starting the generation of the combustible gas.
