  • Publication number: 20150113963
    Abstract: A method is disclosed for controlling regeneration in a diesel engine after-treatment system having a diesel oxidation catalyst (DOC) and a diesel particulate filter (DPF). The method includes injecting an amount of fuel into an exhaust gas flow upstream of the DOC to superheat the gas flow and assessing a rate of the warm-up of the DOC. The method also includes determining, in response to the assessed rate of the warm-up of the DOC, an amount of catalyst substance available in the DOC for catalyzing the exhaust gas flow. The method additionally includes reducing the amount of fuel injected into the DOC such that the determined available amount of catalyst substance is utilized in the DOC for catalyzing the exhaust gas flow and a predetermined amount of fuel is permitted to slip through the DOC to maintain regeneration temperature in the DPF. A system and a vehicle are also disclosed.

  • Patent number: 8980181
    Abstract: An ammonia generating and delivery apparatus generating ammonia by heating a precursor material with a heating device controlled by a temperature pulse controller which receives commands from a pressure controller, and delivering ammonia with a flow rate controlled by a three-stage PWM controller. The temperature pulse controller is used in a first feedback loop to create a temperature pulse sequence at a surface of the heating device. A pressure controller in a second feedback loop provides duty-cycle commands to the temperature pulse controller, while in delivering ammonia, effects of pressure variation to delivery accuracy are compensated in the three-stage PWM controller, which includes a flow-rate feedback loop. The ammonia generating and delivery apparatus can also include two containers, in which the precursor material in one container is charged and discharged according to the capability of the other container in generating ammonia.
