  • Publication number: 20230193803
    Abstract: A method for controlling the operation of an exhaust aftertreatment system (EATS) in a vehicle is described. The EATS comprises a main SCR catalyst and a pre-SCR catalyst, a pre-injector arranged upstream the pre-SCR catalyst for providing reductant, a bypass channel fluidly connected to the fluid channel and arranged to bypass the pre-SCR-catalyst and the pre-injector, and a valve configured to control a split of exhaust gases between the pre-SCR catalyst and the bypass channel. The method includes determining the amount of ammonia stored in the pre-SCR catalyst; determining the temperature of the main SCR catalyst; when the ammonia storage in the pre-SCR catalyst is below an ammonia storage threshold and the temperature of the main SCR catalyst is above a temperature threshold, injecting reductant by the pre-injector and controlling the valve to allow a flow of exhaust gases to the pre-SCR catalyst sufficient for transporting the injected reductant to the pre-SCR catalyst for increasing the ammonia storage.

  • Publication number: 20160009531
    Abstract: A system or method, for controlling at least two automated non-passing rail mounted gantry cranes, has, for each crane, a crane control unit for ensuring execution of at least one work order received by the respective crane from an external scheduling system, and may have a rescheduling unit which performs a rescheduling of the at least one work order based on an expected trajectory along the rail determined for each work order. The rescheduling can be achieved by splitting at least one of the work orders into at least two new work orders and by re-sequencing and re-allocating resulting work orders to reduce the number or duration of situations, where the expected trajectory of one crane blocks the expected trajectory of another crane and/or to reduce a workload imbalance between the cranes. The rescheduling unit operates in parallel with the crane control units, and dynamically updates these original work orders.

  • Patent number: 8499556
    Abstract: A diesel engine system and a method for operating said system are provided. The diesel engine system includes a diesel engine provided with an exhaust conduit including a controllable supercharger located upstream of a catalytic converter, a fuel injector located between the supercharger and the catalytic converter, a diesel particulate filter located downstream of the catalytic converter, and a control unit for controlling the engine system. The control unit is arranged to determine that a regeneration of the particulate filter is required, which regeneration is initiated when a predetermined condition is fulfilled. The fuel injector is arranged to inject a predetermined amount of fuel during a first stage of the regeneration, and the supercharger is arranged to vary the flow rate of exhaust during the injection of fuel. The catalytic converter is arranged to combust the injected fuel, and the combusted fuel is arranged to burn particulates trapped within the diesel particulate filter.
