  • Patent number: 10392997
    Abstract: The present disclosure provides a method for operating an exhaust gas aftertreatment device for cleaning an exhaust gas flow of a motor vehicle with an internal combustion engine operated in normal mode with oxygen surplus. An oxygen store arranged downstream of an NOx storage catalyst of the exhaust gas aftertreatment device receives oxygen in normal mode, and during a regeneration mode emits oxygen for converting breakthrough hydrocarbons and/or carbon monoxide. The oxygen store is assigned to a particulate filter and/or an oxidation catalyst of the exhaust gas aftertreatment device. The particulate filter and/or the oxidation catalyst is arranged downstream of the NOx storage catalyst.

  • Patent number: 10040454
    Abstract: A method is provided for controlling a NOx storage catalytic converter that is disposed in the exhaust system of an internal combustion engine of a motor vehicle with an adaptive cruise control system, wherein regeneration of the NOx storage catalytic converter is started depending on the distance to a vehicle ahead. For this the motor vehicle is accelerated in a rich mode for regeneration if the distance to the vehicle ahead is large enough so that the regeneration will be completed during an acceleration phase in which the distance is reduced.

  • Patent number: 10029671
    Abstract: An operating method for a motor vehicle having a hybrid drivetrain includes, during a demand check, comparing at least one value which characterizes a current state of an exhaust-gas after-treatment device, with a setpoint value of the exhaust-gas after-treatment device. In response to the comparison indicating a deviation of the value characterizing the current state of the exhaust-gas after-treatment device from the setpoint value, a demand for a measure is indicated. The measure includes supplying charge gas, which includes recirculated exhaust gas, to the internal combustion engine during overrun operation. In addition, a capability check is carried out to detect conditions suitable for implementing the operating method.

    Abstract: The present disclosure relates to an operating method for a motor vehicle having a hybrid drivetrain where in a demand check, at least one exhaust-gas after-treatment actual value, which characterizes a current exhaust-gas after-treatment actual state, is compared with an exhaust-gas after-treatment setpoint value, and if, in the event of a deviation of the exhaust-gas after-treatment actual value from the exhaust-gas after-treatment setpoint value, a demand for a measure is detected. The measure comprises supplying charge gas, which has recirculated exhaust gas, to the internal combustion engine during overrun operation. Also a capability check is carried out to detect conditions suitable for implementing the operating method.

  • Patent number: 9016046
    Abstract: A method, comprising purging a storage catalytic converter of stored NOx by diverting only a portion of incoming exhaust flow around the catalytic device while increasing injection of reductant to the storage catalytic converter; and responsive to the diverting, adjusting injection of an ammonia-containing fluid into recombined exhaust flow upstream of an SCR catalytic converter. Bypass of the storage catalytic converter reduces available oxygen and air flow through the storage catalytic converter, providing a more advantageous environment for reduction of NOx in the storage catalytic converter.

  • Patent number: 8820050
    Abstract: Embodiments for reducing ammonia slip are provided. In one example, a method for reduction of ammonia emissions from an engine exhaust gas aftertreatment device with an SCR catalyst comprises determining a concentration of NOx and/or ammonia in the exhaust gas aftertreatment device, comparing a determined value of NOx and/or ammonia concentration with a nominal value for NOx and ammonia, respectively, and if an actual or shortly forecasted ammonia concentration is above the respective nominal value, triggering engine conditions with higher exhaust NOx concentration. In this way, ammonia slip may be reduced without degrading fuel economy.
