Provided is a process that may comprise cooling an engine exhaust emissions comprising SO.sub.x on a vehicle that may come from an engine. The cooled engine exhaust emissions comprising SO.sub.x may be passed to one or more absorption units. The SO.sub.x may be extracted from the engine exhaust emissions with a sorbent supported on solid porous media in an absorption unit on the vehicle to form an absorbed SO.sub.x. The absorbed SO.sub.x may be desorbed, followed by forming one or more SO.sub.x product from the desorbed SO.sub.x. The one or more SO.sub.x product may be unloaded to an off-vehicle facility.

A control system includes a sensor configured to detect information associated with an area surrounding a vehicle and an electronic control unit configured to control an automated driving of the vehicle. The electronic control unit includes a driving plan generation unit, a driving control unit, a regeneration control unit configured to control a process for regenerating an engine exhaust gas treatment apparatus, and a lane selection unit configured to predict an engine load associated with traveling in each lane of a plurality of lanes. The lane selection unit is also configured to select a lane which would cause an increase in engine load when the control for regenerating the exhaust gas treatment apparatus is being performed by the regeneration control unit. The control system is configured to cause the vehicle to be driven in the lane selected by the lane selection unit.

A method for regulation of an internal combustion engine with an SCR catalytic converter in which the operating point of the engine is predefined by an engine control unit and the operating point of the catalytic converter is predefined by an SCR control unit. An overall system quality measure is calculated by an optimizer in accordance with fed back values of the engine control unit and fed back values of the SCR control unit, by changing the default values for the engine control unit and the SCR control unit, the optimizer minimizes the overall system quality measure for a prediction horizon regarding operating costs. On the basis of the minimized overall system quality measure the optimizer sets the default values for the engine control unit and the default values for the SCR control unit as decisive for setting the operating point of the engine and the catalytic converter.

An exhaust purification system includes: an NOx reduction type catalyst; an MAF sensor; an SOx purge control unit that uses an air system control having an intake air amount feedback-controlled based on a target intake air amount and an injection system control for a target injection increase amount set based on the target intake air amount, and a fuel injection amount feedback-controlled based on the target injection increase amount; an SOx purge prohibition processing unit that prohibits an SOx purge control; and a warming mode control unit that open-loop controls an air system when the SOx purge control is prohibited, controls the fuel injection amount, and maintains the exhaust gas at a temperature. The SOx purge control unit executes the injection system control by switching the target intake air amount into an actual intake air amount when starting the SOx purge control after a warming mode control is ended.
