The disclosure relates to an electrically powered mobile fluid supply system (MFSS) for supplying fluid to a host unit. The MFSS comprises at least one pressurized fluid volume, a fluid dispenser fluidly connectable to the host unit and configured to supply fluid from the at least one pressurized fluid volume to the host unit in a fluid supply operation, and at least one compressor configured to build sufficient pressure for the fluid supply operation in the MFSS. The MFSS is configured to be electrically connected to the host unit and the at least one compressor is configured to be electrically connected to the MFSS and electrically powered by the host unit during the fluid supply operation. The disclosure further relates to a method for supplying fluid to a host unit, to a control unit configured to control the fluid supply operation, and to the MFSS.

The present disclosure relates to a method for determining urea feeding in an exhaust gas aftertreatment system (), the exhaust gas aftertreatment system () being connectable to an internal combustion engine () operating under an engine operating condition, the system () comprising a first Selective Catalytic Reduction (SCR1) system comprising a first selective reduction catalyst (SCR1c) and a first doser () configured for feeding urea upstream the SCR1 system, at least one Particulate Filter (PF) downstream the SCR1 system or as a substrate for the SCR1c and a second Selective Catalytic Reduction (SCR2) system downstream the PF, the SCR2 system comprising a second selective reduction catalyst (SCR2c) and a second doser () configured for feeding urea upstream the SCR2c, the method comprising the steps of estimating the amount of particles in the PF; and determining the amount of urea to be fed by the respective first and second doser () based on the engine operating condition and such that: a) the amount of particles in the PF is within a predefined particle amount range, and, b) the NOx level of the exhaust gas exiting the SCR2 system is within a predetermined NOx level range. The present disclosure also relates to an exhaust gas aftertreatment system () and a vehicle comprising the exhaust gas aftertreatment system (), a computer program comprising program code means for performing the steps of the method, a computer readable medium carrying a computer program comprising program code means for performing the steps of the method and a control unit for controlling urea feeding in the exhaust gas aftertreatment system ().

An air-bag for use in a safety arrangement in a motor vehicle includes a front panel and a rear panel. The two panels are superimposed and attached to one another around their peripheries in order to define an inflatable chamber. The front panel is provided with an aperture within which is secured an additional panel. The additional panel has an area greater than the aperture and is configured so as to define a plurality of adjacent substantially wave-shaped projections which extend forwardly from the front panel when the air-bag is inflated.
