Abstract: A transportable filling station for pressurized fluids comprises a container which can be placed on the ground. The container has a pressurized-fluid dispenser which can be connected to a pressurized fluid supply via fluid circuit components. The container includes a first support structure parallel to its rear side and a second support structure parallel to its front side. The support structures form a passage between them through which ambient air can flow freely via openings in the lateral sides of the container. At least one of the two support structures supports, facing the passage, the fluid circuit components and the second support structure supports, facing away from the passage, the dispenser.

Abstract: In a two-stage concept for supercharging of internal combustion engines, in which the first stage is performed by an exhaust-gas turbocharger and the second stage by an electrically driven compressor, the compressor is also used to provide the secondary air used for the heating of a catalytic converter. In this manner, the catalytic converter quickly reaches an efficient operating temperature.

Abstract: A invention at least relates to a method for determining the load on an internal combustion engine of a vehicle, operating parameters of the internal combustion engine being recorded and at least one value representing the load is read from a characteristic diagram as a function of the operating parameters recorded, and for at least one further parameter, which is recorded by a sensor already present in the vehicle and which is not an operating parameter of the internal combustion engine, being taken into account in the determination of the load.

Abstract: A system and method for aligning the beam path of a beam-emitting sensor arranged on a motor vehicle. Convenient and nevertheless highly precise setting of the beam direction of the beam-emitting element is possible if, when the vehicle is stationary, an external aligning beam propagating along or parallel to an actual direction of travel of the motor vehicle 1 hits a strictly planar surface on the sensor which reflects the aligning beam, the incident aligning beam and the reflected aligning beam are made to overlap as a result of the position of the sensor being changed.
