Audi AG ) is a German automobile manufacturer that designs, engineers, produces, markets and distributes luxury automobiles. Audi oversees worldwide operations from its headquarters in Ingolstadt, Bavaria, Germany. Audi-branded vehicles are produced in nine production facilities worldwide.Audi has been a majority owned subsidiary of Volkswagen Group since 1966, following a phased purchase of Audi AG's predecessor, Auto Union, from Daimler-Benz. Volkswagen relaunched the Audi brand with the 1965 introduction of the Audi F103 series.The company name is based on the Latin translation of the surname of the founder, August Horch. "Horch", meaning "listen" in German, becomes "audi" in Latin. The four rings of the Audi logo each represent one of four car companies that banded together to create Audi's predecessor company, Auto Union. Audi's slogan is Vorsprung durch Technik, meaning "Advantage through Technology". However, since 2007 Audi USA has used the slogan "Truth in Engineering". Audi is a member of the "German Big 3" luxury automakers, along with BMW and Mercedes-Benz, which are the three best-selling luxury automakers in the world. Wikipedia.

The invention relates to an electromagnet for a hydraulic system, in particular for an automatic transmission of a motor vehicle, having an armature space, which can be flow-connected to hydraulic lines of the hydraulic system, is filled with hydraulic medium, and in which an armature (11) is mounted in a stroke-adjustable manner (h2), said armature having a shut-off body and dividing the armature space into an aperture-side chamber (37), which faces the flow aperture, and an inner chamber (39), which faces away therefrom, an oil exchange taking place during a stroke movement of the armature, during which a displacement volume of the hydraulic medium flows from the aperture-side chamber into the inner chamber. According to the invention, a hydraulic line (47, 53, 55) that leads to the aperture-side chamber or to the inner chamber of the armature space has at least one dirt collection element, which is preferably formed as a permanent magnet and retains impurities in the hydraulic medium that flows through the hydraulic line during oil exchange.

Hydrogen Mobility Europe 2 (H2ME 2) brings together action in 8 European countries to address the innovations required to make the hydrogen mobility sector truly ready for market. The project will perform a large-scale market test of hydrogen refuelling infrastructure, passenger and commercial fuel cell electric vehicles operated in real-world customer applications and demonstrate the system benefits generated by using electrolytic hydrogen solutions in grid operations. H2ME 2 will increase the participation of European manufacturers into the hydrogen sector, and demonstrate new vehicles across a range of platforms, with increased choice: new cars (Honda, and Daimler), new vans (range extended vehicles from Renault/Symbio and Renault/Nissan/Intelligent Energy) and a new medium sized urban delivery truck (Renault Trucks/Symbio). H2ME 2 develops an attractive proposition around range extended vehicles and supports a major roll-out of 1,000 of these vehicles to customers in France, Germany, Scandinavia and the UK. 1,230 new hydrogen fuelled vehicles will be deployed in total, trebling the existing fuel cell fleet in Europe. H2ME 2 will establish the conditions under which electrolytic refuelling stations can play a beneficial role in the energy system, and demonstrate the acquisition of real revenues from provision of energy services for aggregated electrolyser-HRS systems at a MW scale in both the UK and France. This has the further implication of demonstrating viable opportunities for reducing the cost of hydrogen at the nozzle by providing valuable energy services without disrupting refuelling operations. H2ME 2 will test 20 new HRS rigorously at high level of utilisation using the large vehicle deployment. The loading of stations by the end of the project is expected to average 20% of their daily fuelling capacity, with some stations exceeding 50% or more. This will test the HRS to a much greater extent than has been the case in previous projects.
