German Audi Automobile Company's New Fuel Laboratory Successfully Synthesized 'e Diesel'
Reprinted from Science and Technology Daily. On May 4, the new fuel laboratory of German Audi Automobile Company cooperated with Sunfire, a new energy company in Dresden, and recently successfully developed a process for producing diesel using carbon dioxide and water. This new process for synthetic diesel is expected to be used in atmospheric protection and resource utilization. open up a whole new way. It is reported that this is called“e diesel”The basic principle of the project is to use electricity to convert into liquid fuel (PtL), the raw materials are carbon dioxide and water. The production steps are very simple: first, the water is evaporated in the boiler, and the water is electrolyzed into hydrogen and oxygen at a high temperature of 800 degrees Celsius. This is an ordinary water electrolysis technology. The electricity used in the electrolysis process is the surplus ecological electricity during the low-peak period of the power grid. ; The second step is to synthesize the hydrogen and carbon dioxide obtained by electrolysis at high temperature and high pressure to generate long-chain liquid hydrocarbons, which are called“Blue Crude”The hydrocarbons have an energy conversion efficiency of 70%, which is no less than the energy conversion efficiency of fossil fuels, and does not contain sulfur and aromatic hydrocarbon impurities, and has a high cetane number (indicating the spontaneous combustion index of diesel fuel when it is burned in a diesel engine). , low ignition point and other characteristics. It is understood that in the project laboratory in Dresden, 160 liters of synthetic diesel can be made per day using this new process. Although the current output is still very small, if industrial production can be realized, the future application prospects are immeasurable . According to project leader Mangold, Audi's“e fuel”An important addition to electric vehicles, the use of carbon dioxide as a fuel is not only an innovation for the automotive industry, but can also be applied in other fields. According to reports, the German Federal Ministry of Education and Research has given support to this project. Minister of Education and Research Wanka said that if the project is successful,“CO2 can then be used as a feedstock, which will make a decisive contribution to atmospheric protection, resource efficiency, and the path to a green economy”.

Cut resistance is one of the most critical performance indicators in personal protective equipment (PPE) testing, directly affecting worker safety in high-risk industries such as metal processing, machinery manufacturing, and emergency rescue. The TDM Cut Test Machine GT-KC28 plays a vital role in accurately evaluating the cut resistance of PPE products, including gloves, protective clothing, footwear materials, composite materials, rubber, and industrial textiles.
By adopting high-precision force control systems, intelligent data processing, and stable transmission technology, the GT-KC28 TDM Cut Tester can accurately measure the critical cutting force of materials and ensure excellent repeatability and comparability of test results. Its user-friendly touch-screen operation, comprehensive data storage, USB data export, and built-in thermal printer greatly improve laboratory efficiency and data traceability.
The TDM Cut Test Machine GT-KC28 fully complies with major international and national standards such as ISO 13997, EN 388, ASTM F2992/F2992M, ANSI/ISEA 105, and GB 24541-2022, making it a reliable solution for PPE manufacturers, third-party testing laboratories, and research institutions. Through precise and standardized cut resistance testing, the GT-KC28 helps reduce industrial cutting injuries, supports PPE certification across global markets, and ensures that protective equipment delivers reliable safety performance in real-world applications.
Safety gloves are critical personal protective equipment (PPE) used in industries such as manufacturing, welding, construction, firefighting and chemical processing. To ensure reliable protection, gloves must undergo strict performance testing before entering the market.
Professional gloves testing equipment helps manufacturers evaluate important properties including cut resistance, thermal protection, contact heat resistance, tensile strength and impact protection. By selecting suitable testing machines, companies can improve product quality, meet international standards and reduce safety risks.
This complete buying guide introduces the main types of glove testing equipment, explains their applications and provides practical advice on choosing the right solution for your laboratory or production requirements.
