Ludwig Gauckler is a notable inventor based in Schaffhausen, Switzerland. He has made significant contributions to the field of diesel engine exhaust filtration, holding a total of six patents. His innovative approaches have led to advancements in reducing soot combustion temperatures, thereby improving the efficiency of diesel engines.

Latest Patents

Gauckler's latest patents include a filter designed for cleaning exhaust gases of diesel engines. This filter operates by burning deposited soot particles at temperatures ranging from 550 to 700 degrees Celsius. The unique design utilizes open-pore ceramic foam, which is manufactured by coating a burnable open-pore body with a ceramic powder suspension. This process involves burning out the substrate material at temperatures between 100 and 500 degrees Celsius, followed by sintering at elevated temperatures. The resulting filters possess a self-supporting ceramic structure with an internal surface area of 1 m²/l to 10 m²/l and an open porosity of 55-92%. Notably, these innovations have reduced the soot combustion temperature to between 400 and 550 degrees Celsius, and when coated with catalytically active substances, it can be lowered to 350 degrees Celsius.

Another significant patent focuses on filters for cleaning exhaust gases from diesel engines, which also utilize open-pored foam ceramic bodies. In this design, the deposited soot particles are burned at temperatures between 550 and 700 degrees Celsius at periodic intervals. To enhance performance, the ceramic bodies are catalytically coated, and the region of the foam ceramic body that first encounters the exhaust gases has a denser pore structure. This design helps lower the inflammation temperature of the soot during the filter's regeneration phase, effectively managing temperature peaks that can lead to soot ignition.
