Latest Patents

Among his recent patents, two significant inventions stand out. The first is a "Method for operating an exhaust gas purification system of a motor vehicle combustion engine." This method employs an SCR (Selective Catalytic Reduction) catalyst, where a reducing agent containing ammonia is metered into the exhaust gas. This process uses a predetermined metering rate, which is adjusted based on a base value and an adaptation factor. The innovation includes a testing procedure that checks and refines the adaptation factor by comparing nitrogen oxide values taken from a sensor located downstream of the SCR catalyst.

The second notable patent is an "Exhaust gas aftertreatment installation and method." This invention utilizes a nitrogen oxide storage catalytic converter paired with an SCR catalytic converter, incorporating a particulate filter. The regeneration phases of the nitrogen oxide storage catalytic converter are calculated based on the nitrogen oxide content in the exhaust gas, ensuring optimized performance and ammonia generation for effective treatment. This technology is particularly applicable to motor vehicle internal combustion engines that predominantly operate in lean-burn modes.
