Title: Innovations of Andreas Geisselmann
Introduction
Andreas Geisselmann is a notable inventor based in Offenbach, Germany. He has made significant contributions to the field of exhaust gas aftertreatment systems, holding a total of five patents. His work focuses on improving the efficiency and effectiveness of internal combustion engines through innovative technologies.
Latest Patents
One of his latest patents involves a process that addresses the challenge of supplying nitrogen oxides (NOx) in accordance with requirements. This is achieved through temperature control of a precatalyst that operates independently of the engine's state. The associated apparatus includes a precatalyst containing at least one oxidation component, which can be controlled separately from the engine's operating conditions. Additionally, it features an active selective catalytic reduction (SCR) stage with an SCR catalyst and an upstream metering facility for a reducing agent sourced externally. A particle filter may also be positioned between the precatalyst and the metering facility, with the precatalyst potentially containing nitrogen oxide storage material.
Another significant patent pertains to an exhaust gas post-treatment system for internal combustion engines. This system includes an intake device that introduces hydrocarbons into the exhaust gas pipe, which carries exhaust process gas from the engine. The treatment device downstream increases the exhaust process gas temperature by oxidizing the hydrocarbons. The system is designed to ensure that the catalytic components have a platinum proportion of less than 50% in specific regions of the catalytic coating.
Career Highlights
Throughout his career, Andreas Geisselmann has worked with prominent companies such as Umicore AG & Co. KG and Uhde GmbH. His experience in these organizations has contributed to his expertise in developing advanced technologies for exhaust gas treatment.
