Title: Michael Hoffmann: Innovator in Exhaust Gas Purification Technologies
Introduction
Michael Hoffmann is a notable inventor based in Aschaffenburg, Germany. He has made significant contributions to the field of exhaust gas purification, particularly in the development of methods for managing nitrogen oxides and particulates in internal combustion engines. With a total of 2 patents, Hoffmann's work is pivotal in enhancing the efficiency and environmental performance of combustion engines.
Latest Patents
Hoffmann's latest patents include a method for desulfating a nitrogen oxide storage catalyst. This invention relates to a technique that initiates desulfation by increasing the catalyst's temperature to trigger thermal desorption of stored nitrogen oxides. The method cleverly uses the onset of thermal desorption as a signal to enrich the air/fuel mixture, facilitating effective desulfation.
Another significant patent involves a method for removing nitrogen oxides and particulates from the lean exhaust gas of an internal combustion engine. This method addresses the challenge of low concentrations of sulfur oxides in the exhaust stream. The process involves passing the exhaust gas over a nitrogen oxide storage catalyst and a particulate filter, where nitrogen oxides and sulfur oxides are adsorbed under lean conditions. The periodic denitration of the storage catalyst and the desulfurization process are key features of this innovative approach.
