Title: Dirk Herbstritt: Innovator in Exhaust-Gas Aftertreatment Systems

Introduction

Dirk Herbstritt is a notable inventor based in Durmersheim, Germany. He has made significant contributions to the field of exhaust-gas aftertreatment systems, holding a total of 3 patents. His work focuses on improving the efficiency and effectiveness of these systems in motor vehicles.

Latest Patents

One of his latest patents is an operating and diagnostic method for an SCR exhaust-gas aftertreatment system. This method involves measuring signals from an exhaust gas sensor sensitive to nitrogen oxide and ammonia, which is positioned downstream of the SCR catalytic converter. In normal operating mode, ammonia is supplied to the SCR catalytic converter based on a filling level model, ensuring that the ammonia filling level is maintained at a predefined nominal value. If the exhaust gas sensor signal exceeds a certain limit, the urea dosing rate is increased, allowing for a return to normal operation or a switch to a diagnostic mode based on the sensor's signal profile.

Another significant patent is a method and apparatus for detecting the presence of a prescribed heat exchanger in a motor vehicle. This method observes the temperature of a heat-exchanger medium along with other operational parameters over a specified time window. By detecting the expected and current temperature gradients, the presence of the heat exchanger can be confirmed.
