Title: Jens Drückhammer: Innovator in NOx Storage Converter Technology

Introduction

Jens Drückhammer is a notable inventor based in Braunschweig, Germany. He has made significant contributions to the field of automotive technology, particularly in the area of NOx storage converters. With a total of 2 patents to his name, Drückhammer's work focuses on improving the efficiency and monitoring of catalytic converters in internal combustion engines.

Latest Patents

Drückhammer's latest patents include a method for controlling the regeneration of an NOx storage converter. This innovative method involves measuring the NO concentration in exhaust gas downstream of the NO storage converter. By determining the operating state of the converter, particularly when it switches from absorption mode to regeneration mode, characteristic features of the NO desorption peak are ascertained and compared to predetermined test patterns. This comparison results in a converter-state signal that characterizes the operating state of the NO converter.

Another significant patent is an apparatus and method for monitoring NOx storage catalytic converters. This invention provides a way to monitor the operation of a NO storage catalytic converter in the exhaust stream of an internal combustion engine. The NO content of the gas stream is measured both upstream and downstream of the catalytic converter to determine storage efficiency. If the storage efficiency does not meet a threshold value, a regeneration process is initiated. After regeneration, the storage value is measured to assess whether the catalytic converter is faulty.
