Title: Innovations by Johannes Kuenstler

Introduction

Johannes Kuenstler is a notable inventor based in Aachen, Germany. He has made significant contributions to the field of internal combustion engines, holding a total of 6 patents. His work focuses on improving engine efficiency and reducing emissions, which is crucial in today's automotive industry.

Latest Patents

One of his latest patents is a control method for temporarily increasing the exhaust gas temperature. This invention relates to a method that increases the exhaust gas temperature of an internal combustion engine by raising the exhaust back-pressure while maintaining an exhaust gas recirculation rate. Additionally, the fuel injection quantity of a main injection into the engine is increased. This approach allows for a higher exhaust gas temperature and prevents engine oil dilution due to retarded post-injections.

Another significant patent by Kuenstler is a method for controlling the starting of an internal combustion engine. This invention addresses the starting process of an engine coupled to an exhaust aftertreatment device that requires a minimal threshold temperature for proper operation. Within a specific timeframe after starting the engine, the load on an electrical generator driven by the engine is increased. Simultaneously, the air intake is throttled to reduce the intake manifold pressure to a target level. These measures facilitate faster engine and catalyst warm-up, thereby reducing emissions, particularly for diesel engines in conjunction with an oxidation catalyst.
