Title: Rudi Drefs and His Patent for Internal Combustion Engine Operation
Introduction
Rudi Drefs is an inventor associated with Friolzheim, Germany, and Robert Bosch. His work includes a patented method and device for operating an internal combustion engine with an exhaust-gas treatment system.
Latest Patents
Drefs is credited with 1 patent: “Method for Operating an Internal Combustion Engine and Device for Implementing the Method.” The invention monitors reagent pressure between a safety valve and a dosing valve positioned directly in the engine’s exhaust-gas region. Pressure readings are taken under different valve states and compared with a threshold. If the threshold is exceeded, the system provides a fault signal. This approach is intended to improve safety, particularly when fuel is used as the reagent.
Career Highlights
Drefs’s patent addresses the monitoring and safe delivery of reagents used in exhaust-gas treatment. The disclosed method combines pressure measurement with threshold-based fault detection.
Collaborations
The information provided associates Drefs with Robert Bosch and identifies Andreas Pfaeffle and Cord Scharsack as coworkers.
Conclusion
Rudi Drefs’s patent focuses on detecting reagent-pressure faults in internal combustion engine exhaust-treatment systems, with safety as a central consideration.
