Title: Walter Viess: Innovator in Exhaust-Gas Recirculation Systems

Introduction

Walter Viess is a notable inventor based in Schwieberdingen, Germany. He has made significant contributions to the field of internal combustion engines, holding a total of 9 patents. His work focuses on improving the efficiency and functionality of exhaust-gas recirculation systems.

Latest Patents

One of Walter Viess's latest patents is an innovative exhaust-gas recirculation system for internal combustion engines. This system includes diagnostic means based on temperature values measured in the exhaust-gas return duct under specific conditions. A differential value between the actual temperature in the exhaust-gas return duct and a reference temperature is provided for a flow-through test. This differential value is then processed through a low-pass filter. If the conditions for diagnosis are met, the system determines whether the recirculation system is functioning correctly by comparing the differential value to a threshold value. Additionally, a leak test of the exhaust-gas return valve can be performed based on the differential value of the two temperatures. Another patent involves a method for recognizing the power stroke of a cylinder in an internal combustion engine.
