Title: Gerd Rosel: Innovator in Exhaust Gas Purification Technologies
Introduction
Gerd Rosel is a notable inventor based in Dresden, Germany. He has made significant contributions to the field of exhaust gas purification systems, holding a total of 3 patents. His work focuses on innovative methods and devices that enhance the efficiency and accuracy of exhaust gas diagnostics.
Latest Patents
One of Gerd Rosel's latest patents is a method and device for diagnosing an exhaust gas cleaning system. This invention is distinguished by its ability to diagnose an individual catalytic converter of an exhaust gas purification unit assigned to an internal combustion engine in a Y configuration. This is achieved despite the absence of an exhaust gas probe between the individual catalytic converter and the main catalytic converter. The diagnosis is based on signals from the exhaust gas probes belonging to the exhaust gas purification unit, allowing for the determination of the oxygen storage capacity of the individual catalytic converter.
Another significant patent is a process for model-assisted determination of the fresh-air mass flowing into a cylinder. This method utilizes an inlet pipe flow model, described by a nonlinear differential equation. The model approach includes the modeling of an external exhaust-gas recycling system, variable inlet systems, and systems with variable control valves. This model-assisted load detection method can be applied in engine control systems based on air mass flow and inlet pipe pressure. A correction algorithm in the form of a model control loop allows for continuous improvement of accuracy, even when model parameters are inexact.
