Title: Ralf Kaufmann: Innovator in Engine Technology and Vehicle Dynamics
Introduction
Ralf Kaufmann is a notable inventor based in Walldürn, Germany. He has made significant contributions to the fields of internal combustion engine technology and vehicle dynamics. With a total of 4 patents to his name, Kaufmann's work reflects a commitment to innovation and engineering excellence.
Latest Patents
Kaufmann's latest patents include a method and apparatus for venting a crankcase of an internal combustion engine. This innovative method allows for effective venting under varying engine loads. In a first operating range under part-load, the crankcase is vented via a first venting line that opens into the intake line downstream of a throttle valve. In contrast, during full load engine operation, a second venting line is utilized, which opens into the intake line upstream of the throttle valve. This design incorporates a control valve and a central unit that manages the flow of vent gases, preventing them from reaching the engine exhaust system during overrun conditions.
Another significant patent is for a vehicle with an auxiliary rear-wheel steering mechanism. This non-track-bound vehicle features arbitrarily steerable front wheels and an additional rear-wheel steering system. This system can operate automatically or be switched to manual operation, adjusting the rear wheels' steering angle based on the front wheels' angle and other parameters. This innovation enhances maneuverability and minimizes rear swinging during the drive-away mode.
