Title: The Innovative Mind of Charles L. Siewert
Introduction
Charles L. Siewert is a notable inventor based in Madison, WI (US). He is recognized for his contributions to automotive technology, particularly in the area of fuel-air mixing systems. His innovative approach has led to the development of a unique device that enhances engine performance.
Latest Patents
Siewert holds a patent for the Vortex Fuel Air Mixer. This device is strategically positioned between the air throttle and the intake manifold of an engine. The design allows part of the expansion flow velocity past the air throttle to flow tangentially into the vortex chamber of the mixer. This configuration provides angular momentum, driving the flow into a vortical pattern. The flow streamlines within the vortical flow form into a generally irrotational flow pattern, swirling from the outside wall of the vortex chamber inwardly to a central vortex chamber outlet. This outlet feeds the engine intake manifold. Centrifugal forces in the swirling flow fling fuel droplets to the outside wall of the vortex chamber, similar to a cyclone scrubber. The liquid fuel must evaporate to exit the vortex chamber. The interaction of evaporation, flow structure, and turbulence relations inside the vortex chamber produces a homogeneous mixture at the outlet. The device exhibits excellent transient response due to the short fuel evaporation time in the vortex chamber.
