Title: Gary G Gilbertson: Innovator in Exhaust System Design
Introduction
Gary G Gilbertson is a notable inventor based in Fond du Lac, WI (US). He has made significant contributions to the field of exhaust system design, holding a total of 5 patents. His innovative approach has led to advancements that enhance engine performance while maintaining efficiency.
Latest Patents
One of Gilbertson's latest patents is an exhaust system tuned for performance with shared walls. This invention features an exhaust pipe for internal combustion engines that incorporates non-circular passages extending from the engine exhaust port to the atmosphere. The design ensures that the performance of the engine is not compromised by these non-circular passages, which can be compared to traditional pipes with circular passages of the same cross-sectional areas. The unique non-circular cross-section allows for multiple passages to be housed within a single outer wall, with plates dividing the interior into separate passages. This innovative design enables adjacent passages to share a wall, optimizing space and performance. Additionally, the exhaust pipe includes headers that direct exhaust gases from the engine to the associated passages. A modification of this invention allows for tuning the exhaust pipe for performance at two different engine operating speeds by adjusting the tuning of passages on either side of a shared wall.
