Title: Won Geun Lee and His Engine-Design Patent
Introduction
Won Geun Lee is an inventor associated with Cedar Falls, Iowa, and Deere & Company. His work includes an internal-combustion-engine design intended to reduce thermal stress on the cylinder head.
Latest Patents
Lee is credited with 1 patent: “Piston and Injector for Reduced Head Thermal Loading.” The patent describes a piston and injector system designed to limit heat concentration on the cylinder head. Its piston has a profiled upper surface forming an annular bowl with a primary configuration and an asymmetric sector. That sector receives fuel spray from the injector and directs combustion to reduce localized heating, helping protect engine durability and performance.
Career Highlights
Lee’s listed patent reflects an engineering focus on managing combustion and heat distribution in internal-combustion engines. The design addresses thermal loading through the coordinated geometry of the piston bowl and the direction of the injector’s fuel spray.
Collaborations
Lee is associated with Deere & Company. His listed coworker is Bryan T. Geisick.
Conclusion
Won Geun Lee’s patent presents a targeted approach to reducing cylinder-head heat concentration through piston and injector design, with the goal of supporting engine durability and performance.
