Prof. Huynh Thanh Cong: Guiding Vision in Vietnam 

In 2016, while teaching at the University of Science and Technology in District 10, Ho Chi Minh City, Professor Cong was first approached by Jim Duncalf and Phạm Duy Tùng. At the time, the company sponsoring Rad Cam development in Vietnam lacked the technical resources to advance the project, while in the United States, research into petrol engines was under increasing political pressure as government funding shifted heavily toward electric vehicles.
It was Professor Cong’s insight and encouragement that convinced Jim to keep the Rad Cam project rooted in Vietnam rather than relocating elsewhere. A recognized authority in fuel injection and compression combustion, with several published papers on internal combustion engines, Cong provided essential guidance in overcoming engineering hurdles—including resolving specialized material challenges during prototype testing.
Perhaps his most inspiring contribution was recognizing the similarity between the Rad Cam’s constant‑acceleration dynamics and the natural piston behavior in Free Piston Engines (FPE), where inertial forces govern motion. Building on this observation, he authored a 2025 paper on how FPE dynamics could enhance the efficiency of two‑stroke HCCI engines, and even constructed and tested a prototype to validate the concept.
Through his technical expertise and steadfast support, Professor Cong helped secure Vietnam’s role in the Rad Cam journey. His contributions remain embedded in Kamtech’s commitment to innovation, persistence, and engineering excellence.
