Prof. Huynh Thanh Cong 

In 2014, Professor Cong was teaching at the University of Science and Technology in District 10, Ho Chi Minh City, when he was first contacted by Jim Duncalf and Tung Pham. At that time, the company sponsoring the development and commercialization of the Rad Cam engine at their Ho Chi Minh plant lacked the talent, skills, and resources to carry the project forward, and at the time IC engine development was getting negative political pressure in Jim Duncalf's home country, the US. 

It was Professor Cong’s deep understanding, insight, and encouragement that convinced Jim to keep the Rad Cam project in Vietnam rather than relocating it elsewhere. Professor Cong is a recognized authority in fuel injection and compression combustion, with several published papers on internal combustion engines of various types. Over the years his expertise, and support has provided critical guidance in overcoming multiple engineering challenges, including resolving specialized material issues during the building and testing of the material prototype.  

However, his most inspiring contribution was his observation of the similarity between the Rad Cam’s constant acceleration dynamics and the natural piston behavior in Free Piston Engines (FPE), where inertial forces dictate motion. In 2025, he authored a paper on how FPE dynamics could enhance the efficiency of two-stroke HCCI engines, and he even built and tested a prototype to validate his ideas. 

Through his technical acumen and steadfast support, Professor Cong helped solidify Vietnam’s role in the Rad Cam journey. His contributions remain embedded in Kamtech’s commitment to innovation, persistence, and the pursuit of engineering excellence.
