coinventor Phạm Duy Tùng

Phạm Duy Tùng, a graduate of Ho Chi Minh City University of Technology and Education, was perhaps the most influential figure in convincing the patent holder to keep the project rooted in Vietnam. Despite his youth, Tùng brought years of hands‑on experience with automotive and motorcycle engines—skills honed from his family’s vehicles and a lifelong passion for mechanics.  

In 2013, a patent was filed for an improvement in the rod‑guide system. To test this and other innovations, Tùng helped design, build, and evaluate a one‑off prototype. The results of those trials became foundational to the current patents and final design.

Tung's innovative contributions were born from his University training coupled with his hands-on work experience. His insights helped the team avoid costly mistakes during development. Without Tung's dedication and hard work, there would be no Kamtech OBE 1.
