Tunisian Researcher Faten Mouldi Derouaz Receives US Patent for Revolutionary Hybrid Car Engine
Tunisian Professor at King Fahd University Secures Groundbreaking Invention in Automotive Engineering
Tunisian researcher and professor at King Fahd University, Faten Mouldi Derouaz, has announced the receipt of a US patent for her innovative hybrid car engine, capable of operating on four different energy sources. In an exclusive interview with Diwan FM on May 18, 2026, Dr. Derouaz explained that her invention relies on a technology that enables a car engine to run on gasoline, diesel, electricity, and used cooking oil, which is repurposed as a biofuel.
The Birth of a Revolutionary Idea
According to Dr. Derouaz, the concept for this invention was born out of a personal experience in 2021, when a mechanical malfunction occurred in her vehicle due to an error related to the type of fuel used. This incident sparked the idea for a more versatile and sustainable engine.
A Breakthrough in Automotive Engineering
The prototype was designed using artificial intelligence and data analysis techniques, as part of a three-year research and development project. Dr. Derouaz emphasized that this achievement marks a significant milestone for a Tunisian and Arab woman in the field of automotive engineering, registered in the United States.
A Trailblazer in Innovation
This is not Dr. Derouaz's first achievement in innovation. In 2023, she received a patent and an award in the fields of environment and agriculture. Her groundbreaking work has paved the way for a more sustainable and efficient future in the automotive industry.
Key Highlights:
- Revolutionary Hybrid Car Engine: Operates on four different energy sources: gasoline, diesel, electricity, and used cooking oil.
- Artificial Intelligence and Data Analysis: Used to design the prototype.
- First Tunisian and Arab Woman: To receive a US patent in automotive engineering.
- Previous Achievements: Received a patent and an award in environment and agriculture in 2023.
