Zajac Motors - Platform for Complete Combustion
The Zajac Technology | Intellectual Property and Patents

Zajac Motors holds many patented and patents-pending technologies that reflect the company’s commitment to forward-thinking and creative "out-of-the-box" problem solving.  

The Zajac engine technology concept is truly unique.

The Zajac approach utilizes advanced valve, combustion chamber, material, and computer technologies. Without these “enabling” components, the Zajac engine would not be possible and thus could not be built before now.

Intellectual Property
Zajac Motors highly values its intellectual property.  To date, eighteen United States patents have been issued/allowed with additional patents pending or filed.  International patents have also been filed.  Zajac Motors expects to be filing for additional technology patents as the company's intellectual property continues to grow.
