EcoMotors (EM), the developer of opposed-piston opposed-cylinder (opoc) engine technology, purchased Katech, Inc., a manufacturing company known for developing advanced engines and powertrains.

The purchase comes on the heels of news of EM’s $200+ million joint venture with First Auto Works Jingye Engine Company to develop, manufacture, sell and service the opoc engine technology in China.

EM will use Katech’s proven testing, research and development, and manufacturing capabilities to continue to research, design and build advanced engine technologies that seek to redefine the internal combustion engine, while maintaining Katech’s core business and providing new paths for growth.

EM has appointed Tony Mannarino as CEO of Katech and to oversee day-to-day operations. Former Katech CEO John F. (Fritz) Kayl will maintain a consulting role with the company. Under EM, Katech will continue to operate as the Katech brand, maintaining its current business operations and staff.

EM is a privately held company, founded in 2008, whose primary investors are Khosla Ventures, Bill Gates and Braemar Energy Ventures. The opoc engine architecture is smaller and lighter than conventional engines, with 50% fewer components.

Katech specializes in design, prototyping, testing, research and development, and manufacturing of engines and engine technology. Katech has developed and produced technology for multiple automakers, including General Motors, Ford and Chrysler. Katech engines have also powered the GM Corvette Racing team.
