EcoMotors says its “opoc” engine technology can deliver the same power level as conventional engines at half the size, a lower cost, and lower emissions. With the potential for 20 to 50 percent better fuel economy compared to a conventional turbo-diesel engine, EcoMotors’ opoc engine has the potential to revolutionize the internal combustion engine.

The inaugural opoc plant has received the full support of key Chinese government bodies, including the Xuancheng government and Anhui provincial authorities; a second Zhongding production site may be announced at a later date. Zhongding plans to supply opoc engines to a broad range of customers, including generator engines, off-road and commercial vehicles. A key provision of the agreement allocates a portion of the plant’s output to EcoMotors for sale and distribution to its own direct customers.

“Continued progress in development of the opoc engine has brought us to the next phase of development,” said Xia Ding Hu, CEO of Zhongding Power. “With the enthusiastic backing from both our provincial and national governmental bodies, we are now ready to complete the design of the engine as we head toward launching a state-of-the-art opoc engine manufacturing facility in Anhui Province.”

With a full funding commitment from Zhongding, EcoMotors proves that with great technology, cleantech companies can indeed commercialize capital efficiently alongside visionary partners.”

“This agreement is a key milestone in bringing our innovative engine technology to market and underscores the potent disruptive force that is opoc,” said Don Runkle, CEO of EcoMotors who was former Vice Chairman and CTO of Delphi and a 30-year executive at General Motors. “Our game-changing 21st century internal-combustion opoc engine technology offers a unique combination of lower fuel consumption and operating costs at lower production costs.  These characteristics are important to progressive companies and countries as they seek to overcome environmental challenges of the future.”

Ltd. is a diversified international company established in 1980 with headquarters located within the economic and technical development zone of Ningguo, Anhui Province, China.
