EcoMotors

EcoMotors was an American company developing and commercializing an opposed-piston opposed-cylinder (OPOC) engine for use in cars, light trucks, commercial vehicles, aerospace, marine, agriculture, auxiliary power units, generators, etc.

The two primary investors in EcoMotors were Khosla Ventures and Bill Gates.

In April 2013 EcoMotors announced a deal to have Chinese auto parts giant Zhongding Power build a $200 million factory in the Anhui Province in eastern China.

The factory hoped to produce 150,000 OPOC engines per year, with a further site reserved to take production to 400,000.
