Ecomotors Reinvents the Internal Combustion Engine

Michigan based Ecomotors was founded in 2008 by Professor Peter Hofbauer who first began working on opposed-piston opposed-cylinder (OPOC) engines in 2003. Mr. Hofbauer is a career innovator with over 50 patents relating to advanced powertrains, combustion technologies and control systems. He was responsible for the creation and development of the first Volkswagen diesel engine.  Since inception, Ecomotors has taken in just over $58 million from Braemar Energy Ventures, Khosla Ventures, and  even Bill Gates who made his first investment in Ecomotors in 2010. He even blogged about his investment here.

OPOC Engines
The fuel economy of any engine is affected by friction, that is when metal engine parts are rubbing against each other at high speeds and over long periods of time. If you can reduce friction, you can dramatically improve the fuel economy of an engine. In all engines, there is a practical limit to piston speed above which engine performance begins to suffer from increasing friction. Piston speed is related to the distance the piston must travel. In an OPOC engine, each piston travels about half the distance of a piston in a conventional engine
