Optimizing Engines for Ethanol

A Michigan-based engineering firm has reportedly developed technology to optimize engines for ethanol.

ricardoAccording to a press release from Ricardo, Inc., the technology “optimizes ethanol-fueled engines to a level of performance that exceeds gasoline engine efficiency and approaches levels previously reached only by diesel engines.”

The technology, called Ethanol Boosted Direct Injection or EBDI, takes full advantage of ethanol’s best properties – higher octane and higher heat of vaporization – to create a truly renewable fuel scenario that is independent of the cost of oil.

“Developing renewable energy applications that can lead to energy independence is a top priority at Ricardo,” said Ricardo President Dean Harlow. “We’ve moved past theoretical discussion and are busy applying renewable energy technology to the real world. The EBDI engine project is a great example because it turns the gasoline-ethanol equation upside down. It has the performance of diesel, at the cost of ethanol, and runs on ethanol, gasoline, or a blend of both.”

EBDI solves many of the challenges faced by flex-fuel engines because it is optimized for both alternative fuels and gasoline. Current flex-fuel engines pay a fuel economy penalty of about 30 percent compared to gasoline when operated on ethanol blends such as E85. The EBDI engine substantially improves ethanol’s efficiency, and performs at a level comparable to a diesel engine.
