Forums: E85 In Standard Engines

Donning FDR's cape, Eisenhower's stripes and JFK's boat shoes, President Obama observed in Florida on Tuesday that his "clean energy economy" will require "mobilization" on the order of fighting World War II, building the interstate highway system and going to the moon. Of course, the only "mobilization" going on at the moment is on behalf of ethanol, whose many political dispensations the biofuels lobby is finding new ways to preserve even as the evidence of its destructiveness piles up. The latest embarrassment arrives via the peer-reviewed journal Science, not known for its right-wing inclinations. A new paper calls attention to...

Minnesota has been an unofficial testing ground for using ethanol to fuel vehicles, but after years of steady increases, interest appears to be waning. Despite a push from the governor and an increase in the number of so-called flexible-fuel vehicles on the road — which can run on either gasoline or a mostly ethanol blend — sales of E85 have dipped in recent months, beyond the normal decline in winter months. In February, sales of E85, a cleaner-burning fuel consisting of 85 percent ethanol and 15 percent gasoline, hit their lowest mark since 2006, according to a new report by...

A radical twin-fuel engine from Ford, code-named “Bobcat,” that variably blends gasoline and ethanol on demand to realize diesel-like performance continues to make steady progress in its development, according to presentations made by the automaker to the Department of Energy and Society of Automotive Engineers in April. The presentations also provide a first look at the engine’s architecture and make some remarkable claims about “E85-optimized” engine efficiency versus size.

Anyone interested in a car that gets 110 mpg, 400 hp, and 500 tq? Of course you are, but where can you get such an automobile? What if I told you that you just need to get the engine, and put it in your car? Awesome huh? A man has invented an E85 engine that gets all those stats. E85 is known for being very inefficient, but it delivers more horsepower to engines that can run on it while reducing mpg. All we needed was someone to make E85 efficient. Well, now we have.

Using a separate E85 direct injection boosting system combined with gasoline port fuel injection (PFI) makes the engine more efficient in its use of gasoline, and can be viewed as a more cost-effective alternative to a modern diesel, according to a Ford study presented by Robert Stein, currently of AVL, formerly of Ford, at the SAE 2009 World Congress.

It's time to start reflecting on the past year, and I want to kick mine off with some admissions on places where I was flat wrong. Compact Fluorescent Light Bulbs - boy, did I get on that train. When I found out that those little bulbs operated at roughly 1/3 the wattage of normal bulbs and they lasted for 5 years, I ran out and outfitted the entire house with them. I'm not some earth-worshiping, tree-hugging, enviro-nazi, by the way. I'm just a guy who loves technology, electronics, and efficiency, and who doesn't like to change light bulbs. One place...

HOUSTON, Aug. 7 -- The US Environmental Protection Agency has denied a request submitted by Texas Gov. Rick Perry for a 50% waiver from the federal renewable fuel standard (RFS) mandate for corn-based ethanol. The RFS, part of the Energy Independence and Security Act of 2007, requires increased national production of renewable biofuels to 36 billion gal/year by 2022 from 9 billion gal/year in 2008. Perry blamed increased demand for corn-based ethanol for contributing to escalating corn prices, which he said contributes to higher food prices and also higher costs for livestock feed (OGJ Online, July 22, 2008). EPA said...

"In terms of renewable fuels, ethanol is the worst solution," Patzek says. "It has the highest energy cost with the least benefit."Ethanol is produced by fermenting renewable crops like corn or sugarcane. It may sound green, Patzek says, but that's because many scientists are not looking at the whole picture. According to his research, more fossil energy is used to produce ethanol than the energy contained within it. Patzek's ethanol critique began during a freshman seminar he taught in which he and his students calculated the energy balance of the biofuel. Taking into account the energy required to grow the...
