Electricity + gasoline = more mpg?

Wednesday, October 15th, 2008 by admin

Kids, do not try this at home. Researchers at Temple University have been experimenting with what happens when an electric current is run through fuel. Big boom, right? Well, apparently not.

According to a paper the Temple team has published in “Energy & Fuels”, done right, a small electric current applied to fuel just before it enters the combustion chamber, makes for much smaller droplets of fuel which burn cleaner and more efficiently. The team installed and tested their device on a diesel Mercedes where it showed a 20% decrease in fuel consumption in the lab.

The technology is currently being tested on a fleet of diesel trucks in Pennsylvania. How soon might you see it on a car lot? Actually you may see it on a late-night informercial first.

The company will most likely bring the tech to market is the same one running the Pennsylvania test: Save The World Air, Inc. That’s the same company that sells the MagChargR which is basically a magnet that supposedly does the same thing this new technology does. It’s also the same company that at one time was selling the Zero Emission Fuel Saver (ZEFS) device which was basically a magnet that, um, did the same thing. The RAND Corporation looked into ZEFS and found “at best mixed results.” STWA is also the company that was sued by the SEC for stock fraud.

So, maybe they’ve got something that works this time around, maybe not. The science sounds solid, but only time will tell if it translates into a working product.

Automotive X-Prize recommends EPA adopt MGEe rating

Wednesday, October 1st, 2008 by admin

Now that the California Air Resources Board (CARB) has an agreement with General Motors regarding how to measure the fuel mileage of the 2011 Chevy Volt, our attention turns to the EPA, which now has to decide what official mileage rating will appear on the new car’s window sticker and how to determine what that number will be. The first recommendation comes from the Automotive X-Prize, the foundation of which will award $10 million from Progressive Insurance to the winner of its competition to design a production-viable car that people would want to drive that gets 100 MPGe or more.

What’s with that little ‘e’ after the familiar miles per gallon? Basically, the X-Prize crew wants to convert all units of energy to a figure that’s equivalent to the power from a gallon of gas. That way, a car’s powerplant – regardless of where it gets that energy from – earns a rating that can be easily compared with everything else. So, EPA, the ball’s in your court… still.

More cars than ever require premium fuel

Economy, Fuel, High Octane, High Test, HighOctane, HighTest, Mileage, MPG, Premium

Whether you call it “premium,” “super unleaded,” or even “high test,” it all means the same thing — the most expensive gasoline at the pump (except maybe diesel). In a somewhat counterproductive trend, the skyrocketing cost of fuel is forcing automobile manufacturers to use smaller and more powerful engines, often with forced-induction. Unfortunately, these engines require higher octane… the distinguishing feature of premium fuel.

Kelley Blue Book has been following the trend and according to their analysis, there were 166 vehicle models that required premium fuel in 2002. This year, that number is up to 282. While some automakers only require premium for their highest performing models, companies like BMW call for premium fuel across their model range.

While there is no advantage to running premium fuel in an engine that doesn’t call for it, you should run the higher octane fuel in a powerplant designed for it (if in doubt, check the owner’s manual, or the inside of the fuel filler door). While nearly every late-model high-performance engine on the road can handle a slightly lower octane rating without damage, don’t skimp when filling up as your fuel economy and horsepower will suffer (yes, it will likely negate any savings at the pump).

SAE Congress ‘08: EPA rep says 75 mpg required by 2030s to reach GHG goals

Thursday, April 17th, 2008 by admin

margo-oge, mpg, sae-congress

At the SAE Congress this week, the director of the EPA’s Office of Transportation and Air Quality, Margo Oge, said that in order to cut greenhouse gas emissions by 50 percent compared to 2000 levels (something the Detroit News called a proposal that is “widely backed” in the scientific community), a new CAFE standard of 75 mpg would need to be implemented. And you thought you heard a howl when the 35 mpg by 2020 limit was imposed late last year. How could cars reach that goal? Oge suggests improvements in both engines and fuels. Glad that was figured out.

While 75 mpg is a fanciful fight we’ll leave for another day, this line jumped out at me in the Detroit News piece: “Oge said the auto industry should be able to meet the 35 mpg standard by 2018 with the same size fleet, with cost-effective technology improvements, based on an internal EPA study.” By 2018? Cool. Where’s the pressure to move the CAFE law’s implementation up two years?
