Ford finds flex-fuel engine design plays big role in emissions output

How bad is ethanol for your engine? There's been a lot of debate on this issue as the US considers upping the biofuel content in the national gasoline supply from 10 percent (E10) to 15 percent (E15). The ethanol industry and some scientists say higher ethanol blends show no "meaningful differences" in new engines while the oil industry says ethanol creates health risks. Researchers working at the Ford Research and Innovation Center decided to take a closer look at how a wide range of gas-ethanol blends - E0, E10, E20, E30, E40, E55 and E80 - affected the emissions coming out of a flex-fuel 2006 Mercury Grand Marquis. To see the full report, printed in the journal Environmental Science & Technology, requires payment, but there is an abstract and Green Car Congress has some more details. The gist is that, "with increasing ethanol content in the fuel, the tailpipe emissions of ethanol, acetaldehyde, formaldehyde, methane, and ammonia increased." At least NOx and NMHC emissions decreased. The researchers say that the effects are due to the fuel and "are expected for all FFVs," but that the way that a manufacturer calibrates the engine will affect NOx, THC, and NMOG emissions. It's this last bit that's important, since the researchers found, "Higher ethanol content in gasoline affects several fundamental fuel properties that can impact emissions. ... These changes can have positive or negative effects that can depend on engine design, hardware, and control strategy. In addition to direct emissions impacts, higher ethanol content fuel can also provide more efficient combustion and overall engine operation under part-load conditions and under knock-limited higher-load conditions." So, as we head towards more ethanol in our fuel supply (maybe), manufacturers are going to need to learn how to burn it most efficiently.

European car sales up 8% in February

Three weeks ago an analyst increased projections for European car sales this year, expecting them to climb three percent compared to last year instead of 2.7 percent. That number is a postive sign after years of hard times but it turns out February was especially good, overall European sales climbing eight percent on a wave of southern European recovery and discounts - and this comes after five months of gains including January's 7.2-percent jump over the year before.
The only country of Europe's five largest markets to post a decline was France, just as it did in January, Germany, the UK and Italy posting solid double-digit numbers, Spain rocking the charts with an 18-percent increase because of a government program to encourage trade-ins.
The only brand to miss the wave was Volkswagen, dropping 0.8 percent as it watched the double-digit growth at sister brands Audi, Seat and Skoda lift the Volkswagen Group sales up by seven-percent. Peugeot overcame flat sales at Citroën to improve the group by 3.5 percent, BMW and the Mercedes-Benz/Smart combo rose by four percent, the Fiat group jumped 5.8 percent, Ford was up 11 percent, the Renault Group 11.5 percent, General Motors 12 percent and the Toyota clan by 14 percent.

Hands on with Ford Sync 3

It's kind of funny (not funny) how the infotainment systems in our vehicles seem to lag behind the consumer products in our pockets. Long after we had easy-to-use touchscreens on our phones, the glass panels in the center stack of our cars remained obstinately mired in the muck of technology past. We are happy to report it's getting better. We had a chance to go hands-on with the new Sync 3 system from Ford at a technology event. Not once were we struck by the urge to reach out and offer a bit of knuckled encouragement. The processors kept swiping smooth, and the voice recognition could understand even our mumbly mouthings. The voice prompts were certainly fewer and less frustrating than in times past. Ask for the nearest Indian restaurant, and it quickly brought up a list to choose from, ready to offer directions. Want to listen to NPR, just say the word. Sync 3 also improved its ability to get along with others, by which we mean it nicely integrates a range of apps from your phone and can incorporate their individual areas of expertise. With Pandora installed, we could ask for a particular playlist and it would begin streaming. If we wanted a certain artist, it would pull it from the phone's memory upon request. To get a sense of what how the new system functions, check out the video above for a quick look at the improved layout and a demonstration of its smoothness and smarts.
