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.

IIHS says these are the safest cars of 2013

The Insurance Institute for Highway Safety (IIHS) has revealed its annual list of Top Safety Picks, an award that highlights automobiles it says offer "superior crash protection." A new and still more significant award, the Top Safety Pick+ honor, is given to those vehicles that earn good ratings for occupant protection in four out of five areas of measure. And while some 117 vehicles were given the TSP seal of approval for 2013, just 13 passed muster for TSP+.
To be fair, IIHS only evaluated 29 vehicles with its new testing procedures for TSP+ (we'd expect that the number of qualified cars will rise substantially for 2014). Luxury and Near Luxury midsize cars were the first groups evaluated, followed by midsizers in the Moderately Priced Cars category - unsurprisingly, it's only midsize cars that you'll find among the class this year.
Only two luxury sedans made the list of 13 for 2013: the Acura TL and Volvo S60. The other 11 cars on the list included entries from domestic, Japanese and German car makers: Dodge Avenger, Chrysler 200, Ford Fusion, Honda Accord (sedan and coupe), Kia Optima (but not its close kin, the Hyundai Sonata, strangely), Nissan Altima, Subaru Legacy and Outback, Suzuki Kizashi and the Volkswagen Passat all made the grade.

Now you can 3D print your favorite new Ford

Ford is letting people build their own cars, offering digital files so people can print 3D versions of their favorite models. This is way cooler than any old Matchbox or Hot Wheels toy. Ford this week started offering printable files for the F-150 Raptor, Shelby GT350R, Focus ST and Fiesta ST. Folks can order the 3D models in 1:32 scale in plastic (that'd make the mighty large pickup truck about eight inches long) but the digital files let users tweak the scale to the their liking. Once people have the digital files, they can print out their own miniature versions of the cars, made out of soft plastics, sandstone, and even some metals. Ford says it expects demand for such files to grow as sales numbers for desktop 3D printers surges to 1 million units in 2018. That's up from about 44,000 last year. Ford already offers digital files for its company logo, the 1.0-liter engine block, and two older Mustang models. But these new models take this to a totally different scale. Check out Ford's press release below. PRINT YOUR FAVORITE FORD VEHICLE AT HOME: FORD FIRST AUTOMAKER TO OPEN ONE-STOP 3D SHOP ONLINE - Consumers can now download digital images and 3D-printable files of Ford vehicles at the first-ever automaker-licensed, one-stop 3D shop online - The Ford 3D Store offers printable files of F-150 Raptor, Shelby GT350R, Focus ST and Fiesta ST; more models will become available later - Online store is powered by TurboSquid.com, the leader in providing automotive digital imaging and 3D-printable files Want to 3D-print a Shelby GT350R at home? Or would you prefer to simply purchase an F-150 Raptor 3D digital image for a presentation? How about both? Ford fans can now download digital images for Ford vehicles at the first-ever, automaker-authorized one-stop online store for 3D-printable vehicle files. The Ford 3D Store, 3d.ford.com, allows customers to use advanced technology to make their own models of Ford vehicles of the size and material they desire, or simply opt to purchase a 3D digital file from a growing library of more than 1,000 Ford images. "3D printing at home is a growing trend, and it makes sense for us to offer our customers a chance to make their own 3D Ford models," said Mark Bentley, licensing manager, Ford Global Brand Licensing.
