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.

Autoblog joins Elon Musk and Danica Patrick in accepting ALS Ice Bucket Challenge

Unless you've been living in an off-the-grid cabin in the woods for the last couple of weeks or abstain entirely from social media activities, you've probably seen someone you know dump a bucket of ice and water over their own head recently. While the origins of the so-called Ice Bucket Challenge are shrouded in a history typical of Internet memes, its effectiveness in raising money and awareness for the ALS Association has been astonishing.
Celebrities from the worlds of entertainment, sports, technology and more have generated untold millions of video views in support of the organization that is helping patients with Amyotrophic Lateral Sclerosis (ALS, better known as Lou Gehrig's Disease), and generated a much needed influx of cash, as well. Recent reports have some $15.6M raised in the last two weeks.
Of course, the big-hearted world of automotive celebrities has taken part in the drenching charity effort as well. Follow on below for some of the biggest names on four wheels getting iced for charity, with a smattering of your favorite Autobloggers thrown in for good measure.

2015 F-150 launch to curb Ford profits?

Ford is making a big bet on aluminum with its new 2015 F-150, and it's possible that the decision will hurt the company financially, at least in the short term. After earning a record $8.6 billion in 2013, the Blue Oval does not expect to set another record in 2014. According to Automotive News, that's "largely attributable to F Series," says Bob Shanks, Ford's Chief Financial Officer.
To retool for the new F-150, Ford will idle its Dearborn Truck Plant in Michigan for 11 weeks and the Ford Kansas City Assembly Plant in Missouri for 2 weeks. "3 of the 13 overall weeks occur during what normally is our summer shutdown timeframe," said Mike Levine, Ford Trucks Communication Manager, in an email to Autoblog. The extra 10 weeks will be preparing for the more aluminum-intensive construction for the trucks and will mean over 2 months of no F-150s being made. For comparison's sake, Chrysler boss Sergio Marchionne just confirmed that the 200 plant in Sterling Heights, MI will be down for 30 days to retool for the new model, but obviously there are many more F-150 production variables than for the midsize sedan.
Levine notes that Ford is already running three shifts at both plants, and says the automaker has plans to ensure that there is adequate supply of the full-size pickups during the retooling process. The company does not want to suffer a shortage of the vehicle that accounted for 31-percent of its 2013 US sales and an even bigger percentage of its profits.
