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.

Man turns Ford Fiesta into a one-car band

The one-man band is a rather ridiculous idea, drawing up images of one person attempting to manipulate several instruments, at once, in a vain attempt at creating music. It's usually represented by silly scenes like this. Interestingly, the concept isn't much more successful when the "man" in "one-man band" is replaced with "car," as we see in this video.
It seems that someone rigged up and edited (699 times, we might add) a Ford Fiesta, a bucket, 12 PVC pipes and the natural sounds that a car makes to come up with a song. Now, we don't recognize the tune, so we've no idea if this is a cover or an original piece. And while it's hardly Beethoven, we have to admire the amount of effort the "conductor" went to in his attempt to turn a subcompact car into a musical instrument(s). Take a look (or listen) below for the entire video.

Ford reveals concept trucks that ultimately became Atlas

The Ford Atlas Concept was one of the quiet success stories of the 2013 Detroit Auto Show, and now Ford has given us a quick glimpse as to how that creation came to be. Designers actually combined two early sketches to build the Atlas. One, called the Bullet Train, is a futuristic, aerodynamic creation, while the other, aptly named the Locomotive, features the squared off proportions we're familiar with.
Once designers settled on the truck's proportions, they began nailing down exactly which attributes they wanted the final design to have. The Concept's notched windshield originated as a forked glass roof that seamlessly transitioned into the windscreen.
Likewise, designers wanted to fit the truck's tailgate with a storage compartment for tools and a first aid kit, but settled on the dual-purpose step/cargo cradle. Interestingly enough, the concept's active aero shutter wheels actually originated in some of the earliest sketches. Check out the photos and slides here for a closer look.
