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.

Winnebago re-introduces classic Brave RV [w/video]

Winnebago is saying 'Let's do the time warp again,' using its new Brave RV to do it – have a look at the first Winnebago RV from 1966 and you'll know exactly where this one comes from. The modern version of this swinging sixties motorhome is accurate from its size, either 26- or 27-foot version, to its trademark eyebrow above the front windshield. The foldaway bunk above the front seats that necessitated the eyebrow design has been updated, and is now a power bed that descends from the ceiling. It is among a set of standard features that also includes a 19-foot motorized awning, leveling jacks at all four corners, heated mirrors, LED ceiling lights, two available floorplans and detailing like a workstation for the front passenger, a sliding dash cluster and and a waterfall countertop in the kitchen with built-in extensions. The Brave sits on a Ford F53 chassis complete with its Triton V10 engine and five-speed automatic transmission. No word yet on any potential diesel alternatives. Naturally, that 1966 price of $4,000 will also come in for an update, but the company hasn't yet revealed it. The good folks from Winnebago will be happy to take you on a thorough personal tour of the Brave in the video below. This content is hosted by a third party.

Which is more fuel efficient, driving with a pickup's tailgate up or down?

Thanks to the smoke wand in the wind tunnel, you can actually see the difference in our video.
Should you drive with your pickup truck's tailgate up or down? It's an age-old controversy that's divided drivers for decades. Traditionalists will swear you should leave the tailgate down. Makes sense, right? It would seem to let the air flow more cleanly over the body and through the bed. But there's also a school of thought that argues trucks are designed to look and operate in a specific manner, and modern design techniques can help channel the airflow properly. So don't mess with all of that: Leave the tailgate up.
