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.

Ford Transit Skyliner Concept is a Gulfstream for the road

If you are afraid to fly or just want to arrive at your ultimate destination in absolute comfort, then the Ford Transit Skyliner concept might be the perfect vehicle for you. Built by Galpin Auto Sports and based on a 2015 Transit, the van is basically a private jet on wheels. It even has a touch of Transformers about it with the ability to switch between four modes by pressing a button in a smartphone app.
Based on the long wheelbase, high-roof model with 487 cubic feet of cargo space and 6 feet, 9.5 inches of interior height, the Skyliner has movable captains chairs that shift around among four modes. In theater mode, the seats turn and recline to face a 52-inch retractable movie screen with 7.2 surround sound. For business, a motorized table unfolds, and the chairs gather around it. There is a mode for tailgating where the door opens four-feet wide, and, when traveling, passengers can recline back with footrests that extend for maximum comfort.
To make the ride even plusher, there is a satellite and media server to meet your entertainment needs, and there is even a built-in bar in the back. If this Ford had a bathroom, you could live in it. Of course, you would need to hire a driver to enjoy all the amenities in the back.
