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 pits Cobra Jet versus GRC Fiesta ST, worlds collide

Racing takes on many forms in the automotive world. There are sanctioned events that are as varied and diverse as NASCAR, Formula One, Global Rallycross and drag racing, and to be good enough to win competitively in one discipline, you need to have a specialized vehicle. Or do you?
Ford decided to find out what would happen when its Global Rallycross Fiesta ST, driven by Tanner Foust, lined up against its Mustang Cobra Jet drag racer, driven by Roy Hill. In one lane, Tanner has just 2.0 liters of displacement to work with, while Roy has more than double that, at 5.0 liters. Evening the playing field a bit, Tanner has a massive turbocharger and all-wheel drive; Roy has to filter all his supercharged power through the rear wheels only.
So, who wins? We suggest you see for yourself in the press release and video below. And we're holding out hope that Tanner's challenge at the end results in another video from Ford Racing...
