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.

Hear the 2015 Mustang GT V8 roar for the first time

Our combined knowledge of the 2015 Ford Mustang continues to deepen, as spy shooters have begun to compile video and audio of the upcoming sixth-generation car.
Case in point is this latest series of video clips, which not only gives us a great vantage point of the Mustang in motion, but also allows us to hear the Ford V8 engine and exhaust. After perusing the aural delights of this short video, which, admittedly, doesn't catch the Mustang GT at full song, we can at least say that the throaty exhaust isn't disappointing.
Chances are good that the 2015 Mustang GT will debut with some version of the current (and excellent) Coyote 5.0-liter V8 engine, though we're unclear as to whether or not the motor has been massaged for its next-gen debut, or what may have been done to exhaust plumbing. At this point, we're just happy to hear the pony run. Scroll below to hear for yourself.

Ford idling Michigan Assembly Plant to trim Focus, C-Max supply

Ford will be putting the brakes on production at its Michigan Assembly Plant in Wayne, MI, idling production during the weeks of October 28 and December 16. Ford is citing the first drop in US sales in 27 months, a 4.2-percent dip in September, as the impetus for trimming their supplies, according to Automotive News.
Ford's deft management of its supplies has been part of its success over the years, and seeing supplies of Focus and C-Max, the two vehicles built at MAP, rise from 58 and 108 days, respectively, to 71 and 122 days over the span of a month was apparently all that was need to justify the trimming. As AN points out, the rule of thumb for many automakers is to maintain a 60-day supply of vehicles.
"Ford has been focused on keeping their pricing in check. Their operating margin is in double digits. Nobody else is there and they're obviously very proud of that," Alan Baum, an auto analyst with Baum & Associates told AN. Keeping the supply chain operating smoothly and not increasing supplies too much is crucial to that healthy profit margin. After all, a large supply lowers prices ,which, in turn, cuts profit. So while this news might not be great for employees at MAP, who now have an extra two weeks of vacation time, it's far from a sign of problems in Dearborn. Quite the opposite, actually.
