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 recalls 600,000 older-model sedans for braking issue

Ford is recalling 600,166 older-model Ford, Lincoln and Mercury vehicles over an issue that could affect braking and increase the risk of a crash. The safety recall covers certain Ford Fusion, Mercury Milan and Lincoln MKZ sedans from the 2006 through 2010 model years that were built at Ford’s Hermosillo Assembly Plant in Mexico between Feb. 22, 2006, and July 15, 2009. Ford says a valve that is normally closed inside the hydraulic control unit may get stuck in the open position or be slow to close, which could make it harder to engage the brakes and increase risk of a crash. Ford says itÂ’s aware of 15 reports of accidents and two injuries possibly related to the issue. Dealers will inspect the hydraulic control unit for signs of the problem and replace it, if necessary. The dealers will pressure-flush the system with brake fluid and replace the reservoir cap with a new one. Ford is also issuing a small recall of 33 of its 2020 F-150 trucks in the U.S. and 51 in Canada over potentially damaged spare tires. It says the bead area on the tires may have been damaged when it was mounted onto the wheel assembly, leaving it vulnerable to corrosion, separation of the bead wire and ultimately a rapid loss of air pressure and detachment from the wheel. Dealers will replace the spare tire. Affected vehicles were built at the Dearborn Truck Plant from Nov. 10-21 of this year.

Report: Lincoln getting all of Mercury's ad dollars

Now that the curtain has closed on Mercury, Ford Motor Company will redirect all of its marketing dollars for the oft-overlooked brand to the Blue Oval's luxury outpost, Lincoln. In speaking to Automotive News, the chairman of the Lincoln National Dealer Council, Bob Tasca, Jr., said, "You'll see a lot stronger presence in the advertising of Lincoln in 2011."
Lincoln spokesperson Christian Bokich reminded AN that the automaker is "preparing the way for seven new or significantly refreshed vehicles" that will be launched over the next four years, and the largest ad blitz in 2011 will focus on the refreshed MKX crossover, as well as the MKZ sedan and its hybrid counterpart. Following that, Lincoln has plans to launch a completely overhauled version of its Navigator SUV, an all-new C-segment vehicle and the overhauled 2013 MKZ, which Tasca says will be "strikingly different from its Ford Fusion sibling."
