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 finally issues recall for 230K minivans over rust problems

The rust issue in the rear wheel wells of 2004-2007 Ford Freestar and Mercury Monterey minivans has finally led to a recall. The National Highway Traffic Safety Administration began an investigation into the matter in 2011, said investigation being upgraded to an engineering analysis a year later while NHTSA tried to figure out how many model years should be included in the assessment.
Ford has decided to recall all of the 230,000 minivans potentially affected, namely those sold in salt-belt states and countries like Canada. The excess rust in the rear wheel wells was also able to prevent the third-row seats from locking to the floor of the minivan. To repair the problem, owners can take their minivans to dealers, and the dealers will place new panels in the wheel wells, replace the third-row seat mounting brackets and relocate the latches to an area away from any corrosion.
Ford says it will begin notifying owners during the last week of March.

Mercury rises around sexy Cougar pack

With a slightly larger body and a more luxurious interior, the Mercury Cougar doesn't carry quite as much cachet among pony car enthusiasts as the venerable Ford Mustang. But don't try to make that argument around Cougar super-fan Mike Brown. Since starting his Cougar collecting in 1988, Brown has become an absolute expert on the model, and he claims to have owned 400 of the Mercury pony cars in that time. Ten of them are in his collection today, not to mention a heap of spare parts in the garage. Check out some of the rarer members of Brown's fleet and allow him to tell you about them in this interesting interview from Electric Federal.
