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.

eBay Find of the Day: Mercury Marauder two-door convertible

Never underestimate what you'll see on eBay Motors. Take this unique creation, for example. Near as we can tell, it's the same 2002 Mercury Marauder that was modified into a two-door convertible by Ford for the 2002 Chicago Auto Show. According to the seller, this car still boasts its Eaton supercharger bolted to a 4.6-liter V8 engine, and at the time of its debut, the engine was rated at a lofty 335 horsepower. We have a hard time believing that the extra ponies would do much to offset the weight of the additional frame stiffeners and top mechanism on the car, however.
The vehicle is currently offered for sale by a dealer in Lansdale, Pennsylvania, though the listing is mum on how the convertible managed to make its way from Ford's Windy City show stand into the seller's inventory. If you like what you see, the machine can be yours for the princely sum of $75,000 or best offer. Head over to eBay Motors to take a gander at the listing.

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.
