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.

NHTSA closes rollaway investigation into 1.56M Ford SUVs

It's taken four years of study, but the National Highway Traffic Safety Administration has finally closed the books on its investigation into rollaway accusations surrounding 1.56-million Ford SUV models.
The probe, which centered on the 2002-2005 Ford Explorer, 2002-2005 Mercury Mountaineer and 2003-2005 Lincoln Aviator, ends without the federal agency calling for a recall. According to The Detroit News, the investigation was closed due to a "low number of complaints" - NHTSA documented 180 such complaints that resulted in 14 crashes and six minor injuries, but the number of incidents have been slowing. The suspected defect rate for the trucks' automatic transmissions was found to be 4.4 per 100,000 units, and the brake-shift interlock mechanism failure rate was judged to be even lower at 3.4 per 100k.

Ford recalling 370,000 Crown Vic, Grand Marquis and Town Car models

The Detroit News is reporting that Ford will recall some 370,000 Crown Victoria (pictured), Mercury Grand Marquis and Lincoln Town Car vehicles from model years 2005 through 2011, for an issue regarding the lower intermediate steering shaft. 355,000 of the vehicles in question were sold in the US, with the other 15,000 sold in Canada.
The report indicates that corrosion of the lower intermediate steering shaft could cause a "loss of steering," presumably because of a partial or complete failure of the part. The report points out the dealers will inspect and replace the offending steering component for recalled cars, and may also secure a lower steering column bearing and replace the upper intermediate steering shaft as needed. The company is unaware of any reports of the faulty part causing any accidents or injuries.
Ford helpfully lists states in which corrosion is more likely to have taken place, mostly in the Snow Belt, as you might guess. Connecticut, Delaware, Illinois, Indiana, Iowa, Kentucky, Maine, Maryland, Massachusetts, Michigan, Minnesota, Missouri, New Hampshire, New Jersey, New York, Ohio, Pennsylvania, Rhode Island, Vermont, Virginia, Wisconsin, West Virginia, and the District of Columbia are listed.
