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 announces free brake pad offer if customers stop by dealers

These days, when you buy a new car, it's not unreasonable to expect a certain period of free maintenance to come along as well. Sometimes this is through the life of the warranty, in other cases a little less. But Ford Motor Company is going beyond those deals for at least one part of its cars. As of now, if you buy a set of Motorcraft brake pads for a Ford, Lincoln or Mercury model, you get free replacements for as long as you own the vehicle. The offer is good at Ford or Lincoln dealers and Quick Lane Tire & Auto Centers.
"We will replace the pads for as long as you own the vehicle," said Elizabeth Weigandt to Autoblog. She did clarify that the Motorcraft pads are generally for models from the '90s or newer. Also, to take advantage of this program, a person must return to the same dealer each time to get the free parts.
Of course, Ford isn't just handing out brake pads to anyone who walks by; there are certain stipulations. First, the components have to be worn down to less than three millimeters to be eligible, and the buyer still has to pay for the labor to install them. If the model is used as a fleet vehicle for commercial purposes like as a taxi or limousine, this offer also doesn't apply; the same thing for racecars. On the plus side, if you recently bought a set of pads from one of the participating locations, you're still in luck. The deal covers parts purchased as of July 1.

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.
