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 investigating 725k Ford, Mercury vehicles for stalling issue

Owners of Ford Escape, Mercury Mariner, Ford Fusion and Mercury Milan models, listen up. According to a report on Automotive News, the National Highway Traffic Safety Administration has opened an investigation into these four vehicles totaling an estimated 725,000 units. The investigation appears to center around a malfunctioning throttle body on non-hybrid models of the 2005-2012 Escape and 2011-2012 Fusion. With Mercury dying off after the 2011 model year, this probe will also apply to the 2005 through 2011 Mariner and the 2011 Milan. There has been some discussion around the Escape stalling issue for some time now, but this investigation appears to be larger in scope than before.
Though not a recall yet, NHTSA's Office of Defects Investigation (ODI) has received 123 complaints of stalling or surging vehicles, while Ford itself has logged 1,472 complaints. The investigation report, which is posted below, seems to indicate that a faulty circuit board for the throttle body could cause the vehicle to go into limp mode, which, according to NHTSA, could cause complaints of both stalling and surging.
