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 C-Max sales hold steady despite fuel economy fracas

Despite the ballyhoo that accompanied Ford's lowering of the C-Max fuel economy figures, the Blue Oval is still seeing strong demand for the five-seat MPV, as Automotive News reports. Speaking to marketing boss Jim Farley, AN says that the controversy surrounding the C-Max's fuel economy figures won't force Ford to change its marketing strategy.
Ford lowered the fuel economy rating of the C-Max after public outcry and legal action by customers that were unable to reach the 47 miles per gallon promised by the window sticker. The new ratings were dropped about a month ago to 45 mpg on the freeway and 40 mpg in the city. Ford offered rebates for current C-Max owners, with $550 going to those that bought their car and $325 to lessees. The issue, says Ford, stemmed from testing standards that allowed the automaker to base the C-Max's fuel economy on the Fusion Hybrid, because they use identical powertrains. The C-Max's less aerodynamic shape wasn't taken into account, though.
Whether Ford's PR team handled the crises perfectly or people just aren't that bothered by a four-mpg drop in combined ratings, demand remains strong for the C-Max among consumers. Ford moved 3,000 units in August, which was a 12-percent jump over July sales. Meanwhile, consumer demand through third-party shopping websites remains strong as well, according to Autometrics, a data analysis company that spoke with Automotive News. While the long-term effects of the adjustments remain unknown, the C-Max appears to have fared well in the near term.

New Ford Police Interceptor tech protects cops' backsides

It was only a matter of time before law enforcement agencies would realize the potential of driver-assist technology for use in their Ford Police Interceptors, and, now that they have, those back-up cameras and radar systems won't be used just for parking, but for security, as well.
The surveillance mode system works when the camera or radar detects movement from behind the vehicle, and if it does when it's activated, an alarm will alert the officer inside the car, the driver's side window will roll up and the doors will lock, protecting the officer from an unwanted intrusion. The officer, of course, has the option to turn surveillance mode off, mainly in urban areas where pedestrians would constantly set the alarm off, and it can only be activated when the police car is in park.
Randy Freiburger, Ford's police and ambulance fleet supervisor, came up with the patent-pending idea when researching the needs of police officers and riding along with them, during which time he realized officers would be safer with an extra set of eyes watching the area behind their cars, especially at night or when they're completing paperwork, using the in-car computer or handling a radar gun. "Unfortunately, there are people with bad intentions who sneak up on police officers," he says.
