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 expands door-latch recall to 156k more vehicles, nearly 550k total

Ford is being inundated with recalls as of late. Just days ago it called in over 590,000 cars for a variety of issues. Now, the Blue Oval has announced an expansion of its door latch campaign to cover an additional 156,000 vehicles in North America. Counting the original 389,585 cars, this has brought the total to 545,906. Under this expansion, the same models are affected, but Ford is broadening the coverage dates in some cases. The recall covers the 2011-2014 Fiesta, 2013-2014 Fusion, and 2013-2014 Lincoln MKZ; there are 456,440 units in the US, 50,681 in Canada, and 38,785 in Mexico in need of repair. In these vehicles, a door might not latch because of a broken pawl spring tab. Even if a passenger can successfully close it, the faulty part could unlatch while driving. According to Ford, there are two allegations of doors bounding back and hitting a person. There's also one possible accident from a door opening and striking another vehicle. Dealers will replace all of the latches to fix the problem. Related Video: MAY 1, 2015 | DEARBORN, MICH. FORD EXPANDS DOOR LATCH SAFETY RECALL IN NORTH AMERICA DEARBORN, Mich., May 1, 2015 – Ford Motor Company is expanding a safety recall regarding door latches to include approximately 156,000 more vehicles at the request of the National Highway Traffic Safety Administration, bringing the total to 545,906 vehicles in North America. The door latch in certain vehicles may experience a broken pawl spring tab, which typically results in a condition where the door will not latch. If a customer is then able to latch the door, there is a potential the door may unlatch while driving, increasing the risk of injury. Ford is aware of a total two allegations of soreness resulting from an unlatched door bouncing back when the customer attempted to close it, and one accident allegation when an unlatched door swung open and struck the adjacent vehicle as the driver was pulling into a parking space. Affected vehicles include certain 2011-14 Fiesta vehicles built at Cuautitlan Assembly Plant, Nov. 3, 2009 to May 31, 2013; certain 2013-14 Fusion vehicles built at Hermosillo Assembly Plant, Feb. 1, 2012 to May 31, 2013; certain 2014 Fusion vehicles built at Flat Rock Assembly Plant, April 12, 2013 to April 26, 2013; and certain 2013-14 Lincoln MKZ vehicles built at Hermosillo Assembly Plant, Feb. 1, 2012 to May 31, 2013. There are 456,440 vehicles in the United States and federalized territories, 50,681 in Canada and 38,785 in Mexico.

Ford gives police chiefs tech to surveil officers in their own cars

Police officers certainly have a difficult job in keeping the streets safe, but as public employees in positions of authority, there is still a very real need for oversight. To that end, Ford is partnering with a tech company to offer a new system called Ford Telematics for Law Enforcement on its line of Police Interceptor patrol vehicles that could make cops safer, while giving cities a better idea of what its officers are doing.
The system streams live data about cruisers back to the home base to people like the police chief or shift supervisor. That info includes expected things like speed, location and cornering acceleration, but it gets incredibly granular as well, with records of things like if emergency lights are on, or even if an officer is wearing a seatbelt.
Ford Telematics for Law Enforcement "ought to protect officers as much as it protects the public," said Ford spokesperson Chris Terry to Autoblog. Constantly monitoring patrol cars offers cities a lot of advantages, too. First, it reduces potential liability because a department can prove where each vehicle is at all times. Also, officers know they are being watched and may potentially drive more safely.
