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 recalls over 680,000 Ford Fusions, Mondeos, and Lincoln MKZs for seat belt pretensioners

Update: We spoke with a Ford representative who said that owners will be notified by mail during the week of January 16 . Dealers will also have the fix available at the same time. Owners can bring in their vehicles to dealers for an evaluation in the mean time. The main text has been updated to reflect this. The Basics: Ford is recalling 680,872 2013-2016 Ford Fusions, 2015-2016 Ford Mondeos, and 2013-2015 Lincoln MKZ s for an issue with front driver-side and passenger-side seat belt pretensioners. The Problem: The seat-belt pretensioners did not have sufficient insulation applied. When the pretensioners are activated, the heat generated can cause the cables connected to the belts to separate, which in turn can prevent the seat belts from effectively restraining the occupant. This can lead to injuries. Injuries/Deaths: Ford reports two accidents and two injuries have occurred that are related to this recall. The fix: A dealer technician will inject an insulation coating around the pretensioner. This should effectively keep the heat away from the cables, ensuring the seat belt will properly restrain the user in a collision. If you own one: Affected owners will be notified by mail on the week of January 16. Dealers will have the fix available that week, and owners will be able to bring in their vehicles for the fix to be implemented free of charge. Related Video:

F-150 just the start of Ford's aluminum plans

Not only have we been told that the 2015 Ford F-150 is tougher, more durable and up to 700 pounds lighter than the current truck, Ford COO Mark Fields said it's also "CAFE-positive." That means, for the first time in the history of corporate average fuel economy standards, the F-150 would be a positive contributor on Ford's CAFE balance sheet instead of being a vehicle it needs to counterbalance with frugal offerings.
Fields' comments made at the Detroit Auto Show were among quotes from other Ford execs that confirmed the carmaker will be using aluminum for more of its vehicles. CEO Alan Mulally said it would "proliferate across our lineup," with speculation being that we'll see it applied to crossover and sport utility models first, since they'll benefit the most. Even gaining the massive scale of using aluminum on the world's best selling vehicle for its first effort - on average, the company sells two times as many F-150s in a single day as Land Rover sells of its aluminum Range Rover in a month - Ford will be looking to further spread the cost of its five-year development investment in aluminum technology. And that should mean better handling and fuel economy for those of us who don't need to wear hardhats at the office.
