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.

Curtain officially comes down on Mercury as dealers remove signage

The process of shutting down the Mercury is complete. Ford officially made the decision to close its mid-level brand in June of 2010. In the months that followed, Ford offered its dealers money to stop selling the cars, with production shutting down in September. The last Mercury, a Mariner, rolled off the assembly line in the beginning of October and former spokesperson Jill Wagner said her good-byes to both the car and her job. Now the last piece of the brand has come down as dealers are removing any and all Mercury signage from their lots.

It's not been a great couple of weeks for Ford. On October 30, the company announced a 205,000-unit recall, and yesterday, it was revealed that the Ford brand's year-over-year sales were down over 5,000 units while the company itself was down 3,000 units over through October. Now, the company has announced five separate recalls affecting 202,000 vehicles built between 2005 and 2014.
