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.

Massive Airbag Recall Affects Seven Automakers

The recall of faulty airbag inflators supplied by Takata has exploded today to grow to seven automakers. In most cases, only models in certain high-humidity regions were affected because the National Highway Traffic Safety Administration found in its investigation that moisture played a role in determining whether there would be a problem. However, some companies opted for national campaigns. The exact number of affected models for these campaigns isn't yet known at this time. BMW is recalling an undisclosed number of 325i, 325Xi, 330i and 330Xi models from the 2001 through 2005 model years and the 2001-2006 model year versions of the 325Ci and 330Ci for the driver side and passenger side inflators. Only vehicles currently registered in Florida, Puerto Rico, Hawaii and the US Virgin Islands are covered under this recall. Neither Chrysler's filing with NHTSA nor its press release list the specific models affected, but a company spokesperson told Autoblog that at this time it only covers the driver and passenger side inflators for the 2006 Dodge Charger in Florida, Puerto Rico, Hawaii and the US Virgin Islands In most cases, only models in certain high-humidity regions were affected because the NHTSA found that moisture played a roll in determining if there would be a problem. Ford is recalling an estimated 58,669 cars that include the 2005-2006 model years of the Ford GT for the driver and passenger inflators, the 2007-2007 model years of the Mustang for the driver side and 2004 Ranger for the passenger side. It covers vehicles originally sold or currently registered in, wait for it... Florida, Puerto Rico, Hawaii and the US Virgin Islands. Honda is issuing three separate recalls regarding the problem. First, the company is recalling the 2002-2003 model years Civic, CR-V and Odyssey and the 2003 model year of the Accord, Element, Pilot and Acura MDX to replace the passenger's side inflator. This covers all models nationwide. Second, Honda is repairing the passenger's side airbag inflator in the 2003-2005 Accord, Civic, CR-V, Element, Pilot, the 2003-2004 model year versions of the Odyssey, the 2003-2005 model year Acura MDX and 2005 Acura RL. However, only for vehicles located in Alabama, Florida, Georgia, Hawaii, Louisiana, Mississippi, South Carolina, Texas, Puerto Rico and the US Virgin Islands. Owners will be notified in July. Finally, Honda is separately replacing some models' driver's side inflators.
