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.

Toyota Camry, Honda Civic inventories mounting as US automakers make inroads

Two of the hottest-selling cars in America aren't quite as hot as they used to be. The Toyota Camry and Honda Civic are both seeing dealer supplies increase in the face of renewed competition from the much-improved Detroit Three.
According to a report from The Detroit News, the Camry's dealer inventory is 15 days higher than its seasonal average, while the Civic is 25 days above average. Things aren't expected to get better for Toyota and Honda, as RBC Capital Markets analyst Joseph Spak marked the two Japanese offerings as "at risk for reduced output."
The Detroit Three, meanwhile, are seeing supplies dwindle as demand increases, especially for the Ford Fusion, which has seen an 18-percent increase in 2013 sales, and the Chevrolet Cruze, which was second only to the Camry in June 2013 sales.

More than 800,000 Fords recalled for faulty Takata airbags

The Basics: Ford is recalling about 816,000 Ford, Lincoln, and Mercury vehicles built in the US for faulty passenger-side Takata airbags. The affected vehicles were all built in North America, with 654,695 recalled vehicles in the US and 161,174 vehicles in Canada. A wide variety of cars, trucks, and SUVs are affected. This is a planned expansion of an earlier recall. 2005-09 and 2012 Ford Mustang 2005-06 Ford GT 2006-09 and 2012 Ford Fusion 2007-09 Ford Ranger 2007-09 Ford Edge 2006-09 and 2012 Lincoln Zephyr and Lincoln MKZ 2007-09 Lincoln MKX 2006-09 Mercury Milan The Problem: Like every other Takata recall, the problem rests with faulty airbags that can potentially expel shrapnel, injuring or killing vehicle occupants. Millions of vehicles from dozens of automakers are affected, so don't think that Ford is alone on this one. Injuries/Deaths: Ford stated in a press release that there have been no injuries or death linked to the vehicles in this recall. All in all, 11 deaths and 180 injuries across a variety of automakers have been linked to these Takata airbags. The fix: Ford will contact owners soon, and the affected vehicles will have their airbags replaced by a dealer at no additional charge. If you own one: Wait for contact from Ford, then head to the dealer to get a replacement. If you're wondering if your vehicle is affected, go to this Ford website and enter their Vehicle Identification Number (VIN). The recall reference number is 17S01.
