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 recalling nearly 24,000 Focus EV and C-Max models over door chime

Ford will be voluntarily recalling 23,830 Focus Electric and C-Max Hybrid and Energi models equipped with push-button ignition, according to The Detroit News. Why? Because the cars don't make a noise when the driver's door is open, and are therefore in violation of federal regulations. It's not as silly as Honda's badging recall that isn't a recall, but it's close.
Actually, that's not exactly fair. The chime is supposed to come on when the driver's door is open, as it reminds drivers not to leave their cars on or leave key fobs in the car, an easy thing to forget when the cars in question make virtually no noise at idle and do not require keys in ignitions.
The recall, which Ford is conducting voluntarily, covers 2012 and 2013 Focus Electric hatchbacks and 2013 C-Max Hybrid and Energi models. The overwhelming majority, around 22,900 units, were sold in the US, while the remaining 900 units are in Canada. How many of each model are covered in the recall is not immediately clear.

Auto industry insider previews tell-all book, What Did Jesus Drive?

"It's about some of the biggest crises in history. It's about who did it right and who did it wrong." - Jason Vines
Jason Vines, the former head of public relations at Chrysler, Ford and Nissan, has seen a lot during his more than 30-year career, and now he's offering a behind-the-scenes look at the auto industry in his tell-all book What Did Jesus Drive? that went on sale this month.
