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 70k Escape and Mariner Hybrids for cooling issue

Ford is recalling about 70,209 examples of the 2005-2008 Ford Escape Hybrid and the 2006-2008 Mercury Mariner Hybrid because the cooling pumps for their hybrid systems could fail.
According to the company's defect notice, it's possible for the original "Motor Electronics Coolant (MEC) Pump" to wear out and fail, which would could cause the hybrid system to overheat. If this happens, the vehicle goes into a safety mode that takes away most or all of its power. However, braking and steering still operate normally. After cooling down, the affected models restart normally. The company says that it's not aware of any accidents or injuries related to this problem.
Ford will begin repairing the vehicles in late October, and dealers will be installing improved, brushless pumps on the affected models at no charge to owners. If drivers had their pumps fail before this recall, they can contact Ford for a possible reimbursement.

Does Lincoln Zephyr trademark mean a return to real names?

Lincoln's long history includes many legendary names, and despite its short life, Zephyr retains a spot in that pantheon. Perhaps its will return once again: Ford Motor Co. applied to trademark Zephyr on May 11. Trademark filings can have ambiguous meanings, and often they're legal plays to get or keep the rights to a name. But in the last year, we've seen signs Lincoln is looking to use real names on its vehicles again. Obviously, it's keeping Navigator for its flagship sport-utility vehicle with a new model due next year. Reprising Continental for the MKS replacement was also well received. That said, Lincoln still uses the MKX and MKC "names" for its crossovers. Zephyr is a dustier moniker. It was used in the 1930s and '40s on a mid-level model spearheaded by Edsel Ford. The stylishly aerodynamic model was set between the Ford V8 De Luxe and more expensive Lincolns. It returned in 2006 as the Lincoln version of the Ford Fusion before that model was renamed MKZ. Mercury also used Zephyr on its version of the Ford Fairmont in the late 1970s and early '80s. Ford last held a trademark on the Zephyr name in 2013. The filing says Ford seeks to use Zephyr for "motor vehicles and parts and accessories therefor." That could mean a new car — or just parts. Putting the Zephyr badge back on the MKZ is the most likely bet. Meanwhile, Ford also moved to get the Thunderbird trademark on May 11 for the same vehicles and parts purpose, and it filed for the Mustang trademark for shampoo and lotions on May 4. A Lincoln spokesman said, "In the normal course of our business, we file trademarks for names," but had no further information. Related Video:
