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.

Question of the Day: Most degraded car name?

When Ford came up with a not-so-sporty version of the Pinto and slapped Mustang badges on it in 1974, that was a low point for the Mustang name. When Chrysler applied the venerable Town & Country name on perfectly functional but unglamorous minivans, it saddened many of us. But perhaps the biggest demotion for a once-proud model came when, in 1988, General Motors imported a misery-enhancing Daewoo from Korea and called it the Pontiac LeMans. The original Pontiac LeMans was a great-looking midsize car with fairly advanced (for the time) suspension design and engine options including potent V8s and a screaming overhead-cam straight-six. The Daewoo-based Pontiac LeMans was a cramped, shoddy hooptie that served only to ruin the LeMans name forever, while stealing sales from the Suzuki-based Chevrolet Sprint. Sure, using the once-respected Monterey name on the Mercurized Ford Freestar was bad, but Mercury didn't have long to live at that point. I say the downward spiral of the LeMans name was the most agonizing in automotive history. What do you think? Related Video: This content is hosted by a third party.

Ford recalling 450,000 Fusion, Mercury Milan sedans

Ford has announced a pair of recalls, and both are critical safety issues. The exponentially larger of the two recall campaigns affects over 450,000 Ford Fusion and Mercury Milan sedans manufactured at the Hermosillo plant between July 21, 2008, and March 4, 2011. The canister purge valve in the fuel tank could malfunction and could cause the top of the tank to crack and leak fuel. That could cause a fire, although Ford "is not aware of any accidents, injuries or fires" resulting from the issue. Affected vehicles will have their ECU software updated and their fuel tanks inspected for potential replacement. The company estimates there are 411,205 affected units in the United States (and its federalized territories), plus another 33,605 in Canada, and 7,055 in Mexico. The second recall affects 13 F-650 trucks. The column shifter's park position mechanism may fracture and let the truck roll away unexpectedly. Those 2016 models built in Ohio between July 29 and September 3, 2015 are all located in the US. Fixing the problem will require replacing the steering column and reconfiguring the instrument panel. FORD ISSUES TWO SAFETY RECALLS IN NORTH AMERICA DEARBORN, Mich., Nov. 23, 2015 – Ford Motor Company is issuing two safety recalls in North America. Ford is not aware of any accidents, injuries or fires related to these conditions. Details are as follows: Ford issues safety recall for certain 2010-2011 Ford Fusion and Mercury Milan vehicles in North America for potential fuel tank issue Ford Motor Company is issuing a safety recall for approximately 450,000 2010-2011 Ford Fusion and Mercury Milan vehicles for a potential issue with the fuel tank. Some of these vehicles might have a canister purge valve that does not work properly, causing internal pressure changes inside the fuel tank. Repeated pressure changes inside the tank could result in a crack on the top of the tank, possibly allowing fuel to leak. A fuel leak in the presence of an ignition source can lead to a fire. Ford is not aware of any accidents, injuries or fires related to this condition. Affected vehicles include certain 2010-2011 Ford Fusion and Mercury Milan vehicles built at Hermosillo Assembly Plant from July 21, 2008 through March 4, 2011. There are a total of approximately 451,865 vehicles that might be affected in North America, including 411,205 vehicles in the United States and federalized territories, 33,605 in Canada and 7,055 in Mexico.
