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.

NHTSA investigating 725k Ford, Mercury vehicles for stalling issue

Owners of Ford Escape, Mercury Mariner, Ford Fusion and Mercury Milan models, listen up. According to a report on Automotive News, the National Highway Traffic Safety Administration has opened an investigation into these four vehicles totaling an estimated 725,000 units. The investigation appears to center around a malfunctioning throttle body on non-hybrid models of the 2005-2012 Escape and 2011-2012 Fusion. With Mercury dying off after the 2011 model year, this probe will also apply to the 2005 through 2011 Mariner and the 2011 Milan. There has been some discussion around the Escape stalling issue for some time now, but this investigation appears to be larger in scope than before.
Though not a recall yet, NHTSA's Office of Defects Investigation (ODI) has received 123 complaints of stalling or surging vehicles, while Ford itself has logged 1,472 complaints. The investigation report, which is posted below, seems to indicate that a faulty circuit board for the throttle body could cause the vehicle to go into limp mode, which, according to NHTSA, could cause complaints of both stalling and surging.

Auto Show Notebook: Legendary Continental name inspired Lincoln's designers

What's in a name? A lot for the Continental concept, and it gave Lincoln designers a sense of purpose as they styled the brand's upcoming flagship sedan. "The moment that we told them, it was amazing," Lincoln president Kumar Galhotra said. "They totally got it." "It" is cutting-edge technology wrapped in stately, large-sedan design. It's a nod to Lincoln's storied past, but a signpost for where the brand is heading. Though the Continental name dates to the late 1930s, Lincoln designers avoided making the concept overtly retro. "You can't let it pull yourself back too far in history, but you've got to design a car that lives up to the name," Galhotra said. Speaking to Autoblog on the floor of the New York Auto Show where the Continental formally debuted Wednesday, the Lincoln president reiterated that the car is on track to launch in 2016. It will compete against the Audi A6, Lexus GS, BMW 5 Series and other large luxury sedans. After its debut, the concept in New York will fly to China – another critical market for Lincoln – for display there. It will be replaced in New York by a prototype without an interior. The Continental is the latest high profile play by Lincoln to raise its image with consumers, who have either ignored or forgotten about it amid steep competition in the luxury sector from German and Japanese brands and a potentially resilient Cadillac. Lincoln sales are essentially flat compared with 2014 through the first quarter of this year, with total volume of 21,478 units. The middling start to 2015 comes on the heels of nearly 16-percent sales growth last year spurred by the launch of the MKC and the prominent signing of Matthew McConaughey to star in Lincoln advertisements. Other News, Notes & Quotes Speaking of names, Chevrolet did its homework before deciding to proceed with "Malibu" for its new generation of midsize cars. "We went out and researched it," said Alan Batey, president of General Motors North America. "People actually like the name 'Malibu,'" he said. Admittedly, the current Malibu has struggled in the marketplace against entrenched competitors, Batey said, but he's optimistic its awareness and historical value are assets to the dramatically redesigned sedan."The name's strong," he said. Meanwhile, in other Chevy news, the brand kicked off a new marketing campaign, "Real People, Not Actors" Wednesday. It will show consumers interacting with Chevys and their spontaneous reactions to the vehicles.
