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.

Meet Shelby Mustang GT500 Miller, Iowa's latest hatchet-wielding criminal

Well, we've found the long-lost cousin of yesterday's Bentley-tattooed criminal from Florida. This is Shelby Mustang GT500 Miller. No, seriously. While his name seems just like the sort of thing we'd expect the Sunshine State to produce, he actually hails from Iowa. Despite coming from the Hawkeye State, Miller was arrested for a decidedly Floridian offense – getting in a bar fight and then returning with a hatchet. The only way this story could be more Florida is if meth, a manatee or bath salts were involved. The fight, which was at the Cheap Seats Sports Bar, started off typically enough, with a verbal argument in the parking lot (please, please let his nemesis be named "Chevrolet Camaro Z/28 Smith"). This, naturally, attracted passing police officers. Things were broken up and some friends took Miller to his home, which was apparently just behind the bar. That's when he returned with the hatchet tucked under his shirt. Miller promptly proceeded to take out the implement of destruction in the bar's bathroom and... forget about it entirely. Fortunately, the police hadn't left the area yet. Not surprisingly, Miller was arrested for a parole violation, as well as public intoxication and going armed with intent. Still, cool name, bro.

Ford F-150 EcoBoost in NHTSA probe for acceleration issue

According to Automotive News, the National Highway Traffic Safety Administration is launching a probe into 400,000 Ford F-150 models over possible acceleration problems. According to the article, NHTSA has received 95 reports "alleging incidents of reduced engine power during hard accelerations" on 2011 to 2013 F-150 models equipped with the company's 3.5-liter EcoBoost V6 engine.
Automotive News reports that Ford has issued three technical service bulletins "related to intermittent stumble/misfire on acceleration from highway cruise in humid or damp conditions," according to the government agency's documents. About one third of the 95 reports NHTSA has received cited humid or rainy conditions when these problems allegedly occurred.
These technical service bulletins have allowed dealers to address a "condition related to moisture accumulation in the charge air cooler during extended highway cruising at constant throttle in humid or damp conditions," AN reports, citing NHTSA documents. Furthermore, the TSB outlines details for "reprogramming the powertrain control module with the latest calibration and installing a new CAC and air deflector plate."
