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.

More than 800,000 Fords recalled for faulty Takata airbags

The Basics: Ford is recalling about 816,000 Ford, Lincoln, and Mercury vehicles built in the US for faulty passenger-side Takata airbags. The affected vehicles were all built in North America, with 654,695 recalled vehicles in the US and 161,174 vehicles in Canada. A wide variety of cars, trucks, and SUVs are affected. This is a planned expansion of an earlier recall. 2005-09 and 2012 Ford Mustang 2005-06 Ford GT 2006-09 and 2012 Ford Fusion 2007-09 Ford Ranger 2007-09 Ford Edge 2006-09 and 2012 Lincoln Zephyr and Lincoln MKZ 2007-09 Lincoln MKX 2006-09 Mercury Milan The Problem: Like every other Takata recall, the problem rests with faulty airbags that can potentially expel shrapnel, injuring or killing vehicle occupants. Millions of vehicles from dozens of automakers are affected, so don't think that Ford is alone on this one. Injuries/Deaths: Ford stated in a press release that there have been no injuries or death linked to the vehicles in this recall. All in all, 11 deaths and 180 injuries across a variety of automakers have been linked to these Takata airbags. The fix: Ford will contact owners soon, and the affected vehicles will have their airbags replaced by a dealer at no additional charge. If you own one: Wait for contact from Ford, then head to the dealer to get a replacement. If you're wondering if your vehicle is affected, go to this Ford website and enter their Vehicle Identification Number (VIN). The recall reference number is 17S01.

NHTSA closes probes on Jeep Grand Cherokee, Ford Freestar and Mercury Monterey

The Detroit News reports the National Highway Traffic Safety Administration has officially closed its investigations into 2012 Jeep Grand Cherokee, 2004-2005 Ford Freestar and Mercury Monterey models. The separate probes found no issues that pose safety concerns. NHTSA began investigating certain Grand Cherokee SUVs over complaints that power steering hoses could detach during operation, thereby increasing the risk of a vehicle fire. Of the 24 reports of failure, none alleged smoke or fire in the engine bay, and Chrysler has since modified the power steering cooler assembly to reduce the likelihood of the failure.
Meanwhile, certain Ford Freestar and Mercury Monterey vehicles garnered a government probe after receiving complaints that the models were equipped with faulty scissor jacks. The agency had received six reports of the jacks failing or causing injuries, including one incident that resulted in a fatality. But NHTSA says the jack failure rate is similar to those found in other vehicles. In those six cases, the government agency found the jacks were being used for something other than changing a tire, and investigators could not determine whether the emergency brake was set or the rear tires were properly chocked.
