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 recalls select Explorer, E-Series vans

Just a few days ago we brought you news that Ford had issued a recall on 28,000 units of the Edge crossover for problems related to the fuel line. But now the Blue Oval has issued recall notices on two more of its larger vehicles.
The first relates to the Explorer, 395 examples of which from the 2011 and 2012 model years were found to have problems with their steering systems if they underwent service after September 1, 2013. An apparent software glitch could lock the steering gear, preventing the driver from steering the vehicle and thereby increasing the risk of a crash. As a result, Ford dealers are being instructed to check their records to identify the problematic vehicles and bring them in to have the steering gear replaced. Details of the recall can be found in the PDF linked here.
The second problem revolves around E-Series vans that may develop bubbles in their windshields under hot temperatures. The decrease in visibility through the problematic windshield could - you guessed it - "increase the risk of a crash." As a result, Ford is calling in 4,532 units of the E-150, E-250, E-350 and E-450 vans built in the relatively short window between May 12 and May 26, 2011. Details of this recall can be found in the notice below from the National Highway Traffic Safety Administration.

RTR Spec 5 Concept shows off 2015 Ford Mustang's drifty potential

Meet the Ford Mustang RTR Spec 5 Concept, a fully functional drift car that, according to our team in Sin City, has been doling out demo drifts in front of the Las Vegas Convention Center.
Destined to be the flagship of RTR's Tactical Performance Line, the Spec 5 Concept is, in addition to its 5.0-liter Aluminator V8 engine, chock full of performance parts that you can buy for your very own 2015 Mustang. In addition to the Ford Racing engine, the OEM parts supplier has lent the Spec 5 an aluminum radiator and a close-ratio six-speed transmission.
ASD Motorsports provided the front lower control arms, while the car itself rides on a fully customized coilover suspension. Magnaflow and American Racing have provided the exhaust system and headers, respectively. 20-inch HRE wheels, designed for RTR, are wrapped in sticky Nitto rubber.
