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.

New 2020 Ford Explorer, Lincoln Aviator recalled for minor safety issues

Ford has announced a small recall on 2020 Explorers and 2020 Lincoln Aviators. Select units might be missing a manual park release cover, while others might have instrument clusters stuck in Factory Mode. The recall affects 14,135 SUVs in total.  While a vehicle is in production in a manufacturing facility, Ford might put them in what is known as Factory Mode to help reduce battery drain. Affecting the instrument cluster, this mode disables warning alerts, warning chimes, and does not show the PRNDL gear selector display. Ford says one vehicle was in an accident at a production facility as a result of the issue, but nobody was injured.  Separately, Ford found that some of these Explorers and Aviators might be lacking a manual park release cover. Federal Motor Vehicle Safety Standards require a manual park release cover that is only removable with a tool. Without the cover, there is a very minor chance the manual park release could be accidentally actuated, which could allow the vehicle to move on its own.  The recalls affect 13,896 vehicles in the U.S. and 239 in Canada. The Explorers were built between March 27, 2019, and July 24, 2019. The Aviators were built between April 10, 2019, and July 24, 2019. Owners can use Ford's recall number 19C06, and if affected, can take their vehicles in for fixes.

Next-gen Ford Cobra Jet development underway, but will it be a Mustang?

Ford might be stepping away from the NHRA, but it isn't abandoning drag racing altogether. Hot Rod says that Ford confirmed a next-gen Cobra Jet factory drag racer is in the works, but the report also speculates that a new Cobra Jet could switch away from the Mustang nameplate.
Even though talk of a new Cobra Jet coincides with the all-new 2015 Mustang, the lack of confirmation for the dragster's platform leaves Hot Rod to guess that the car might switch to another platform - specifically a front-drive-based, unibody car like the Fusion or Taurus. We'd hate to think of a world with a NASCAR-ized dragster from Ford Racing, but it's also highly unlikely that the Mustang Cobra Jet would step away from its quarter-mile rivals like the Chevy COPO Camaro and Dodge Challenger Drag Pak.
