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.

An in-depth look at the Ford GT with Xcar

Ford made big waves when it unveiled the new GT at the Detroit Auto Show this past January. But as far as details go, it's been rather quiet. Though Dearborn has revealed what engine will sit between those buttresses, it hasn't told us exactly how many horses or torques it will produce, or precisely how fast we should expect it to propel the new all-American supercar. Fortunately, the automaker let the crew at Xcar into the studio to give us a quick, four-minute rundown of all the information that is out there at the moment, along with all the most intriguing angles of the vehicle's design. The historically savvy among us will already know that the new 2016 Ford GT traces its roots back to the GT40 that conquered Le Mans half a century ago, and through the previous Ford GT that debuted a decade ago. Both of those featured V8 engines (supercharged in the latter case) while their modern successor goes with a twin-turbo V6. But as Xcar points out, six cylinders aren't without their precedence in the history of the GT-series Ford supercar: the GT70 rally car of 1970 originally packed a 2.6-liter V6. That engine was later replaced by a 1.6-liter inline-four, which puts another crack in the theory of the eight's hegemony over the history of the series – as does, we'll point out, the Bugatti-like quad-turbo V12 that featured in the GT90 concept of 1995 that sadly never made production. The point is that divergence from V8 tradition shouldn't dissuade anyone from getting excited over the arrival of the new GT, and we're looking forward to seeing what she can do – on and off the track.

Ford recalls 277,000 Super Duty trucks over foggy rear-view camera

Ford has issued a recall that applies to around 277,000 units of the Super Duty pickup built between the 2017 and 2020 model years. The campaign also includes about 13,000 units of the Lincoln Continental, and it aims to fix an issue that makes the rear-view camera foggy. Assigned recall number 22V-644 by the National Highway Traffic Safety Administration (NHTSA), the recall includes 139,131 units of the F-250, 109,960 units of the F-350, 14,830 units of the F-450, and 13,119 units of the Continental. The affected trucks are all fitted with the Ultimate Trailer Tow Camera system and were built between November 12, 2015, and March 10, 2020, while the affected Lincoln models are equipped with the 360-degree camera and were made from November 30, 2015 to March 10, 2020.  Ford explains "degradation of the coating on an internal rear-view camera lens can lead to a progressively foggy or cloudy image." It adds ultraviolet radiation causes the problem and that this issue increases the risk of an accident, though it's not aware of accidents or injuries. Owners of affected cars and trucks who have already paid to get the issue fixed have until September 30, 2022, to ask Ford for a refund. The company will begin notifying customers about the recall by mail on September 12, 2022, and it will ask them to take their vehicle to the nearest authorized dealer to get the rear-view camera replaced free of charge.
