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.

Lincoln Continental to end after one-and-done generation?

After only 18 months on sale, the vultures of rumor have begun circling above the Lincoln Continental. Ford Authority says "sources intricately familiar with Ford Motor Company's future product plans" for the domestic luxury brand say the Continental won't get another chance at life after this generation. Those sources didn't detail Ford's reasons for dispatching the executioner on another sad task, but if this is true, even the reasons we can only guess make enough sense to justify the move. The Continental launched into a crossover mania still mushrooming in strength like some Marvel villain, the equivalent of a new dinosaur hatching a few months before the Chicxulub Impact Event. In 18 months, the Continental sold 18,846 units, 12,012 of those sales happening in 2017. In the U.S. this year, sales amounted to 1,573 units through February, about 25 percent down on the annualized monthly rate. It could be worse: The Lexus GS has found 1,009 U.S. buyers so far this year, the Acura RLX, 285. Conversely, the Cadillac XTS — yes, a fleet darling — secured 3,163 sales in the same period. And the German kingpins live in another dimension, with BMW scooting 5,641 5 Series models off dealer lots, and the Mercedes E-Class boasting 8,411 sales of all three variants. Even the much more expensive and much more profitable Lincoln Navigator rang up 2,351 sales in the first 60 days of 2018. That's disheartening reading, especially after Ford reportedly spent more than $1 billion to bring the Continental to market. Sedan segment woes look to have killed the Continental's platform siblings, too, making the Lincoln's demise simply part of the cull. The CD4 architecture also underpins the Ford Fusion and Lincoln MKZ. Ford canceled the Fusion redesign and won't commit to making either vehicle after 2020. Lincoln's passenger car sales declined more than 30 percent last month; meanwhile, Lincoln needs to spend its money on the crossovers that are selling, and investment in the coming three-row Aviator that will replace the MKT. Ford has a CD6 platform in development that suits front-, rear-, and all-wheel-drive vehicles. Under previous CEO Mark Fields, a new Fusion, Mustang, and MKZ would ride on the CD6, as well as the new Explorer and a Lincoln brother. Those plans left with the previous administration, and company sources told both Ford Authority and The Truth About Cars not to expect a Continental revival on that architecture. Related Video:

Ford recalling 126,000 Fusions and Milans over wheel separation concern

Ford has announced a recall of certain Ford Fusion and Mercury Milan vehicles after an investigation by the National Highway Traffic Safety Administration. A total of 128,616 2010 and 2011 models equipped with steel wheels may have been manufactured with wheel studs that could crack and split over time. If that happens, the vehicle may experience a wheel separation.
According to The Detroit News, the company is aware of a total of 30 wheel separation incidents, one of which occurred on the front of the vehicle. Even so, no injuries have been reported as a result of the defect.
The problem apparently stems from the fact that the mounting pads on the vehicles' steel wheels may have been faulty from the factory. In addition, the wheel mounting face on rear disc brakes may not have been installed properly. Ford will inspect the rear disc face and replace them as necessary. In addition, the company will replace all of the vehicle's wheel studs free of charge. Head to the NHTSA website for more information, and click past the jump to view the full recall notice.
