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 delays North American production restart from coronavirus lockdown

Ford said on Tuesday it was postponing its plan to restart production at its North American plants due to safety concerns for its workers amid the coronavirus pandemic. To generate cash, the No. 2 U.S. automaker had said last week it was poised to restart production at some plants in North America as early as April 6, bringing back such profitable vehicles as its top-selling F-150 full-sized pickup, the Transit commercial van and SUVs. But on Tuesday, Ford said it had been aiming to resume production at several key U.S. plants on April 14, but would now instead do so at dates it would announce later on. "The health and safety of our workforce, dealers, customers, partners and communities remains our highest priority," Kumar Galhotra, president of Ford's North American operations, said in a statement. Still, the automaker will open a plant in Ypsilanti, Michigan, during the week of April 20, that will make ventilators to treat patients afflicted by the coronavirus. Rival Fiat Chrysler Automobiles said last week it plans to resume production in North America on April 13. General Motors has shuttered its plants indefinitely and has not provided a date for vehicle production to restart. It is facing a delay in the production launch of its redesigned large SUVs and is delaying work on other SUVs. "Once it is safe to resume production, we will do so," a GM spokesman said. As of Monday, Volkswagen was shooting for an April 5 reopening at its Tennessee plant. Honda, Nissan and Subaru facilities in North America will remain closed through April 6, and Hyundai through April 10. Toyota was planning to reopen its North American plants April 17.

How Ford switched gears for the all-new F-150

Editor's Note: This story is authored by Julia Halewicz, a senior editor with AOL's Custom Solutions Group. She holds a Masters in Journalism from NYU and has spent her career as an editor of various newspapers, magazines and digital outlets. Last year on the Friday before Labor Day, the 2014 Ford F-150 pickup truck came off the Dearborn assembly line for the last time. After the last seam was welded, the F-150 that had been so beloved by American consumers would begin the transition from traditional steel manufacturing to an aluminum body, and the second phase of Ford's 2007 blueprint for sustainability would begin. Jobs would be created, and Ford would deliver a stronger product to its consumers. It was a moment Ford would call the biggest in the company's 111-year history. Breaking The Mold For some, the change was almost unfathomable. How could a truck be made with aluminum, and why change what clearly was working very well for the company? "We have a saying at Ford that leaders lead," said Doug Scott, the company's truck group marketing manager. "This was an ideal product to make with aluminum-alloy, because lightweighting made so much sense for a truck, because the extent to which you could take weight out of a truck, you could add more value to the customer in terms of more towing, more payload, more durability, more efficiency – so again all this required us to be out in front further out in front that we normally would be to make sure that we would deliver on all those expectations." Ford began the planning process about five years before the first aluminum F-150 would come to market. The company had a lot of questions. What was customer acceptance of aluminum, could they build the truck, and could the truck be repaired out in the field? Finally, Ford needed to determine if there were enough materials available to support the demand for the F-Series. Aluminum vehicles aren't unusual, but had never been built on the scale of the F-150 – approximately one every minute. Ford created two prototypes to determine if the product would meet and exceed consumer expectations. Any change to the vehicle had to be justified in performance, safety and economy. An aluminum truck needed to be safer, lighter, have increased payload, haul more, and have improved fuel efficiency. After driving the prototypes, Ford knew it was ready to move forward. Once the aluminum truck was ready to build, the next challenge was quickly transforming the plant.
