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.

Detroit automakers observing 8:46 of silence to mark Juneteenth

GM Executive Vice President of Global Manufacturing Gerald Johnson, right, talks with employees at the Fairfax Assembly & Stamping Plant in Kansas City, Kansas. (file photo - GM)     All three Detroit automakers are observing Juneteenth, a day commemorating the end of slavery, on Friday by observing 8 minutes and 46 seconds of silence, among other companywide efforts to advance the causes of social and racial justice and equality. Juneteenth marks the date, June 19, in 1865 when Union soldiers, led by Maj. Gen. Gordon Granger, arrived at Galveston, Texas, and announced the Civil War had ended and enslaved African Americans were to be freed. President Abraham Lincoln had officially ended slavery more than two years prior via the Emancipation Proclamation, but Union forces didn't reach Texas until that time, so there was virtually no enforcement. The 8:46 timestamp is significant because it was the length of time that a police officer in Minneapolis knelt on the neck of George Floyd during an arrest, ultimately killing him and sparking waves of protests across the U.S. and overseas. Autoblog asked automakers about their plans to mark Juneteenth, what they were doing to advance the cause of social justice for Black people, and how many African Americans they employ in both blue- and white-collar jobs. We heard back from GM, Ford, Fiat Chrysler and Honda but not from Nissan and Toyota. General Motors GM’s U.S. workforce is 17.2% Black and 69.2% white, according to its most recent corporate Diversity and Inclusion Report. GM's total global employment is 173,000, and it says women and minorities represent 40% of its team of corporate officers. For reference, the Census Bureau says African Americans make up 13.4% of the U.S. population of roughly 328 million people. White people constitute 76.5%. As previously reported, GM planned to pause production at its factories on each shift today and observe silence for 8 minutes and 46 seconds. The company will also have a digital countdown clock atop the GM's headquarters in Detroit for the moment of silence. Additionally, Chairman and CEO Mary Barra has said she will lead a new Inclusion Advisory Board made up of people from within and outside GM to suggest areas for change and hold the company to its commitments to fight injustice and racial inequality.

Ford expands 'Do Not Drive' airbag warning to 33,000 more Ranger trucks

WASHINGTON — Ford on Monday warned an additional 33,000 owners of older pickup trucks in North America to stop driving them until potentially defective Takata Corp airbag inflators can be repaired. In January, Ford told 2,900 owners of model year 2006 Ford Ranger trucks to stop driving immediately after a second death was linked to inflators built on the same day. The expanded warning was prompted by additional testing, Ford, the second largest U.S. automaker, said in a statement, and now covers a broader time frame of production. Mazda Motor Corp said it was issuing a similar expansion for about 1,800 2006 Mazda B-Series trucks that were built by Ford after it had issued a warning for 160 trucks in January. The National Highway Traffic Safety Administration (NHTSA) said the vehicles pose "an immediate risk to safety" and urged owners to immediately schedule a free repair. Ford and Mazda have replacement airbag inflators available now and will tow vehicles to a dealership for repairs as well as provide loaner vehicles free of charge, the companies and NHTSA said. About 90 percent of the vehicles subject to the "Do Not Drive" warning are in the United States. Two U.S. senators in January questioned why Ford's warning only applied to a small number of the 391,000 2004-2006 Ranger trucks recalled because of Takata air bags in 2016 in the United States. Ford said last month the death in a July 2017 crash in West Virginia in a 2006 Ford Ranger was caused by a defective Takata inflator after a similar 2015 death in South Carolina. At least 22 deaths worldwide are linked to the Takata inflators that can rupture and send deadly metal fragments into the driver's body. The faulty inflators have led to the largest automotive recall in history. The other 20 deaths have occurred in Honda vehicles, most of which were in the United States. About a quarter of the 2,900 vehicles have been repaired since Ford issued the warning last month, the company said on Monday. Takata said in June it has recalled, or expected to recall, about 125 million vehicles worldwide by 2019, including more than 60 million in the United States. About 19 automakers worldwide are affected. Takata inflators can explode with excessive force, unleashing metal shrapnel inside cars and trucks and have injured more than 200 people. The defect led Takata to file for bankruptcy protection in June.Reporting by David ShepardsonRelated Video:
