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.

Join Autoblog editors for a full video tour of the 2019 Detroit Auto Show

The 2019 North American International Auto Show might have been a little more quiet than past years, but there were still some pretty major reveals, including the Toyota Supra, new Ford Explorer, Shelby GT500, Subaru WRX STI S209 and Kia Telluride. We also saw some lovely concepts like the Nissan IMs and Lexus LC Convertible. Senior Editor Alex Kierstein, Consumer Editor Jeremy Korzeniewski and Senior Green Editor John Beltz Snyder join me, Associate Editor Reese Counts — with Social Media Manager Michael Dylan Ferrara behind the camera — on a long walk through the show. We discuss cars, poke around the stands, dress a bloody wound and answer your questions in the Facebook comments.

Second-tier UAW workers promoted for first time after Ford hits quota

The United Auto Workers put out a statement on Friday that 55 Ford workers chosen by seniority would be moved from the Tier 2, entry-level pay rate of around $19 per hour to the Tier 1, non-entry-level rate of about $28 per hour. One of the stipulations in the 2011 UAW-Ford agreement was that only 20-percent of the total hourly workforce could be paid the Tier 2 wages agreed upon in 2007; after that, those workers had to be moved to Tier 1. Even so, the new Tier 1 status makes them less expensive to Ford than veteran Tier 1 workers because they receive fewer benefits. However, Automotive News had reported that same day that Ford was 69 workers shy of the limit, and when AN asked Ford about the situation Ford said it had "some room" on the entry-level roster. If workers do move to the higher pay grade, it will be the first time that's happened since the two-tier system was agreed. But it sounds like there's going to be some haggling between the UAW and Ford before that happens. Ford is the only one of the Detroit 3 automakers to have to work with a cap, since it didn't go through bankruptcy proceedings during The Great Recession; General Motors and Chrysler jettisoned the cap in 2009. GM is said to have 16 percent of its hourly workers at Tier 2 while Chrysler has 42 percent, but Fiat-Chrysler CEO Sergio Marchionne has long been opposed to the two-wage system. The UAW is preparing for its 2015 negotiations with the US automakers. It wants to eliminate the difference in pay by going to the higher scale, if there is a consensus among automakers it seems to be that they also want a single wage, but less than the higher scale, with the addition of profit-based bonuses. The recent statement from the labor union is below. UAW President Dennis Williams and UAW-Ford Vice President Jimmy Settles announced today that the union is delivering on its promise to convert workers DETROIT, Jan. 30, 2015 /PRNewswire/ -- UAW President Dennis Williams and UAW-Ford Vice President Jimmy Settles announced today that the union is delivering on its promise to convert workers making entry-level wages to traditional employees. "The 2011 UAW-Ford agreement allows for a contractual limit of entry-level employees. Once that threshold is surpassed, entry-level employees convert by seniority to 'regular, non-entry level employment.' At this time, fifty-five UAW-Ford workers will receive the wage increases, which put them in the category of non entry-level employment.
