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 builds Lightweight Concept with Fusion shell [w/video]

It's a fairly well known fact that removing weight from a car is essentially a panacea for many of the modern automobiles problems. Does it handle like crap? Remove weight. Underpowered? Don't add power; trim the fat. Need to improve fuel economy? It's diet time.
Actually executing a major weight reduction program, though, much like with human beings, is no easy task. Unlike you or I, where motivation is the issue, the prohibitive measure in trimming a car's waistline is money. Lightweight materials are expensive, with carbon fiber and carbon-fiber reinforced plastic still primarily in the domain of higher end vehicles. Even aluminum construction, pioneered on a mass-produced level by Audi and Jaguar, is only now starting to make its way into the mainstream, thanks to the upcoming Ford F-150.
With this concept, though, Ford is attempting to show that a mass-produced, lightweight vehicle isn't too far off. This is the Lightweight Concept, and while it may look like a Fusion, it weighs as much as a Fiesta. For reference, the lightest Fusion available to the public is the 3,323-pound, 2.5-liter model with a manual transmission. A manually equipped, 1.6-liter Fiesta, meanwhile, is just 2,537 pounds.

FCA to skip summer shutdowns as automakers rev up U.S. assembly lines

DETROIT — Several of FCA's facilities will skip their usual summer shutdowns to get a jump on rebuilding inventory, the company confirmed early Wednesday.  The plants that will remain open include three in the United States (Jefferson North in Detroit, Toledo Assembly in Ohio, and Sterling Heights Assembly in suburban Detroit), one in Canada (Brampton Assembly in Ontario) and two in Mexico (Saltillo Truck Assembly and Saltillo Van Assembly).  This will allow dealers to address depleted inventory of popular trucks and muscle cars, Automotive News reports. Other facilities not named will observe their normal one- and two-week breaks.  Automakers are speeding up U.S. assembly lines to meet recovering demand, increasingly confident coronavirus safety protocols are working to prevent outbreaks in their plants but wary of the challenges workers face outside. Screening workers for COVID-19 using temperature scans and questionnaires, the automakers have detected some people who reported for work despite being sick. Some plants have been briefly shut down for disinfection, but so far, there has not been a major outbreak within a U.S. auto plant since most reopened May 18, company and United Auto Workers union officials said. The risk of an infection picked up outside a plant spreading along assembly lines remains a prime concern, however. An outbreak could shut down a factory costing a manufacturer millions of dollars a day. The disruption caused by the pandemic is creating other challenges as well. At Ford Motor Co's F-series pickup truck plant in Louisville, Kentucky, the company has given more than 1,000 workers leave related to COVID-19 concerns. It hired temporary workers to fill their jobs as the plant accelerates production of trucks critical to Ford's financial recovery. Demand for pickup trucks helped boost U.S. auto sales in May, and contributed to stronger than expected overall U.S. retail sales for the month. Officials of UAW Local 862, which represents workers at the Louisville plant, said a lack of child care was a significant issue for members. It had led many to stay away from the plant and collect increased unemployment benefits provided under the federal CARES coronavirus relief act. Ford has now begun arranging subsidized child care for UAW workers, Gary Johnson, the automaker's head of manufacturing told Reuters.
