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 CEO Jim Hackett reviewing the future of technology, Lincoln, overseas markets

By Paul Lienert and Joseph White Ford Chief Executive Jim Hackett is reviewing the automaker's operations in India and other markets, as well as Ford's future product programs including plans to build a self-driving commercial vehicle in 2021. Hackett, who took over as CEO in May, has told investors he is working on a 100-day review of Ford's operations but has so far provided few details of the process, except to indicate that it is looking at the automakers' luxury vehicle strategy, the future of its small vehicles and investments in emerging markets. Ford Chief Financial Officer Bob Shanks told Reuters in an interview that the review covers a range of issues, including Ford's strategy for India. "We have a lot of work to do (as) we address issues of how to fix India," Shanks said. "Everything is on the table." General Motors in May said it would stop selling cars in India but continue to produce vehicles there for export. Shanks said no decisions have been made and noted that Ford has a larger business in India than GM did. "We are very cognizant that will be the third-largest market in the world," he said. "Some big decisions will be made," Shanks said, but he cautioned Ford may not disclose all those decisions at the end of the 100-day review. Hackett is addressing challenges that have contributed to a nearly 8 percent decline in Ford's share price this year. The review of the Lincoln luxury brand includes whether current plans will meet former CEO Mark Fields' ambitious targets for growth and revenue, people familiar with the process said. Ford has set a target of putting a self-driving shuttle into commercial ride-sharing fleets by 2021. Hackett is reviewing the investment and timing for that project, the sources said. Hackett also assessing whether to reduce and consolidate production of models such as the Fiesta subcompact and two midsized sedans that are built in multiple locations around the world, but are experiencing slowing demand. One proposal would shift production of the next-generation Mondeo midsized sedan from Europe to Mexico, where it would share an assembly line with its sibling, the Ford Fusion, avoiding the cost of retooling two plants. Shortly after he took charge, Hackett approved a proposal to shift production of the next-generation Focus for North America from Mexico to China, saving the company an estimated $500 million by consolidating two factories into one.
