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.

Lincoln recycling tree fibers into new MKX armrest

Want to hug a tree, or at least a really small part of one. Then set your arm down on one of those armrests in the 2014 Lincoln MKX crossover. The US automaker is working with Weyerhaeuser and Johnson Controls on a tree-based, cellulose-reinforced polypropylene material used in the component that connects the armrest to the floor console, Wards Auto says. With properties similar to plastic, the tree-based material replaces fiberglass and is about six percent lighter. No big deal for now, but if the material starts getting used for things like battery trays and interior storage covers, that loss in weight may eventually start adding up enough to boost fuel economy a bit, providing a green double bonus. Lincoln parent Ford, which isn't saying how much more (or less?) it costs to use the new material, established its Biomaterials and Plastics Research team in 2001. In 2007, the company began using soy-based foam in car seats used for models such as the Lincoln Navigator and Ford Mustang and has since broadened biomaterials use to components like floormats and cupholder inserts. Ford also used recycled plastic bottles from the 2012 North America International Auto Show for seats in the Focus Electric.

Ford shareholders happy as the Blue Oval stays in the black

Ford posted slightly falling global sales and revenue in its first-quarter financial announcement, but pre-tax profits and operating margins were up. Apparently, that was plenty to keep shareholders happy, though. The Blue Oval's recent investor meeting in Delaware lasted less than an hour, and a vote on the approval of the board passed by over 93 percent. Ford CEO Mark Fields continued to predict a strong year financially and increasing profits, according to the Detroit Free Press. The growth comes thanks in large part to the company's 24 global vehicle launches last year and 15 more this year. The likelihood of significant profits from the strong-selling 2015 F-150 should be especially lucrative, too. In the Q1 announcement, the Blue Oval forecast pre-tax profits between $8.5 billion and $9.5 billion for 2015. During the meeting, Fields said that the next 15 years of changes in the industry represent the "ultimate opportunity as a company. As big as when Henry Ford put the world on wheels more than 100 years ago," according to the Free Press. Investments like the expanded technology center in Silicon Valley should push that work along.
