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 recalls 2017 Lincoln Continental for headlight problem

Ford Motor Co. is already recalling the 2017 Lincoln Continental for a headlight problem, the automaker announced Tuesday. The HID headlights may have been assembled with LED lens that don't have the correct lens optics to meet federal visibility requirements for turn signals. Ford says it is unaware of any accidents related to the issue. The company will replace the headlamp assemblies, if needed. The safety compliance recall covers 1,876 Continentals built from June 14 to Sept. 23 at Ford's Flat Rock factory south of Detroit. Most of the cars are in the United States; 49 are in Canada, and one is in a federalized territory. Only about 300 cars are in consumers' hands, a spokesperson said. Customers can use a Lincoln service program where dealers will pick up their Continental, fix it for free, and return it, the spokesperson said. Lincoln has high hopes for the Continental. The flagship sedan uses one of Lincoln's most iconic names and features a luxurious interior, available 400-horsepower V6 engine, and safety features like adaptive cruise control and a 360-degree camera. Lincoln recently announced an elaborate marketing campaign shot by renown photographer Annie Leibovitz to generate interest in the Continental. In a separate recall, Ford also said Tuesday that 60 Edges from the 2015-16 model year are being recalled to update their antilock braking system module.

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.
