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.

V6 engines will outpace V8s for the 2015 Ford F-150

How times have changed. Even five years ago, who would have thought the mighty V8 would be just another engine choice for buyers of the 2015 Ford F-150?
Ford is projecting about 28 percent of the next-generation trucks will have the 5.0-liter V8. That's nothing to sneeze at, but consider this: Ford figures its two EcoBoost truck engines - the new 2.7-liter V6 and the existing 3.5-liter V6 - will also each account for about 28 percent of the F-150's sales (56 percent total). That leaves only 15 percent of the pie for the 3.5-liter (non-EcoBoost) V6. The new F-150 goes on sale late this year.

Ford and Chrysler reducing summer plant shutdowns

Most domestic automaker assembly plants traditionally take a couple of weeks off during the summer. The shutdowns give each plant time for much needed repairs and maintenance, and in some cases, help better align production with demand. Not this year, though, as demand for many models is outstripping what Ford, Chrysler and General Motors plants can produce.
Ford has announced that it will shorten its annual summer shutdown for most North American plants from two weeks to one. The shorter shutdown will increase the carmaker's annual North American production by 40,000 units on top of the 200,000 extra units that it was already planning to produce this year versus last. Automotive News reports that Ford produced 2.8 million vehicles on this continent in 2012, and that output this year has already increased 13 percent through April.
Chrysler, meanwhile, is also operating at full tilt and plans to run some plants through the summer with no shutdown at all. Those not getting a break include Jefferson North where the Jeep Grand Cherokee and Dodge Durango are assembled, Toledo North that will assemble the new Cherokee, and Conner Avenue, home of SRT Viper production. Other assembly plants will be down for a single week, while all of Chrysler's engine and transmission plants except one in Indiana will continue operating with no shutdown this summer.
