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.

USPS releases hot rod stamps to speed up your delivery

After one of the worst winters in recent memory for much of the country, summer is finally here. It's time to drop the top, open the sunroof or at least put down the windows and take a long drive. The United States Postal Service is celebrating the season's sun in automotive style with two new hot rod Forever stamps.
Both stamps depict classic '32 Ford hot rods. One shows the car from the front at a low angle in red (pictured above), while the other depicts the car from the back in black with flames running down the side.
To introduce the new stamps on their first day of availability, the USPS went straight to the source at the National Street Rod Association Street Rod Nationals in York, PA. They were unveiled by Postmaster General Patrick Donahoe, Car Crazy host Barry Meguiar and NSRA Special Events Director Jerry Kennedy.

Ford profits soar as problems mount

Ford is doing well. It can't make enough examples of its new Fusion, it can barely make enough of the aging F-150, it's getting good brand rankings, people like its turnaround story, it's selling oodles of product and its quarterly profit numbers end in the word "billion." As other high-flying examples have demonstrated over the past few years, though, big numbers can come with problems that aren't exactly small.
Automotive News has published a good "nutshell" report of Ford's progress and problems. The Dearborn automaker's optimistic "general label rule" determination of gas mileage for the C-Max Hybrid has led to lawsuits, hybrid software updates, a downward revision of C-Max fuel economy and millions in rebates. AN notes the C-Max was the "worst-scoring model in this year's J.D. Power Initial Quality Study," but Ford will probably be happy that it managed not to be mentioned further in the study's results after last year's mediocre showing. Its MyTouch and SYNC systems, the bugbears sabotaging Ford's J.D. Power results, have also led to lawsuits, software updates, more software updates and a center console rethink. On top of that, the 1.6-liter EcoBoost in the 2013 Ford Escape that Ford called a "hero" was soon catching fire for three different reasons. And let's not even get into the troubled launch of the Lincoln MKZ.
The Automotive News piece notes that industry observers have been surprised at Ford's stumbles because everything has been looking so good. Nevertheless, there is still the issue of those billions in profits - the company is doing plenty of things, plural, right. Ford says it is tackling its problems, hiring engineers and instituting new quality control processes as part of its effort to find solutions. The test will be to see if in a year from now we begin the discussion of these issues with "Remember when Ford...", or "Problems continue at The Blue Oval."
