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.

Hot sales have Detroit automakers shortening summer shutdowns

Back in May, there was speculation that the Detroit Three automakers would maintain or perhaps even extend their traditional summer shutdowns, mostly due to a bitingly cold winter that saw below-freezing temperatures infiltrate the southernmost reaches of the US, putting a chill on auto sales. Now, though, the numbers are in, and thanks to some promising sales figures, it looks like some domestic line workers are going to be working clear through July, in some cases.
According to Automotive News, Ford has slashed its traditional two-week hiatus for factory workers in half at four of its plants, while both Chrysler and General Motors will keep factories running nonstop (two plants in Chrysler's case and a third of GM's factories).
This is, as we said, thanks to some positive numbers. Chief among those is the Seasonal Adjusted Annual Rate, which was at an eight-year high of 17 million units. Individual figures were less promising. GM, embroiled in its recall scandal, still saw a one-percent increase while Ford dropped six percent in year-over-year sales. Chrysler was the big winner, though, with a nine-percent jump in June.

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.
