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 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.

What's in a trademark? Sometimes, the next iconic car name

The United States Patent and Trademark Office is a treasure trove for auto enthusiasts, especially those who double as conspiracy theorists.
Why has Toyota applied to trademark "Supra," the name of one of its legendary sports cars, even though it hasn't sold one in the United States in 16 years? Why would General Motors continue to register "Chevelle" long after one of the most famous American muscle cars hit the end of the road? And what could Chrysler possibly do with the rights to "313," the area code for Detroit?
