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.

Leno drives Henry Ford II's all-original '52 Ferrari 212 Barchetta

The story of the relationship between Henry Ford II and Enzo Ferrari is absolutely fascinating. The two great men of the auto industry had what appeared to be a burgeoning friendship until Ferrari pulled out of a deal to sell his company to Ford in the '60s. The latest car featured in Jay Leno's Garage is a 1952 Ferrari 212 Barchetta that tells the very beginnings of that story.
This Prancing Horse was a gift to Ford from Enzo when the two companies were first thinking about merging, according to the curator of the Petersen Automotive Museum. Ferrari really wanted to show off its best so instead of the 212's normal V12, this car was fitted with the larger 2.7-liter unit from a Ferrari 225. The car has been almost unaltered since then. It still wears its original paint, and it's tires date back to 1954.
The great thing about the Petersen is that unlike a lot of auto museums, the people there actually drive the cars and keep them in working order. Once on the road with Leno behind the wheel, this Ferrari really sings. Unfortunately, he can't open it up too much because the 60-year-old tires really hold things back. Scroll down to watch this amazing piece of automotive history and learn it's possible effect on the styling of the original Ford Thunderbird.

Ford F-150 pulls semi truck through snow-clogged Chicago streets

Earlier this week, the Midwest was crippled by a massive snowstorm that dumped a foot or more of powder in some areas. The result was, of course, transportation gridlock. It's a fortunate thing for this stranded semi-truck driver, then, that a Ford F-150 EcoBoost stumbled upon him. Despite a tow rating of just over 11,000 pounds, the four-wheel-drive, turbocharged pickup managed to dislodge the big rig from a snow-covered street. Of course, the Ford didn't get the semi moving all on its own – watch the video towards the end and the semi was quite clearly spinning its rear tires. Still, it's an impressive feat that we've little doubt F-Series fans are celebrating. Related video:
