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.

Junkyard Gem: 1993 Mercury Topaz GS Sedan

As long as the Mercury brand existed — a period spanning the 1939 through 2011 model years — nearly every Mercury sold in the United States was more or less a redecorated Ford model. The Torino had its Montego sibling, the Crown Victoria had the Grand Marquis, the Cougar was based on everything from the Mustang to the Mondeo, and so on. Naturally, when the folks in Dearborn developed the Ford Tempo compact, a Mercury version had to be created. This was the Topaz, with the official launch of both cars taking place on the deck of the aircraft carrier often referred to as the USS Decrepit. You can't make this stuff up! The Tempo/Topaz, also known as the Tempaz, has largely faded from our collective automotive memory by now, since it broke no significant new engineering or styling ground (this story would be much different if Ford had only put the amazing straight-eight "T-Drive" Tempaz powertrain into production) and didn't have any endearing features other than being a cheap domestic competitor to the Toyota Corolla and Nissan Sentra. Still, close to 3 million Tempazes left North American Ford and Lincoln-Mercury showrooms during the 1984-1994 period. As you'd expect, most of these disposable cars disappeared from both the street and the car graveyard long ago. It takes a very special Tempaz for me to break out my camera while I'm patrolling my local wrecking yards; generally, this means an ultra-rare all-wheel-drive version or at least a very early model in super-clean condition. Today's Junkyard Gem is neither, but I took one look at this spectacular Bordello Red crypto-velour-and-slippery-plastic interior and recognized that this was no ordinary junkyard Mercury. It appears that Mercury had dropped the idea of clever names for base-grade seat fabrics by the time of the Topaz, referring to this stuff as just "cloth" in all the brochures I could find. That's too bad, because Mercurys had cool names for upholstery (e.g., Chromatex) in the old days. The interior is in very good condition but the steering wheel shows substantial wear, so I think this is a high-mile Topaz that got meticulous care from its owner or owners. Ford used five-digit odometers on these cars until the end of production, however, so we'll never know if this reading indicates 65,404 miles or 365,404 miles. The body is very straight, but there's some nasty corrosion behind the right front wheelwell.

2023 Grand National Roadster Show Mega Photo Gallery | Hot rod heaven

POMONA, Calif. — From an outsider's perspective, it would be easy to assume that the Grand National Roadster Show has always been a Southern California institution. After all, it celebrates the diverse postwar car culture of the region — hot rods, lead sleds, lowriders, and more. However, the show had its roots in NorCal in 1950 when Al Slonaker and his hot rod club showed their custom cars at the Oakland Expo. The GNRS moved to Pomona, California, in 2004. By then it had grown exponentially and seen about a dozen more car customization trends come and go. However, the show and its centerpiece award, the America's Most Beautiful Roadster prize, celebrate what is perhaps the first of those trends: the American hot rod in its purest form. Today, in its 73rd year, the GNRS is the oldest indoor car show in America. Annually it welcomes 500-800 cars, gathered into special themes like Tri-Five Chevys or Volkswagen Bugs. At this year's show, which was last weekend, a special hall was dedicated to pickup trucks built between 1948-98, including mini-trucks, groovy camper bed conversions, and resto-mods.  However, of all the vehicles presented, only nine are eligible for the America's Most Beautiful Roadster award. Winners get their names engraved on a 9-foot-tall perpetual trophy that was, according to The Ultimate Hot Rod Dictionary, the largest in the world when it debuted in 1950. Slonaker chose the word "roadster" initially because "hot rod" bore slightly negative outlaw connotations in 1950. Only American cars built before 1937 of certain body styles — roadsters, roadster pickups, phaetons, touring cars — are eligible, and they cannot have roll-down side windows.  Cars in the running for the cup cannot have been shown anywhere else before their debut at the GNRS.  Contestants for this accolade essentially build their cars to the a platonic ideal of a hot rod. This year the honors went to Jack Chisenhall of San Antonio, Texas, for his "Champ Deuce," a 1932 Ford Roadster. It's exactly what you picture when you think of a hot rod, but distilled to its absolute essence.  Other standouts included "Green Eyes," a two-tone green 1959 Chevy El Camino  with a heavily metal-flaked bed, "Blue Monday," a 1964 Buick Riviera lowrider, and a personal favorite, "Purple Reign," a purple and black 1951 Mercury. Cars may have started out as tools, but there aren't shows like this filled with custom refrigerators.
