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: 1979 Mercury Marquis 2-Door Sedan

As the creator of the now-much-overused term "Malaise Era" (which I say started in 1973 and ended in 1983, full stop), I have a certain affection for the big two-door Detroit cars of the late 1970s. When such a car is built on the very first model year of Ford's long-lived Panther platform and I find one in a junkyard, I must document it. The 1979 Mercury Marquis is such a car, and this one was found in a San Francisco Bay Area self-service yard last month. Since Ford built the Grand Marquis all the way through the demise of the Panther platform— and Mercury itself— in 2011, it's easy for us to forget that the model name started out as just the plain old Marquis, back in the 1967 model year, with the Grand appellation used for the car's top trim level. While today's Junkyard Gem has some of the features of the Grand Marquis and Marquis Brougham trim levels for 1979 (notably the padded vinyl landau roof and power windows), it lacks the huge chrome lower-body moldings of those cars. Instead, it's a regular Marquis 2-door sedan with a big load of expensive options. That landau roof has suffered greatly from its decades beneath the vinyl-disintegrating California sun. The Panther platform was a big technological upgrade from the late-1950s-vintage chassis technology of full-sized Fords of the 1960s and 1970s, and it stayed in front-line service in much the same form through 2011. Though its ride and handling were much improved, the 1979 Marquis was quite a bit smaller than its predecessors, and that caused some grumbling among Mercury shoppers. Some ham-handed junkyard shoppers really tore up the interior of this car while extracting a few bits and pieces, but we can still admire the Pine Green pleather of the glorious Twin Comfort Lounge front seats. You had two engine choices when buying a new '79 Marquis: the base 302-cubic-inch (5.0-liter) Windsor V8 making 129 horsepower or the optional 351-cubic-inch (5.8-liter) Windsor V8 rated at 138 horsepower. This one appears to be the 351, the same engine as had been swapped into the pizza-delivery Mercury I drove in the middle 1980s. New cars sold in California around this time had these giant emissions-numbers stickers on the side glass. Later, they went on the underside of the hood.

Junkyard Gem: 1995 Mercury Tracer Trio

With the rise of Radwood, cars with exaggerated characteristics associated with the 1980s and 1990s are cool again. That means some combination of pastel and/or neon colors, squiggly squeezed-from-toothpaste-tube graphics, nonfunctional decklid spoilers, giant TURBO badging, and kicky youth-centric nomenclature are required if you want your wheels to be considered in compliance with the sacred tenets of Radism. I do my best to find rad machinery while crawling around in car graveyards, and since I came of driving age in 1982 I know a bit about the subject. Today's rare Junkyard Gem shows us the Mercury Division's belated attempt to sell fun cars to rad-leaning youngsters: a Tracer Trio, found in a Denver yard a few weeks back. The Trio package added 310 bucks to the cost of the $11,280 base Tracer sedan (that's about $575 on a $20,925 car in 2022 dollars), and it got the hip-and-trendy young buyer a leather-wrapped steering wheel, seven-spoke wheels, a decklid spoiler and these rad fender badges. I'm going to say that the much louder graphics and candy-cane-colored displacement badges on the Pontiac Sunbird W25 out-radded the Tracer Trio by a mile, but then Pontiac generally out-radded everyone in those days. Even Plymouth got into the act with such radness as the Breeze Expresso and Sundance Duster (we'll overlook the anti-rad Horizon Miser here). Perhaps tellingly, Mercury, Pontiac and Plymouth all got the "Old Yeller" treatment not long after the Rad Era ended. The Tracer name always went on Mercuries built on Mazda platforms, starting with the Australia-built, Ford Laser-based 1987-1989 cars and then continuing with Mexico-assembled, Ford Escort-based 1991-1996 cars. That generation of Escort/Tracer was mechanical twins with the Mazda Protege, itself the bridge between the 323 and the Mazda3. Some Tracers got the a 1.8-liter Mazda engine that was related to the Miata's engine, but this one has the pure-Detroit CVH 1.9. You're looking at 88 horsepower right here; the Mazda 1.8 offered 127 horses. At least the original buyer of this car got the base five-speed manual transmission instead of forking over $815 extra (about $1,510 today) for the four-speed slushbox. As a 29-year-old slacker living in San Francisco's Mission District and driving a hooptie '65 Chevy Impala sedan at the time, I would have taken the manual transmission without the Trio package, had I been forced to buy a new Tracer.
