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: 1977 Mercury Bobcat

Cultural memory of the Ford Pinto, 38 years after the last new ones were sold, boils down to one thing today: the notorious "exploding Pinto" stories of the late 1970s. Yes, many Pinto jokes were told, the resale value of Pintos crashed, and few paid any attention to the fact that most of the cars sold with the fuel tank between the rear axle and the bumper — that is, just about every Detroit car made during the era — suffered from the same weakness. The Mercury version of the Pinto was badged as the Bobcat, but nobody told Bobcat jokes. Here's a '77 Mercury Bobcat 3-Door in vivid Medium Jade paint, spotted in a Denver self-service yard. The Pinto with glass rear hatch was known as the Pinto Runabout in 1977, while Mercury called this car the " Bobcat 3-door with Glass Third Door." When a car sits for years or decades in High Plains Colorado, rodents tend to nest in it. This Bobcat's air cleaner made a cozy home for our Hantavirus-carrying friends. The 1970s were the last gasp for eye-searingly green vinyl car interiors. Since the Bobcat was a luxed-up Pinto, the door panels have shinier trim than what you'd have had in a proletariat-grade Pinto. Pinto/Bobcat transmission choices boiled down to two: a four-speed manual or a three-speed automatic. Unusually for a Malaise Era Mercury, this one has the manual. Most Pintos and Bobcats came with four-cylinder engines, ranging from the 1.6-liter pushrod Kent to the 2.3-liter engine that lived on for many post-Pinto years in Ford Rangers. This car has the 2.3, rated at 89 horsepower, but the same 2.8-liter Cologne V6 that powered the Capri was available as an option in the Bobcat. That engine made a mighty 93 horsepower. These cars were not too miserable to drive by econobox standards of their time, at least when they had three pedals. You'd blow the doors off a '77 Corolla with a 4-speed Bobcat in a drag race, though the Corolla got better fuel economy. This content is hosted by a third party.
