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: 1981 Mercury Cougar XR-7

The story of the Mercury Cougar involves more plot twists and unexpected digressions than that of just about any other Detroit car, with successive Cougar generations based on the Ford Mustang (1967-1973), the Ford Torino and/or Thunderbird (1974-1979), various Fox Fords including the Thunderbird (1980-1988), the MN12 Thunderbird/Lincoln Mark VIII (1989-1997), and the Ford Mondeo (1999-2002). There were wagon and sedan Cougars for brief periods, just to confuse everybody, and the rakish XR-7 Cougars sometimes lived on different platforms from their ordinary non-XR-7 counterparts. I think the Late Malaise Era Fox XR-7s are among the most interesting of the bunch, so I was quite excited to spot this tan-over-gold '81 in a Denver yard. I tried to count the number of screaming-cat badges on and in this car and gave up once I hit a dozen. The steering wheel, door panels, C pillars, center console, and — of course — the hood ornament all boast snarling felines. Earlier Cougars had emblems showing full side views of stalking catamounts, but the Cougar logo for the 1980s showed just the head. This car got the optional center console, which I hear is quite a rarity. You had to pay $174 extra (that's around $513 in 2020 dollars) for an AM/FM/cassette audio system in the '81 Cougar, but at least the air conditioning was standard equipment. Believe it or not, thieves used to steal these radios. Kumpf Lincoln-Mercury still exists in Englewood (as Landmark Lincoln), and the yard that now houses this car can be found just 15 miles up Broadway on the north side of Denver.  The padded landau roof hasn't fared so well beneath the fierce Colorado sun, but overall this car seems very solid. Sadly, only the Mustangs and (once in a long while) Fairmonts get much love from the Fox Ford crowd these days. Three Mercury "wire wheel" hubcaps and one from a Lincoln. The base engine in the 1981 XR-7 was the "Thriftmaster" 200-cubic-inch (3.3-liter) straight-six, but very few XR-7 buyers would have refrained from checking the box for one of the two optional Windsor V8s. I can't tell if we're looking at the 255-cubic-inch (4.2-liter) version or the 302-cubic-inch (5.0-liter) one here, but real-world drivers might not have noticed the difference between the 120-horse 255 and the 130-horse 302, anyway. The non-XR-7 Fox Cougars had five-speed manual transmissions as base equipment (which nobody wanted), but all 1981 XR-7s had automatics.

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.
