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.

Question of the Day: Most degraded car name?

When Ford came up with a not-so-sporty version of the Pinto and slapped Mustang badges on it in 1974, that was a low point for the Mustang name. When Chrysler applied the venerable Town & Country name on perfectly functional but unglamorous minivans, it saddened many of us. But perhaps the biggest demotion for a once-proud model came when, in 1988, General Motors imported a misery-enhancing Daewoo from Korea and called it the Pontiac LeMans. The original Pontiac LeMans was a great-looking midsize car with fairly advanced (for the time) suspension design and engine options including potent V8s and a screaming overhead-cam straight-six. The Daewoo-based Pontiac LeMans was a cramped, shoddy hooptie that served only to ruin the LeMans name forever, while stealing sales from the Suzuki-based Chevrolet Sprint. Sure, using the once-respected Monterey name on the Mercurized Ford Freestar was bad, but Mercury didn't have long to live at that point. I say the downward spiral of the LeMans name was the most agonizing in automotive history. What do you think? Related Video: This content is hosted by a third party.

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.
