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: 1973 Mercury Marquis Brougham 4-Door Pillared Hardtop

Ford's Mercury Division debuted the Marquis in the 1967 model year, as a sporty coupe based on a stretched Ford LTD chassis. When the LTD got an update for 1969, so did the Marquis, and production of that generation of the top-of-the-line Mercury continued through 1978 (the Grand Marquis hit streets the following year). The 1969-1978 Marquis was a big, imposing land yacht, and the Brougham version came absolutely loaded with affordable luxury. Today's Junkyard Gem is a Marquis Brougham from the first year of the Malaise Era, found in a Phoenix self-service car graveyard recently. This car appears to have spent decades sitting outdoors in one of the harshest climates in the country, and so it's in rough shape. The vinyl top received the full thermonuclear treatment and is mostly obliterated by now. The interior got thoroughly cooked as well. Still, its original opulence shines through if you use some imagination. What hurts is that this car was packed with most of the good options, including the mighty 460-cubic-inch (7.5-liter) V8 engine with four-barrel carburetor. The price for the 460 was just $76 in this car, or around $548 in today's money. The base engine was a 429 (7.0-liter). Power numbers were way down for 1973 when compared to a couple of years earlier, partly as the result of tightening emissions standards but mostly due to the switch from gross to net power ratings that began midway during 1971 and was completed by the end of 1972. This engine was rated at 202 horsepower and 330 pound-feet. The only transmission available was a three-speed automatic. We can assume that the original buyer of this car and its single-digit fuel economy had a rough time when the OPEC oil embargo hit in the fall of 1973. Believe it or not, air conditioning was not standard equipment on the '73 Marquis Brougham (you had to move up to a Lincoln for that). This one even has the automatic temperature control feature, adding a total of $508 to the cost of this car (about $3,661 in 2023 dollars). That AM/FM/8-track radio—or, in fact, any radio—was an extra-cost option as well, with a price tag of $363 ($2,616 after inflation). The MSRP for the 1973 Marquis Brougham sedan (known as a "pillared hardtop" thanks to the frameless window glass) was $5,072, which comes to $36,555 in today's dollars. Obviously, its out-the-door cost would have been much higher with all the options.

NHTSA investigating 725k Ford, Mercury vehicles for stalling issue

Owners of Ford Escape, Mercury Mariner, Ford Fusion and Mercury Milan models, listen up. According to a report on Automotive News, the National Highway Traffic Safety Administration has opened an investigation into these four vehicles totaling an estimated 725,000 units. The investigation appears to center around a malfunctioning throttle body on non-hybrid models of the 2005-2012 Escape and 2011-2012 Fusion. With Mercury dying off after the 2011 model year, this probe will also apply to the 2005 through 2011 Mariner and the 2011 Milan. There has been some discussion around the Escape stalling issue for some time now, but this investigation appears to be larger in scope than before.
Though not a recall yet, NHTSA's Office of Defects Investigation (ODI) has received 123 complaints of stalling or surging vehicles, while Ford itself has logged 1,472 complaints. The investigation report, which is posted below, seems to indicate that a faulty circuit board for the throttle body could cause the vehicle to go into limp mode, which, according to NHTSA, could cause complaints of both stalling and surging.
