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.

NHTSA advances investigation of Ford Crown Victoria headlights

The National Highway Traffic Safety Administration is opening a preliminary evaluation into reports of suddenly failing headlights on 517,945 examples of the 2003-2005 Ford Crown Victoria and Mercury Grand Marquis. The government started looking into this problem in April when the North Carolina Consumers Council filed a defect petition with the agency. Now, the inquiry has moved to the next step. According to NHTSA's documentation (as a PDF), it examined its own database and worked with Ford to come up with a total of 3,609 complaints of the front lighting control module suddenly failing. When this happens, drivers lose the low-beam headlights, but the high-beams can be used by holding the stalk. Sometimes turning the switch off and on fixes the issue. Additionally, there are 15 allegations of crashes, and one reported shoulder injury. NHTSA's preliminary evaluations "evaluate the scope, frequency, and consequence of the alleged defect" and don't necessarily lead to a recall. NHTSA looked into this problem once before in 2008 and 2009 and decided that a recall wasn't necessary. Ford also extended the warranty on the front lighting control module for these vehicles. INVESTIGATION Subject : Loss of headlights Date Investigation Opened: AUG 10, 2015 Date Investigation Closed: Open NHTSA Action Number: PE15028 Component(s): EXTERIOR LIGHTING All Products Associated with this Investigation Vehicle Make Model Model Year(s) FORD CROWN VICTORIA 2003-2005 MERCURY GRAND MARQUIS 2003-2005 Details Manufacturer: Ford Motor Company SUMMARY: After receiving a defect petition (DP15002) concerning the loss of headlights and other exterior lighting in model year (MY) 2003-2005 Ford Crown Victoria and Mercury Grand Marquis vehicles, the Office of Defects Investigation (ODI) analyzed Vehicle Owner Questionnaire (VOQ) complaints received from consumers and identified a total of 605 reports (for all submission dates) alleging headlight failure. The complaints indicate failures of both low beam headlights typically while driving, a defect condition that was evaluated under a prior ODI investigation (PE08066). Most consumer VOQs indicate that the headlights failed suddenly and without warning leaving the driver with no forward lighting, however some report the headlights flickered or dimmed prior to turning off. In some cases drivers were able to turn the headlights back on after a period of time while others reported the headlights would not come back on at all.
