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: 2007 Mercury Mariner Hybrid

Once hybrid vehicles from Honda and Toyota proved to work well in the real world of American streets during the early 2000s, other U.S.-market manufacturers climbed aboard the gasoline-electric bandwagon. Ford introduced the Escape Hybrid for the 2005 model year and sales proved quite strong; its Mercury-badged sibling, the Mariner Hybrid, appeared the following year. The Mariner Hybrid never induced many vehicle shoppers to sign on the line which is dotted, despite gasoline prices going absolutely ape in 2008, though it remained available all the way through the Mercury brand's 2010 demise. Here's one of those rare trucks, found in a Denver-area yard last month. The Escape/Mariner Hybrids got amazing fuel economy for tall, truck-shaped machines, though the serious penny-pinchers with long commutes skipped anything built in the 21st century and began driving up the prices of the once-scorned Geo Metro XFi, gas-sipping champion of the previous decade. The Mercury brand was on the ropes by this time, with not much to distinguish the once-distinctive Mercury machines from their near-identical Ford counterparts. The 1999-2002 Cougar was the last Mercury sold here with no twin brothers over in the Ford showrooms. I do see the occasional Escape Hybrid in places like this, though such gas-saving small SUVs tend to retain their value well enough that it takes a crash to retire one. This Mariner Hybrid hit something hard and either flipped on its side or scraped a guardrail for some distance. The airbags deployed and, presumably, spared the occupants from serious injury. That's the good news. The bad news is that fixing this kind of damage to a 13-year-old vehicle made by a defunct brand just isn't worth it to insurance companies, hybrid-electric powertrain or not. We can assume that the battery pack lives on in another Escape/Mariner. Navigation, Bluetooth, and other features that were considered pretty slick in 2007. This truck was in pretty good shape until the very end. Jill Wagner proved that you can bury a Mercury emblem in volcanic soil and it will grow into a brand-new Mariner Hybrid. That's how science works! You can go to the same field and tap on a Mercury emblem, if you want to get a regular gasoline Mariner.

Junkyard Gem: 1991 Mercury Grand Marquis LS

Ford's now-defunct Mercury Division first began using the Marquis name in 1967, on a sporty full-size hardtop based on the Ford LTD, then began offering the Grand Marquis beginning in the 1979 model year. These big, boxy luxury sedans were replaced by big, curvy luxury sedans (on the same platform) starting with the 1992 model year, so today's Junkyard Gem is one of the very last squared-off Grand Marquises ever built. The 1991 Grand Marquis (or "Grandma Keith," as many refer to it today) looks nearly identical to its 1979 predecessor at a glance, just as the 2011 model doesn't differ much from the 1992 model. Ford saw no reason to follow short-lived fashion trends with its simple, sturdy rear-wheel-drive sedan. Only two Grand Marquis trim levels were available for 1991: the base GS and the (somewhat) upscale LS. The former listed at $18,741 and the latter at $19,241, which comes to about $41,494 and $42,601, respectively, in inflated 2022 dollars). This interior would have seemed comfortingly familiar to a 1968 (or even 1958) Mercury owner time-traveling to 1991.  This is the optional "full grain leather seating surface," which cost an extra $489 (about $1,083 today). Dig those opera lights! Air conditioning was standard equipment in the 1991 Grand Marquis and its wagon counterpart, the Colony Park. The engine is the good old pushrod 5.0-liter Windsor V8, which would be replaced by a far more modern 4.6-liter SOHC mill in the '92 Grand Marquis. This engine was rated at 180 horsepower. A four-speed automatic was the only transmission available. The early 1990s ended up being the last gasp for padded vinyl roofs being considered mainstream equipment on new Detroit cars; this one was called the "Formal Coach" roof and cost an additional 725 bucks ($1,605 now). Such roofs were still available on a few cars later in the decade, but their time had passed. Why would such a clean Grandma Keith end up in a place like this? That's easy: it got T-boned directly into the right front wheel, mangling the body and bending up the suspension. This damage might have been worth fixing when the car was five years old, but it's a write-off when it happens to a 31-year-old Ford Panther. 1991 Mercury Grand Marquis Commercial - Savings Ad The granddaddy of them all, and on sale in South Texas!
