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: 1955 Mercury Montclair Coupe

I find plenty of 1950s Detroit vehicles in the big self-service car graveyards I frequent, but most of them are fairly ordinary sedans that never stood much chance of getting fixed up and put back on the road. Such is not the case with today's Junkyard Gem, which is a top-trim-level, heavily optioned hardtop coupe from one of the most desirable model years of the tailfins-and-chrome postwar era. Nearly every Mercury model ever made was a Ford model with some cosmetic changes applied, and the '55s looked very similar to their mechanically identical Ford brethren. In 1955, the new Mercury came in three trim levels: the entry-level Custom, the medium-zoot Monterey, and the glitzy Montclair. Each was available as a hardtop coupe and four-door sedan, with wagon versions of the Custom and Monterey. The Montclair could be purchased as a convertible or with the wild "Sun Valley" glass roof. The Montclair got its own line of hallucinogenic two-tone interiors, in order to make the daily lives of Europeans feel even more gray and penurious (the UK only dropped food rationing in 1954, and the two Germanies were still clearing the rubble of their blown-up cities). This car's upholstery has been bleached by decades of sitting outside in the harsh High Plains climate, but it started out as vivid red and white "Chromatex" fabric. The list price on this car was $2,631, or about $29,200 in 2022 dollars. The Sun Valley and convertible Montclair each cost $2,712 ($30,100 today). Ford didn't offer a corresponding hardtop coupe in 1955, though the Fairlane Crown Victoria two-door did look extremely snazzy (and cost a mere $2,302— $25,545 now— with the same V8 engine as the Monterey). Meanwhile, Oldsmobile offered the handsome 88 Super Holiday Coupe for $2,714, though the Montclair had the more powerful engine. Oldsmobile had been selling new cars with overhead-valve V8s since the 1949 model year, while Ford didn't ditch the Model A-era flathead V8 for new U.S.-market cars until the 1954 model year (you could buy a new Simca Esplanada in Brazil with an Ardun-headed Ford V8-60 all the way until 1969). GM's Chevrolet Division got all the press in 1955 with the introduction of the brand-new small-block V8 engine, but Ford's 292-cubic-inch (4.8-liter) Y-Block V8 made more power than the 265-cube (4.3-liter) Chevy and the 324ci Olds Rocket 88.

Ford recalling 370,000 Crown Vic, Grand Marquis and Town Car models

The Detroit News is reporting that Ford will recall some 370,000 Crown Victoria (pictured), Mercury Grand Marquis and Lincoln Town Car vehicles from model years 2005 through 2011, for an issue regarding the lower intermediate steering shaft. 355,000 of the vehicles in question were sold in the US, with the other 15,000 sold in Canada.
The report indicates that corrosion of the lower intermediate steering shaft could cause a "loss of steering," presumably because of a partial or complete failure of the part. The report points out the dealers will inspect and replace the offending steering component for recalled cars, and may also secure a lower steering column bearing and replace the upper intermediate steering shaft as needed. The company is unaware of any reports of the faulty part causing any accidents or injuries.
Ford helpfully lists states in which corrosion is more likely to have taken place, mostly in the Snow Belt, as you might guess. Connecticut, Delaware, Illinois, Indiana, Iowa, Kentucky, Maine, Maryland, Massachusetts, Michigan, Minnesota, Missouri, New Hampshire, New Jersey, New York, Ohio, Pennsylvania, Rhode Island, Vermont, Virginia, Wisconsin, West Virginia, and the District of Columbia are listed.
