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.

Ford to revisit CVTs?

Today, Ford wishes its first experience with non-hybrid continuously variable transmissions was far behind it. The Blue Oval was awash in complaints and a couple of class-action lawsuits over the CVTs used in its 2005-2007 Ford Freestyle, Five Hundred and Mercury Montego models, which were a manufactured in Batavia, Ohio as part of a joint venture with ZF. The company gave up on the CVT after just two years, but with fuel economy standards pressing automakers to conjure new tricks, Ford's global product development head, Raj Nair, is now saying the transmissions might make a return, "particularly in the low torque applications," says Automotive News. An obvious candidate for CVT consideration is the 1.0-liter Fiesta that can presently only be had with a five-speed manual. Beyond that, the company's 1.6-liter and 2.0-liter four-cylinder engines might fit the bill. Ford hasn't given any indication as to what vehicles it might use to reintroduce the CVT to the US market, or hints about timeline or who would develop it, however. Some CVT trivia: The 1990 Subaru Justy II was the first US passenger car offered with a continuously variable transmission - Subaru called it the ECVT. It handled gearing duties for a 1.2-liter, inline three-cylinder engine that got all of 70 horsepower. A contemporary blurb about the car begins with "Goodness, gracious, great gobs of gimmickry," and goes on to say that "We can't imagine where you would take this car for repairs, but we are certain that the one mechanic in the world who can fix it lives in a very expensive house." The transmission didn't win any fans, but the ECVT and the car have been largely forgotten, while Subaru played the long game and now you'll find its vastly improved Lineartronic CVT on six of the eight models it sells.

Ford dominates most-stolen SUV list

The Ford Escape leads the NICB's list with 1,421 examples stolen.
If you drive a recent Ford SUV or crossover, you may want to keep a watchful eye out for thieves - especially if you live in the New York metro area or in Detroit. A new study from the National Insurance Crime Bureau has named three Ford models as the most likely vehicles in their genre to be stolen, with CUVs in general being especially attractive to bandits.
