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.

2015 Ford Transit Connect Wagon

The last time I tested a Ford Transit Connect, I needed to drive a group of friends to Boyne, MI, for a long weekend of skiing, snowboarding, and shenanigans. At roughly three hours, the trip is just long enough that my friends asked for something comfortable. A Range Rover would've been ideal. Perhaps a Mercedes-Benz GL or Cadillac Escalade. But no, I chose Transit Connect, to put Ford's small van formula to the test. The tiny van was near the end of its lifecycle in 2012, having debuted in Europe in 2003. Its age was reflected in its loud, underpowered, inefficient engine; noisy, harsh ride; and uncomfortable seats. It was so uncomfortable that we had to stop every hour just to stretch our legs. I didn't have such elaborate plans when this 2015 Transit Connect Wagon arrived in my driveway. But after a week behind the wheel, I can tell that road tripping in this van would be a far, far better experience. The most obvious change for the second-generation model is the styling. It's much better looking than the old TC, looking like the high-roofed spawn of a Focus and Escape. There are a few anomalies, though. First, note the word "Wagon" – that implies passenger van, while the cargo/work-minded Transit Connect is called "Van." Next, this Titanium model is only available on the longer-wheelbase, three-row Wagon. With the LWB configuration, the only tailgate option is a single-piece, lift-up hatch. If you want barn-style doors, get cozy with the short-wheelbase, two-row Transit Connect XLT. Regardless of body style, the Transit Connect Wagon's best styling feature is its enormous greenhouse that guarantees excellent visibility from any angle. The interior adopts a dash layout similar to the Focus. The heated leather seats – standard on the Titanium – are nice enough, but better still is that the chairs are actually comfortable now. The plastics on the dash and doors are still hard and scratchy, but fit and finish is solid. And with major contact points and switchgear that have been pilfered from other Ford products, including the steering wheel, the occasional bad bits in the cabin are easy enough to ignore. With room for three folks in the second row and two more in the back, the Transit Connect Wagon fills a role that is more utilitarian and spartan, but not much less versatile than traditional minivans. The middle row seats feature stadium-style raised seating, and both rows can slide forward and back or fold.
