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 Escort returns... as a concept

Ford is kickin' it old school at the Shanghai Motor Show for 2013 with a new Escort Concept - "a name that stirs up thoughts of basic, affordable transportation rather than great driving dynamics or bold design" as we said in our initial preview of the small C-segment sedan. Or, as Ford puts it, "Customers in China described seeking a vehicle that is stylish - but not one that is arrogant or pretentious." Potato, potahto...
It's an interesting amalgam of design notes with Ford's recent and stylish hexagonal grille up front, flanked by some pretty busy LED light clusters and chrome-trimmed air intakes at the lower extremities of the fascia, but the Escort Concept is not altogether unattractive. Besides its external appearance, we really don't have much information to report - Ford has not yet hinted at what may be powering this little machine, but we'd expect something with four cylinders and less that 2.0 liters of displacement sending a modest number of horses to the front tires.
It probably goes without saying, but we don't expect to see this Escort make its way to the United States, since we already have the Focus and the Fiesta battling it out in the econobox segment. That said, it's very likely to spawn a production model that will roll out here in China and in other developing market where multiple C-segment entries are becoming increasingly common.

Jeep Moab Concepts, Rumors, And More | Autoblog Podcast #470

Episode #470 of the Autoblog Podcast is here. This week, Dan Roth, Chris Bruce, and Brandon Turkus talk about this year's concepts for the Easter Jeep Safari in Moab, rumors of a mid-engined Subaru sports car and the looming reveal of the next Impreza. We also cover more rumors of a simpler Acura NSX, and some other tidbits, including Ford's movie projector patent and the Opel Astra winning the European Car of the Year award. As always, we start with the Autoblog Garage and wrap up by answering your questions. Check out the rundown with times for topics, and thanks for listening!
