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.

Wrap up some fun with Ford's commercial vehicle configurator

Ford has combined multiple steps into one with its commercial vehicle configurator, which allows users to choose, design and place orders for the Transit, Transit Connect, E-Series vans and F-Series Super Duty trucks.
The most interesting part of the new configurator is a fairly robust design tool. Users are able to choose paint color and wrap the vehicle, and then create their own graphics. No materials are needed - Ford provides numerous background textures, text boxes, plenty of shapes and 20 categories of images including floral, construction, plumbing and skylines. Self-created designs or images can be uploaded to the system as well.
We played around with the design tool a bit and uploaded our own image to create the Autoblog Podcast Live van you see here. Feel free to check out the configurator and make your own design.

Ford spotted testing new Focus RS at the Nurburgring

Ford is expected to be launching a revised version of the Focus ST soon, but the latest snapshots from our spy photographers at the Nürburgring suggest that the Blue Oval is already working on an even more potent example: the new Focus RS.
Though the partially disguised test mule is wearing an ST badge (along with a Dewey sticker that makes us wonder what adventures Huey and Louie are up to and what manner of duck-tail rear spoiler they may be wearing), there are several tell-tale signs that something else is afoot here. There's a larger front air dam, bigger brake calipers, dual exhaust tips (instead of the central exhaust on the ST) and a reshaped wing protruding from the trailing edge of the roof.
That may all be well and fine, but what's under the hood? We don't know yet for sure, but word has it that Ford is preparing to port over the 2.3-liter turbo four offered in the new Mustang, where it packs 305 horsepower and almost as much torque - potentially retuned to produce even more for the top-of-the-line Focus, which could channel it all to the front wheels like the last model or pack an all-wheel drive system. The Global C platform on which the Focus is based does, after all, also underpin AWD models like the Ford Escape and Lincoln MKC.
