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.

Blue Oval's new Cargo cab-over rig is largest "One Ford" initiative yet

The imposing commercial truck above has a feature that might be surprising to most Autoblog readers - a Blue Oval emblem on the front. Here in North America, Ford simply doesn't play in the eighteen-wheeler sandbox, but that doesn't mean that the Dearborn-based automaker is absent in the heavy hauling space in other parts of the globe. In fact, Ford presently fields two completely different big rig ranges under the Cargo moniker - one a product of an Eastern Europe/Turkey joint venture, and another from Brazil. But that's about to start changing with the advent of this new cab-over model seen here.
Unveiled in São Paulo, Brazil, this new generation of Cargo is perhaps the largest physical embodiment of CEO Alan Mulally's "One Ford" global streamlining strategy. Instead of multiple models, company engineers have developed a new single truck that it says will better meet the needs of truckers in all markets. Designed to compete in what's known as the "extra heavy-duty segment" elsewhere in the world, this Cargo was developed jointly by Ford engineering teams in Brazil, Turkey and Europe.
Specifics remain hard to come by (read: unreleased), but Ford is promising an all-new engine enabling hauling capability of up to 56 tons while still returning excellent fuel economy. Ford's global Cargo lineup will henceforth consist of a dozen models, but Ford tells Autoblog has no plans to bring this hot and heavy-duty action to North America.

Watch NASCAR racer Brad Keselowski do a burnout... in a hotel conference room

A vast majority of hotels frown upon smoking inside the building these days, but Brad Keselowski doesn't follow the rules. During his introduction at the 2013 MiilerCoors Distribution Convention, the reigning NASCAR Sprint Cup champion smoked the tires of his Miller-sponsored Ford Fusion stock car, adding a pair of thick, black stripes to the carpeting of the Marriott World Center's conference room.
This definitely isn't a high-quality video, but it's the perfect vantage point to watch Keselowski lay down some rubber and receive a well-deserved standing ovation after pulling up in front of the crowd. Check out the short-but-sweet video posted below.
