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.

Watch these videos of an NHRA racer's bodywork blowing off into a crowd

Just a few months ago, fan safety at racetracks was a hot topic following the last-lap NASCAR Nationwide Series crash at Daytona that sent large pieces of racecars into the grandstands injuring 33 fans. Now, a freak incident at a National Hot Rod Association event resulted in a drag racer's bodywork flying into the crowd at the NHRA Four-Wide Nationals in Charlotte over the weekend. The carbon-fiber body of Robert Hight's Ford Mustang funny car blew off toward the end of a run when his engine exploded, but fortunately, the two fans evaluated after the incident were later released without serious injury.
As you can see in the image above, the body flew high into the air before landing on a walkway in front of the grandstands, a bit of happenstance that likely gave most fans enough time and space to move out of the way. Scroll down to watch a couple of videos showing what happened, including one from a fan's perspective that also reveals what appears to be part of the body's metal bracing landing dangerously close to the crowd.

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.
