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.

Man chases down truck thief and steams it all on Facebook

A Washington man chased down a truck stolen from his family's dealership last Saturday and livestreamed the event on Facebook. According to KOMO, a 2005 Ford F-250 was stolen from Sunrise Auto Sales in Eatonville, Washington on the morning of October 8. Aaron Babcock, who co-owns the small dealership with his father David, told reporters that after reviewing surveillance footage, he later spotted the truck while riding his motorcycle on Webster Road East. "I watched my cameras and found the video of a man lurking around and ending up taking off with my truck," Babcock told KOMO. "Cops came and made a case. Three hours later I was on my motorcycle in Graham, and they drove by me oncoming. It still had dealer stickers on it. It said diesel on the window and it had our dealer plate on it. It stuck out like a sore thumb. It was really easy to see." Once he spotted the stolen Super Duty, he wheeled his bike around and gave chase. He attempted to call 911, but was unsure if the dispatcher heard him due to noise from the wind and the bike's engine. So he fired up Facebook live and started streaming his chase, giving running commentary and updating his location as he chased the slow-moving truck. "I wasn't going to let him get away. I was going to try follow him down. I had no idea what to do," Babcock said. "Nobody could hear me on the phone so I just figured the first thing to do is pull up Facebook live." Babcock's Facebook friends pitched in by calling 911 to report the chase and even jumping in their own cars to follow the truck. At one point, he pulled alongside the truck and recognized both men in the cab. The driver was the man seen lurking around the dealer lot in the surveillance video, and the passenger was an old friend of Babcock's. "I know who you are!" he shouted at them, but the hunkered down and kept driving. Eventually, Babcock lost cell phone signal and the livestream ended. Eatonville police, who by this point were well aware of the incident, caught up with the truck in the 8400 block of 356th Street South in Eatonville. The driver was arrested and the passenger was questioned and released. Both denied stealing the vehicle or knowing it was stolen. Two sets of keys from Sunrise Auto Sales and a stolen credit card were also recovered from the truck. Related Video

How Ford plans to handle insurance and repair questions surrounding new aluminum-bodied F-150

Building a car out of aluminum has a number of benefits - the lighter weight allows the vehicle to be more agile, more fuel efficient, make better use of its power and be more resistant to dings and dents. The downside to the advanced construction, though, is that repairs are both challenging and expensive. That's troubling for the new, aluminum-bodied Ford F-150, because it's kind of made a name for itself as a rugged, durable work vehicle.
How will the legions of Ford buyers cope when it comes time to insure and repair their new trucks? Well, according to Ford, it's expecting a ten-percent jump in insurance costs for the aluminum-bodied F-150, although Ford's truck marketing manager, Doug Scott, was quick to point out that the F-150 is generally cheaper to insure than its competition from Ram and General Motors. "At the end of the day, that's sort of a wash," Scott told Automotive News at last week's Detroit Auto Show. "We've spent a lot of time and feel very comfortable that that's not going to be an inhibitor."
The other issue facing Ford is the distinct lack of body shops that have the training or equipment to repair aluminum-bodied vehicles. AN cites an estimate from the Automotive Service Association claiming that of the 30,000 independent body shops in the US, less than 10 percent are able to work on aluminum.
