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.

Fields 'required' to use private aircraft, could make $5.25M as Ford CEO this year

Mark Fields' travels on the friendly skies will soon be a relatively personal affair, as the new CEO at Ford will be required to resume air travel via the company's private planes. Fields caught plenty of flak in 2007 for flying on the company's dime to visit his family in Florida. He's since flown commercial.
According to Ford spokesperson Susan Krusel, who spoke to Bloomberg, Fields (pictured above right, with Bill Ford, Jr. at center and Alan Mulally at left) will switch to private travel "for safety and to maximize his availability for company business." In addition to his new travel arrangements, the 53-year-old exec's salary and bonuses have been revealed.
Regulatory filings by Ford revealed that Fields, whose first day in the big chair was July 1, will receive a base salary this year of $1.25 million and he'll be eligible for $3.5 million in bonuses, both of which are lower than Alan Mulally's $2 million salary and $5.88 million in bonuses received last year. That's also lower than General Motors CEO Mary Barra's alleged $1.6-million salary and considerably less than Sergio Marchionne's $3.19-million fixed salary from Fiat. Despite falling short of other CEOs, Fields' new pay still represents a 33-percent increase over his pay as Chief Operating Officer.
