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.

After Years Of Delays, Rear Visibility Requirements Move Closer To Reality

Regulations that would require automakers to improve rear-view visibility on all new cars and light trucks are nearing completion after six years of delays. The U.S. Department of Transportation sent its proposed rear-visibility rules to the Obama administration for review on Christmas Day. The White House Office of Management and Budget now must finalize the regulations. The rule are intended to minimize the risk of pedestrian deaths from vehicles in reverse, a type of accident that disproportionately affects children. Already in 2014, two children have died from cars backing over them, driven in each case by the children's father. Specifics of the Transportation Department's proposal are not available during the review, but the rules are expected to compel automakers to install rear-view cameras as mandatory equipment on all new vehicles. That's what safety advocates have wanted all along. Thought they were pleased the proposed ruling had finally been issued, there was some worry Friday the final rules would omit the rear-view camera mandate. "We're encouraged, but we're also a little concerned about speculation the rear-view camera may not be in there," said Janette Fennell, the president and founder of Kids and Cars, a nonprofit organization dedicated to protecting children in and around vehicles. "I'm wondering where that might be coming from." On Thursday, The Automotive News had reported the possibility the new standards could offer an alternative to rear-view cameras, such as redesigned mirrors, that improved visibility. The Office of Management and Budget typically completes its reviews of new rules in 90 days, although that can be extended. OMB officials said Friday they do not comment on pending rules. The intent of the rules is to enhance rear visibility for drivers and prevent pedestrian deaths. Approximately 200 pedestrians are backed over in the United States each year, according to estimates from the National Highway Traffic Safety Administration. Accidents Mostly Affect Children Roughly half the victims are children younger than age five. A government analysis concluded approximately half the victims -– 95 to 112 -– could be saved with new regulations. Yet the rules have arrived at a glacial pace. President George W. Bush signed legislation that had been passed with bipartisan Congressional support in 2008. But automakers have fought the idea of adding rear-view cameras, saying it is too expensive.

Vaughn Gittin Jr. takes his dog for a drift

Vaughn Gittin Jr. spends a great deal of his workday going sideways, but he's usually alone in the endeavor. For a guy that is clearly a dog lover, we imagine that can get a bit lonely.
That won't be a problem for Gittin in this latest video, which features the racer hanging out with his good pal Brody (a dog) and everyone's favorite hot hatch, the Ford Fiesta ST.
