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.

Check out Ford's fully automated self-parking car [w/video]

As automakers continue to find uses for autonomous and semi-autonomous vehicle technology, Ford of Europe has announced that it is developing a self-parking system for future use. More advanced than the Active Park Assist already offered in many Ford products, the new Fully Assisted Parking Aid can take full control of the vehicle and can navigate angled and perpendicular parking spots.
While today's Active Park Assist can only parallel park with the driver controlling the gas, brake and gear selection, Fully Assisted Parking Aid can operate steering, gas, brake and gear selection all while making sure the car is properly parked in the intended space. As with APA, the driver pushes a button to make the car look for a proper spot (at speeds of up to 18 miles per hour), and when an adequate space is located, the operator pushes another button (either inside the car or outside via remote control) for the car to park itself - the button must be pressed throughout the whole parking maneuver. Even though Ford says that the car can effect gear selections on its own, the system must still start from Neutral, and the automaker isn't saying whether the car can put itself into Park when done or put itself in Drive when the operator is ready to go.
Ford is also taking the opportunity to announce its new Obstacle Avoidance technology. This automated system is able to detect objects - including pedestrians - in the road, warn drivers of said objects and, if needed, stop and steer automatically to avoid hitting the obstacle. Both systems are still in the prototype phase, so there is no word as to when we could see either on a production vehicle.

Did a US automaker blow the whistle on Hyundai, Kia fuel economy issue?

In all of the most hotly contested mainstream segments of the motoring universe, the difference of one mile per gallon averaged on a widow sticker can mean the difference between a sale and a walk-off - to say nothing of two or three mpg. So, when Hyundai and Kia were forced to reveal that many of their 40-mpg ratings were actually 38s and 37s, well, it made for big news.
It also, conceivably, made for a competitive disadvantage immediately, when the Korean automakers' products were being shopped versus the guys down the block. And it's that disadvantage that makes a recent story from Automotive News so juicy.
AN is reporting that Margo Oge, former head of the Environmental Protection Agency's Office of Transportation and Air Quality, got a tip in 2010 that Hyundai/Kia were "cheating" to get its impressive fuel economy numbers. The tip, said Oge (who retired from the EPA this past September), came from a senior vice president from a domestic automaker. The source was credible enough for Oge to launch an audit of the Hyundai figures, which ultimately lead to the debacle that we reported on a few months ago, and that the Korean company has been trying to bounce back from ever since.
