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.

Toyota tops Consumer Reports best, worst used car values

We often mock Toyota for building boring, soulless cars, but a new study by Consumer Reports suggests that regardless of whether that's true, the company has some of the best used cars on the market. In its report on used cars from 2004-2013, the Japanese automaker had 11 vehicles among its brands on the list - more than any other automaker.
CR breaks the list down by cost and vehicle size, and Toyota has at least one entry at every price point and in nearly every segment. To score a recommendation, a vehicle had to perform well in the magazine's initial tests and score above-average reliability results. It also tried to only suggest cars with electronic stability control. Of the 28 recommended vehicles, Honda/Acura had the second most mentions at six, and Ford, Hyundai and Subaru managed two each.
The Detroit brands also made it to the list, but not in a positive way. Consumer Reports compiled a list of 22 vehicles it wouldn't recommend because "they have multiple years of much-worse-than-average overall reliability." General Motors had the most unrecommended models on the list at six, but Chrysler and Ford weren't far behind, with five cars each from their brands not making the grade. The full list of recommendations is available on CR's website.
