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.

Swedish car mag says Ford Mondeo is dangerously, illegally overweight [w/video]

Sweden's Teknikens Varld has a reputation for being very persnickety when it comes to auto safety testing, and its latest catch is the Mondeo Titanium Estate 2.0 TDCi 150 bhp S6 MPS (basically a station wagon variant of the Fusion). In addition to the model's mile-long name, it has another problem according to the Swedes, because its weight on the scales does not equal the official numbers for the vehicle. Teknikens Varld claims the wagon is dangerously overweight because it weighs in 4,145 pounds, while Ford officially lists its weight at 3,530 pounds. That 615-pound disparity means that if a family loads it to what they think is the model's gross vehicle weight, it will actually be too heavy, and therefore illegal to drive in Sweden. According to the magazine, when it tried doing this, the rear wheels scraped against the wells, and the estate failed the mag's legendary moose test. However, at 220 pounds over the limit, it passed the test. When reached for comment by Autoblog, Jay Ward, Senior Manager at Ford of Europe Product Communications, explained the reason for the deviation between the official numbers and the magazine's test: "We are aware of this, but this is not an issue that relates specifically to the safety of the Mondeo, but is in fact related to the way in which the cars are tested by the authorities. We provided an Ambiente model for the testing but the car that featured in the magazine test was a Titanium model which has a different weight. We are in discussion with the Swedish Transport Agency to change the framework so the real weight of the Titanium model is reported instead of the Ambiente model which will resolve the issue." Teknikens Varld is well-known for calling out automakers for perceived transgressions. Most recently it leveled criticisms against the all-wheel drive system in the Honda CR-V, and both the Jeep Grand Cherokee and Porsche Macan failed its moose test.

Mondeo weighs 279 kg more than Ford claims. With big load (ie family plus luggage) the car therefore becomes illegal to drive.
