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.

Ford reveals all-new Everest SUV at Asia-Pacific forum [w/poll]

While the Explorer may have shifted from a truck-based sport-ute to a car-based crossover, Ford still offers buyers on the other side of the Pacific a Ranger-based SUV in the form of the Everest. And at the Asia-Pacific Economic Cooperation (APEC) Summit in Beijing today, the Blue Oval revealed the all-new version you see here.
Previewed in concept form over a year ago and made specifically for the Asia-Pacific market, the new Ford Everest is designed to be more refined on the road and more capable off of it. Like the Explorer once was, the new Everest is based on a stretched version of the overseas Ford Ranger pickup. Depending on the specific market, Ford will offer the new Everest with a range of engines including a 2.0-liter EcoBoost turbo four and two Duratorq turbodiesels - a 2.2-liter four and a 3.2-liter inline-five - mated to a six-speed automatic transmission.
Earmarked to take on the likes of the Toyota Land Cruiser Prado (known in these parts as the Lexus GX) and the Jeep Grand Cherokee, the new Everest promises rock-crawlers even better off-road capabilities. It's got nearly nine inches of ground clearance, over 30 inches of wading depth, a 29-degree approach and 25-degree departure angles and a set of features including on-the-fly adjustable four-wheel drive.

Inside Ford's high-tech climate chamber

There are two ways an automaker can test its vehicles in extreme climates: it can send said vehicle around the world – from Death Valley to the Arctic Circle – in search of the harshest weather, or it can recreate those conditions in an enclosed environment. We're sure that many automakers undertake some combination of both, but in this latest video clip, Ford shows us around inside it's state-of-the-art climate chamber. At its Driveability Test Facility in Allen Park, MI – inaugurated in 2010 just across the street from the Roush Technology Center – Ford can simulate all sorts of extreme conditions. It can drop the temperature down to -40 degrees Fahrenheit or raise it up to 130, and take it up to a simulated 12,000 feet above sea level or drop it down to 280 feet below. blast it with 150-mile-per-hour winds. It can control the level of humidity, approximate the intensity of the sun and even blast the test vehicle with artificial snow, just like your favorite ski resort. The facility strikes us as an engineering feat as impressive as some of the vehicles it's used to test, but don't take our word for it – scope it out for yourself in this brief two-minute video clip, which even includes some helpful tips for winter driving this holiday season and beyond.
