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.

Petrolicious shows Mercedes 280SL as architecture in motion

While still an absolute beauty today, the design of the pagoda-roof W113 Mercedes-Benz SL was revolutionary when it debuted. Moving away from the soft curves of the previous SL models, the all-new generation brought an upright, angular shape that was as much architectural as automotive. In the latest video from Petrolicious, owner and architect Daniel Monti expounds on the inspiration that he gets from his 1969 280SL's fantastic styling. The roof is the most famous design feature of this generation of SL. Look at the top from the front or back, and you can see a gentle, downward arc that evokes the look of a pagoda. That one styling element is also a fabulous counterpoint to a vehicle that is largely more angular than curvaceous. Petrolicious wonderfully illustrates how some of the SL's form-follows-function design aesthetic can be found in the architect's work in this video's heaping helping of mid-century modern goodness.

Ford announces two recalls, 442k vehicles affected in North America

Ford is announcing two recalls for North American that affect a total of 442,300 vehicles and multiple model lines. The larger campaign covers the possibility of electric power steering systems that can fail in the 2011-2013 Ford Flex, Taurus, Lincoln MKS, and MKT; the 2011-2012 Ford Fusion and Lincoln MKZ; and the 2011 Mercury Milan. This recall affects 422,814 vehicles in North America, including 393,622 in the United States, 25,195 in Canada, and 3,997 in Mexico. According to the company, an intermittent electrical connection can cause the power steering to cut out, although manual steering would still work. Ford knows of four minor accidents from this issue, but there are no injuries. Depending on trouble codes from the vehicle, dealers will either upgrade software for the power steering control module or replace the steering gear. The second recall covers 19,486 examples of the 2015 Ford Mustang with the 2.3-liter EcoBoost turbocharged four-cylinder engine with a production date between February 14, 2014, and February 10, 2015 at the Flat Rock Assembly Plant. Specifically, there are 19,095 of these in the US and 391 in Canada. These pony cars can show elevated underbody temperatures, which can lead to degradation of the fuel tank, fuel vapor lines, and parking brake cable seals. There are no reports of accidents, injuries or fires from this, though. To fix things, dealers will install a better-insulated fuel tank shield, add thermal patches around the tank and parking brake cable, and put thermal wraps around the fuel vapor lines. You can read the specific build dates and locations for the models affected by the power steering issue in Ford's press release below the video.
