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.

Detroit 3 to implement delayed unified towing standards for 2015

Car buyers have a responsibility to be well-informed consumers. That's not always a very simple task, but some guidelines are self-evident. If you live in a very snowy climate, you generally know a Ford Mustang or Chevrolet Camaro might not be as viable a vehicle choice as an all-wheel drive Explorer or Traverse, for example. If you want a fuel-efficient car, it's generally a good idea to know the difference between a diesel and a hybrid. But what if it's kind of tough to be an informed consumer? What if the information you need is more difficult to come by, or worse, based on different standards for each vehicle? Well, in that case, you might be a truck shopper. For years, customers of light-duty pickups have had to suffer through different ratings of towing capacities for each brand. For 2015 model year trucks, though, that will no longer be a problem. According to Automotive News, General Motors, Ford and Chrysler Group have announced that starting with next year's models, a common standard will be used to measure towing capacity. The Detroit Three will join Toyota, which adopted the Society of Automotive Engineers' so-called SAE J2807 standards way back in 2011. The standard was originally supposed to be in place for MY2013, but concerns that it would lower the overall stated capacity for trucks led Detroit automakers to pass. Ford originally passed, claiming it'd wait until its new F-150 was launched to adopt the new standards, leading GM and Ram to follow suit. Nissan, meanwhile, has said it will adopt the new standards as its vehicles are updated, meaning the company's next-generation Titan should adhere to the same tow ratings as its competitors. While the adoption of SAE J2807 will be helpful for light-duty customers, those interested in bigger trucks will still be left with differing standards. There is no sign of the new tow standards being adopted for the heavy-duty market.

China's auto sales continue to drop

The days of unending growth of carmakers in China look to be over, and some analysts are even forecasting a net drop in volume this year, The Detroit News reports. After falling numbers in June and July, the China Association of Automobile Manufacturers tallied total sales, including trucks and buses, in August to 1.7 million, down 3 percent from 2014. There were some tiny specs of good news in China, but there's no turnaround in sight. Total vehicle sales from January to August are actually still up but only 2.6 percent. Like the rest of the world, SUVs are booming with numbers up 45.6 percent from the previous year. Honda managed a very impressive 50.7 percent gain on the strength of the CR-V and Vezel (the HR-V here), according to The Detroit News. Also, the country's domestic automakers, which generally offer less expensive products, posted a 2.5 percent growth in sales. The news continues to look bad for Detroit's automakers, though. Volume from General Motors dropped 4.8 percent in August, and Ford fell 3 percent in August. Both of them have invested significant amounts there in the past years. The vehicle industry in China grew last year, but there was burgeoning evidence of weakness. At the end of 2014, dealers there pushed back against huge inventories pushed by automakers. Even before the big drops began in June, GM saw the writing on the wall and started cutting prices. BMW responded to the slump by cutting back production to deal with the changing demand.
