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.

Car-crazy 5-year-old boy writes automakers for treasures, gets big response

Part of the beauty of children is that they can find worth in something adults might deem unworthy or overlook entirely. Five-year-old Patch Hurty didn't see garbage or a broken piece of a car when he spotted a Ford badge lying on the side of a road. He saw an artifact, a souvenir, a start to a collection he could only dream of. Ezra Dyer of Popular Mechanics tells the story of Patch and his quest to turn that one lost badge into a museum of manufacturer logos. According to the article, Hurty is a car fanatic through and through, even using car names as a way of learning to read. After finding the Ford badge near his Connecticut home, he and his mom put together a plan to reach out to dozens of automakers, confessing his love of things on four wheels. In each letter, Patch assembled a picture of himself standing next to one of the cars, and a penny to pay for whatever he hoped was sent his way. The response was unexpectedly and overwhelmingly positive. Of the more than 50 letters he sent out, including to obscure or defunct companies such as Bugatti, Suzuki, and Saturn, a majority responded with warm notes and some type of souvenir. Two of the coolest responses came from Lincoln and Bentley. Lincoln sent a sketch of a Continental (all car lovers enjoy drawing cars, right?), and Bentley sent a wheel center cap. How awesome is that? The story reminds us of something that can easily be lost in all of the negativity involved with the auto industry: Everybody is in this because of a common infatuation with automobiles. For more details on the souvenirs Patch received and accompanying photos, read the rest of the story.

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.
