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.

10 automakers shack up in Detroit hotel to talk Takata airbags

Since Takata has decided not to take the lead concerning potential issues with its airbag inflators, the automakers have. Perhaps that's unsurprising, since it's the automakers, not Takata, that will take a beating on the dealership floor if consumers decide its models are a health hazards. The Detroit News reports that Toyota, Honda, General Motors, Ford, Chrysler, Mazda, BMW, Nissan, Mitsubishi and Subaru met in a hotel conference room near the Detroit Metropolitan Airport last week to sort out a way to understand the technical issues involved. So far, faulty airbag inflators have been ruled the cause of five deaths and 50 injuries around the world, but neither Takata nor investigators understands exactly why the inflators are malfunctioning. The National Highway Traffic Safety Administration recently asked Takata to issue a national recall, Takata declined, citing a minuscule failure rate and the fact that it's still investigating the issue. Toyota and Honda then made an industry-wide appeal for "a coordinated, comprehensive testing program" that would pinpoint the problem inflators and get them replaced, and that's what the Detroit meeting was about. Numerous issues, however, will make this a long row to hoe: simply getting the parts to replace the nearly 20 million inflators in cars recalled around the world so far - even working with other suppliers - will take a years, but more importantly, no one knows if the replacement inflators currently being installed will suffer the same issue. Answers will hopefully come quickly with Takata, the ten automakers and NHTSA all independently investigating the problem.

1947 Chevy rat rod pickup leaves rubber and smoke in its wake

Cool comes in multiple flavors. One one hand, we have the sophisticated attraction of svelte design and the efficient use of power. Of course, on the other hand there is the allure of being the bad boy and going against the grain. That is part of the appeal of rat rods. Ideally, they are built without rules to an owner's specific tastes, and this widened and heavily modified 1947 Chevrolet pickup rod is a perfect example of that spirit.
Coming down the highway with a bent grille, rusted body and pouring smoke, it looks like the pickup from hell. It backs up the looks with some very impressive mechanicals too. Owner Troy Gubser says that the truck packs a Ford Power Stroke diesel with to 42 pounds of boost that runs out of 8-inch exhaust stacks at the back. He claims it managed 505 horsepower and 885 pound-feet of torque on the dyno. To harness all that power, this hot rod has a ZF five-speed manual gearbox with a ceramic clutch and short-throw shifter. Plus, it has cool little features like a doorbell on the tailgate that operates an air horn.
You might not expect a truck like this to actually be useful, but it has a fifth wheel coupling to haul an RV around drag races and car shows. The air suspension also probably keeps the ride fairly comfy when Gubser wants it to be. Scroll down to check out this beastly rat rod pickup and watch it engage in some diesel drag racing. Warning, there is some NSFW language.
