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.

2019 Los Angeles Auto Show | Autoblog Podcast #605

In this week's Autoblog Podcast, Editor-in-Chief Greg Migliore is joined by Senior Editor, Green, John Beltz Snyder and Associate Editor Zac Palmer. This week, the main topic of discussion is the 2019 Los Angeles Auto Show. Of course, they've gotta talk about the Ford Mustang Mach-E — and its questionable naming scheme. They also run down some other L.A. show highlights including the Toyota RAV4 Prime, Kia Seltos, Lexus LC 500 Convertible and Audi RS Q8. Then they talk about the cars they've been driving: the 2020 Chevy Silverado with the Duramax diesel engine and the 2020 Subaru Legacy Touring XT.

Help make Lego Icon Bronco a reality [UPDATE]

The Lego Ideas process is a pretty neat concept. The website allows anyone to propose a future kit, and if the project gathers 10,000 supporters within a certain amount of time, then the company investigates building it. The creator even gets a cut of the sales. We saw the operation at work last year with a very cool looking Corvette kit that hasn't hit the next stage quite yet. Now, another creator going by the username Legohero1966 has a fantastic looking replica of the Icon 4X4 Bronco hoping for support. The maker nails the boxy, brawny look of the Icon take on the classic Ford Bronco, and the Lego kit even gets the color pretty close. The miniature SUV also features a visible suspension, a removable top and, according to the description, a reel for the winch is hidden in the bumper. Underneath the body, this model even does a pretty good job of replicating the powertrain. As is expected by these kits, the hood, doors and hatch all open; on this one the spare tire carrier even moves out of the way, too. As of this writing, the Icon Bronco kit only has a little over 400 supporters, and that's a long way from the goal. If you like what you see, give the proposal a closer look on Lego Ideas. UPDATE: The original creator of the Icon Bronco kit, Paul Kim, has advised Autoblog that this Lego Ideas proposal was created without his consent, and he has reported the problem there. You can view more pictures of the Bronco and more of Kim's work, here.
