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.

Ford F-150 Raptor, Nissan Pathfinder and Frontier, and Cadillac Blackwings | Autoblog Podcast #663

In this week's Autoblog Podcast, Editor-in-Chief Greg Migliore is joined by News Editor Joel Stocksdale and Associate Editor Byron Hurd. It's a packed show this week, and the three dive straight into the week's truck loads of news, starting with the unveiling of the Cadillac CT4-V and CT5-V Blackwing variants, followed by the 2021 Ford F-150 Raptor and the 2022 Nissan Pathfinder and Frontier. Next, they move on to what they've been driving. For Byron, that means more trucks. Lots and lots of trucks. Joel recently spent some time behind the wheel of a Bronco Sport, and the three discuss its merits as both an off- and on-road crossover. From this, they segue into a "Spend My Money" featuring Senior Producer Chris McGraw's neighbor, who acquired an older Forest Service Bronco and wants tips on what to do with it.  Autoblog Podcast #663 Get The Podcast iTunes – Subscribe to the Autoblog Podcast in iTunes RSS – Add the Autoblog Podcast feed to your RSS aggregator MP3 – Download the MP3 directly Rundown News 2022 Cadillac CT5-V Blackwing, CT4-V Blackwing bring big performance back to the brand 2021 Ford F-150 Raptor revealed, packing EcoBoost power, coil suspension and factory 37s 2022 Nissan Frontier enters the modern midsize truck world with big redesign 2022 Nissan Pathfinder debuts with fresh new duds, no more CVT What we're driving: 2021 Ford F-150 2021 Nissan Titan Pro-4X 2021 Toyota Tundra TRD Pro 2021 Ford Bronco Sport Spend My Money Feedback Email – Podcast@Autoblog.com Review the show on iTunes Autoblog is now live on your smart speakers and voice assistants with the audio Autoblog Daily Digest.
