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.

Truck Week, Jeep Grand Commander, and RIP Ford sedans | Autoblog Podcast #538

On this week's Autoblog Podcast, Editor-in-Chief Greg Migliore is joined by Green Editor John Beltz Snyder and Associate Editor Joel Stocksdale. We talk about driving the 2018 Ford F-150 and 2019 Ram 1500 Tradesman we have at the office this week. We discuss Ford discontinuing most of its cars, salute the Jeep Grand Commander, and reminisce about our favorite car toys. As usual, we'll also spend a listener's money on a car.

Biden will travel to Michigan Tuesday to speak about UAW strike

President Joe Biden will travel to Michigan on Tuesday to speak about the United Auto Workers' strike against Detroit automakers, the president announced Friday on X, the social media platform formerly known as Twitter. The UAW earlier invited Biden to join workers on the picket line in their fight for higher wages. The strike is entering its second week, with the UAW reporting progress in its talks with Ford, yet widening its walkout against GM and Stellantis.  Fain called all GM and Stellantis parts distribution facilities to strike on Friday, announcing walkouts at 38 locations across 20 states. All of the plants already on strike will remain on strike, according to Fain. Former President Donald Trump is also expected to visit the picket lines next week in Michigan, likely the day after Biden's visit. The UAW last week launched unprecedented, simultaneous strikes at one assembly plant each of General Motors, Ford and Chrysler parent Stellantis, but analysts expect any wider strike will include plants that build highly profitable pickup trucks, GM's Chevy Silverado and Stellantis' Ram. About 12,700 workers walked out at plants in Missouri, Michigan and Ohio, which produce the Ford Bronco, Jeep Wrangler and Chevrolet Colorado, alongside other popular models.
