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.

Driving the C8 Corvette, and previewing GM's electric future | Autoblog Podcast #617

In this week's Autoblog Podcast, Editor-in-Chief Greg Migliore is joined by West Coast Editor James Riswick and Road Test Editor Zac Palmer. First they dive right in to the experience of driving the 2020 Chevrolet Corvette, followed by their review of the Mercedes-Benz GLE 350. Then they talk about the week's news, beginning with the whole slew of electric vehicles General Motors surprised us with at its EV Day. Next, they discuss the possibility of Porsche building a hybrid 911, as well as news about Ford's electric Transit van making its way to the U.S.. Last, but not least, they take to the mailbag to help a listener pick his next car in the "Spend My Money" segment.

Ford recalls EcoBoost-powered F-150 and SUVs for brake fluid leak

Ford is recalling approximately 280,000 trucks and SUVs equipped with its 3.5-liter EcoBoost engine to address a potential brake fluid leak. The recall covers the 2016-2017 Ford F-150, 2016-2017 Ford Expedition and the 2016-2017 Lincoln Navigator.  According to Ford's defect report, the issue stems from contamination in the brake fluid causing degradation or damage to the seals in the brake master cylinder, allowing fluid to escape. Ford says that braking performance is not immediately impacted by the leak, and owners may not realize there's a problem until a brake malfunction indicator appears in the cluster, accompanied by a chime.  "If the brake fluid in the reservoir is depleted to a predetermined level, the driver will receive an audible chime, message center alert, and red brake warning indicator in the instrument cluster," Ford said in its defect report to NHTSA. "If the driver continues to operate the vehicle, the drive may begin to experience a change in brake pedal travel and feel, and increased pedal effort." "If a loss of brake fluid is substantial enough to reduce brake function to the front wheels, full braking function would remain in the rear wheel circuit. However, reduced brake function in the front wheels can extend stopping distance, increasing the risk of a crash," Ford said.  The issue can be addressed with a replacement brake master cylinder, which Ford will install free of charge. Ford has already begun notifying dealers and will send notices to customers starting in April.  Recalls Ford Lincoln Ownership Safety Truck SUV
