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.

Gladiators, Pilots, and Palisades, plus a couple boring crossovers | Autoblog Podcast #562

On this week's Autoblog Podcast, Editor-in-Chief Greg Migliore is joined by Consumer Editor Jeremy Korzeniewski. The duo discuss the leaked Jeep Gladiator, Ford's Baby Bronco, the Aston Martin DBX, and then touch on other reborn names like the Honda Pilot. They also discuss how boring crossovers have taken over as the family car of choice in the United States and debate the merits of turbocharged V6 engines versus the classic American V8.

Ford unveils all-new 2016 F-650 and F-750 at NTEA

Medium-duty work trucks might not be the most exciting vehicles, but they perform necessary jobs everyday. Ford is in the process of a complete refresh of its entire commercial vehicle lineup over the next 18 months, and it is debuting the all-new versions of its F-650 and F-750 trucks at the NTEA Work Truck Show in Indianapolis, IN.
"The all-new F-650/F-750 allow us to leverage our strengths and sales leadership in Classes 1 to 5 to create a better F-650/F-750 that's designed, engineered and built by Ford in the USA," said Ford spokesperson Mike Levine to Autoblog via email.
Huge amounts of torque is vital for trucks like these, and both models are offered with some of Fords biggest engines. Buyers can opt for either the 6.7-liter Power Stroke V8 diesel with TorqShift 6-speed automatic with available power takeoff or a gasoline-fueled 6.8-liter V10 with a 6-speed automatic. The V10 can also be ordered from the factory to be fueled by compressed natural gas or liquid propane gas.
