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.

Recharge Wrap-up: Ford HQ gets giant solar array, Chevy City Express gets 24 MPG city

Ford will be building Michigan's largest solar array at its Dearborn headquarters. With funding from DTE Energy, the solar carport will provide covered parking, as well 30 charging stations for electric vehicles. The array is expected to generate 1.13 million kWh per year for Ford's operations, and offset 794 metric tons of carbon emissions. Read more in the press release below. Chevrolet announced the fuel economy for the 2015 City Express, at 25 mpg combined. The cargo van is rated at 24 mpg in the city, and 26 mpg on the highway. Chevy credits the van's inline four-cylinder engine and continuously variable transmission for its impressive city mileage. For its customers - which are mainly businesses - "The fuel economy of the City Express will help stretch their dollar at the pump and give them the flexibility to invest the savings back into their business," says Chevrolet's Ed Peper. The City Express starts at $22,950. Read more in the press release below. Engineers at the University of Wisconsin have developed an efficient engine that runs on a diesel-gas blend. The engine, which uses a computer to control the blend proportions, is about 15 percent more efficient than the any diesel engine according to mechanical engineering professor Rolf Reitz. The team has put the experimental reactivity controlled compression ignition (RCCI) engine in a demonstration car - a 2009 Saturn. "This vehicle can do 50 miles per gallon," says Reitz, who believes the system could be improved further. Read more at Wisconsin Public Radio. The Southeast Alternative Fuel Conference and Expo will take place in October in Raleigh, North Carolina. Held at the NC Clean Energy Technology Center from October 22-24, the event will feature a variety of exhibitors, speakers and, most importantly, alternatively powered vehicles. "The three day conference will be a one-stop shop for fleet and transportation related decision makers to learn about return on investment, efficiency and alternative transportation fuels such as biodiesel, electricity, ethanol, propane and natural gas," says Anne Tazewell of the NC Clean Energy Technology Center. If you can't make it to Raleigh for the Expo, you can still enter to win a free two-year lease of a Nissan Leaf at the Center's website. Learn more about the event in the press release, below.

From CrabWalks at dawn to post-testing sushi: An inside look at Autoblog’s Tech of the Year Award

TROY, Mich. — On a chilly fall morning, Senior Editor John Snyder rolled into a sleepy suburban park tucked away next to a cemetery a few miles north of Detroit. Driving diagonally — CrabWalking — in the GMC Hummer EV, he made quite the entrance as he maneuvered across the parking lot to the bemusement of Autoblog editors and a few curious park-goers up for their early morning runs.  Snyder got everyoneÂ’s attention, and as we evaluate the latest wave of technologies transforming the automotive industry, pizazz matters. We added "wow factor" to our criteria for the 2022 Autoblog Technology of the Year Award, in keeping with the times. The HummerÂ’s CrabWalk feature might have won, had wowness been the only criteria, but we also scored the technologies on significance and how well they work.  As it was, the Hummer finished a competitive second this year, behind FordÂ’s Onboard Scales and Smart Hitch, which make towing and hauling easier for modern truck owners. The Genesis GV60Â’s Biometrics was within striking distance in third place, bringing the facial recognition and fingerprint tech commonly used in phones to your car. For more on FordÂ’s win — its second straight Autoblog Technology of the Year Award — read Road Test Editor Zac PalmerÂ’s complete recap. Many have asked: Why do Tech of the Year? For Autoblog, itÂ’s been a point of pride for nearly a decade. In the early days it was a way to differentiate ourselves from print magazines, some of which have been giving out car of the year awards since the early days of the Cold War. With Tech of the Year, we seek to highlight the ways experiencing a vehicle is changing. It was true in 2013 and resonates even more as we head into 2023. Cars and transportation have changed more in the past decade than in arguably the previous four. At its most basic experience, driving a 1985 Buick LeSabre with a decent radio and comfy interior was not all that different from driving a 2005 Buick Lacrosse. Just a few years later, many cars had touchscreens, the internet and some means of driver assistance. Ford joins Tesla as the only two-time winner of Tech of the Year. The Blue Oval captured the award last year for its Pro Power Onboard generator. Tesla won in 2014 for its Supercharger network, and the Model S won in 2016, when we briefly gave out a “technology car” of the year award, in addition to honoring a particular feature.
