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 Mustang GT Bi-Fuel CNG

Highly intrigued, we recently visited a Southern California Gas Company office to check out several hybrid vehicles promising something new. Unlike more commonplace gasoline-electric hybrids, we were there to evaluate innovative gasoline-compressed natural gas (CNG) hybrids - yes, they run on unleaded gasoline and compressed natural gas. According to the experts on hand, this arrangement delivers extended range and reduced emissions while chipping in with lower operating costs than pure-gasoline vehicles. There are advantages over its gasoline-electric counterparts, as well.
The program is part of a three-way collaboration between The Carlab, a Southern California-based automotive consulting firm, Landi Renzo USA, a company specializing in alternative fuel solutions, and America's Natural Gas Alliance, a group that promotes CNG. Long story short, the team has engineered a way to allow a modified internal combustion vehicle to seamlessly switch between two fuels (gasoline and CNG) with no driver intervention. In theory, and if it works as well as promised, it's a win-win for the vehicle owner and the environment.
Parked at the Gas Company office were six different gasoline-CNG hybrid vehicles. To demonstrate the technology's versatility (just about any gasoline vehicle may be modified) Carlab brought a varied assortment of bodystyles, each from a different automaker. After taking a quick glance at the half-dozen in the parking lot, we made a beeline for the performance-oriented Ford Mustang GT - a 2012 model - with the six-speed manual gearbox.

Child cobalt miners: Automakers pledge ethical minerals sourcing for EVs

BERLIN - Leading carmakers including Volkswagen and Toyota pledged on Wednesday to uphold ethical and socially responsible standards in their purchases of minerals for an expected boom in electric vehicle production. Demand for minerals such as cobalt, graphite and lithium is forecast to soar in the coming years as governments crack down on vehicle pollution and carmakers step up their investments in electric models. To cover its plans for more than 80 new models by 2025, Volkswagen alone is looking for partners in China, Europe and North America to provide battery cells and related technology worth more than 50 billion euros ($59 billion). Talks with major cobalt producers, including Glencore, at VW's Wolfsburg headquarters last week ended without a deal. More than half of the world's cobalt comes from the Democratic Republic of Congo, a country racked by political instability and legal opacity, and where child labor is used in mines. On Wednesday, a group of 10 leading passenger-car and truck manufacturers announced an initiative to jointly identify and address ethical, environmental, human and labor rights issues in raw materials sourcing. The partnership dubbed "Drive Sustainability" consists of VW, Toyota Motor Europe, Ford, Daimler, BMW, Honda, Jaguar Land Rover, Volvo Cars and truckmakers Scania and Volvo. The alliance "will assess the risks posed by the top raw materials (such as mica, cobalt, rubber and leather) in the automotive sector," said Stefan Crets of the CSR Europe business network. "This will allow Drive Sustainability to identify the most impactful activities to pursue" to address issues within the supply chain.Reporting by Andreas Cremer.Related Video: Image Credit: Michael Robinson Chavez/The Washington Post via Getty Images Green BMW Ford Honda Jaguar Land Rover Mercedes-Benz Automakers Toyota Volkswagen Volvo Green Automakers Green Culture Electric Scania ethics mining
