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.

2016 Ford Explorer revealed with new 2.3-liter EcoBoost

A 2.3L EcoBoost four-cylinder takes over where the old 2.0 left off, making 270 hp and 300 lb-ft.
Right now, around 23 percent of all Ford vehicles sold in the United States is a utility vehicle. By 2020, Ford expects that figure to increase all the way to 29 percent. Put simply, SUVs and crossovers are very big business at Ford. So, when it comes time to update the Explorer, Ford's original sport utility vehicle, you can be sure that a whole heck of a lot of effort goes into the process.

Recharge Wrap-up: Atieva making EV with former Tesla talent, Holland lowers PHEV incentives

A reduction of tax incentives on company cars in Holland is expected to put the brakes on plug-in hybrid sales. Cars are taxed at an average of 25 percent, with plug-in hybrids taxed at just seven or 14 percent, depending on emissions. Taxes on PHEV company cars will increase to 14 and 21 percent. With company car leases making up a third of vehicle sales in 2014, the uptake on PHEVs "will likely go back to regular volumes," according to Volvo's Christiaan Krouwel. It could be a boon for battery electric cars, as their tax rate will remain at four percent for company cars. Read more at Automotive News Europe. Ford is testing cylinder deactivation in its 1.0-liter EcoBoost engine. On-road prototype testing has shown improvements in fuel economy of as much as six percent. Ford engineers developed a system using a new dual mass flywheel, pendulum absorber, and tuned clutch disc to allow cylinder deactivation under a wider range of speed and engine loads with less NVH. "The highest priority in the development of new combustion engines for automotive applications is the ongoing reduction of fuel consumption," says Ford's Andreas Schamel, presenting Ford's findings to the Vienna Motor Symposium. Read more at Green Car Congress or in the press release from Ford. Atieva is building an EV with the help of numerous former Tesla employees. The Silicon Valley-based startup was founded in 2007 by a former Tesla vice president, and its roster includes 12 other former Tesla employees. Already well funded, Atieva is now looking to fill its ranks with more talent, with 32 engineering positions, two recruiter positions and other job openings posted at its website. As for the EV it is working on, Atieva says it is "redefining what a car can be, by building an iconic new vehicle from the ground up." Read more at Charged EVs. Testing shows that Joule ethanol, made from recycled CO2, meets standards for use in the US and Europe. In partnership with Audi, Joule has been working toward making its recycled CO2 fuels ready for commercialization. "We are pleased to achieve another critical step towards our planned near-term delivery of fuel-grade ethanol from recycled CO2," says Joule President and CEO Serge Tchuruk. "Using waste CO2 as a feedstock, our technology has the two-fold advantage of reducing greenhouse gas emissions and producing cost-competitive, drop-in fuels." Joule will use these test results to get government approval for the use of its ethanol in highway fuel.
