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.

The next steps automakers could take after sales drop again in April

DETROIT (Reuters) - Major automakers on Tuesday posted declines in U.S. new vehicle sales for April in a sign the long boom cycle that lifted the American auto industry to record sales last year is losing steam, sending carmaker stocks down. The drop in sales versus April 2016 came on the heels of a disappointing March, which automakers had shrugged off as just a bad month. But two straight weak months has heightened Wall Street worries the cyclical industry is on a downward swing after a nearly uninterrupted boom since the Great Recession's end in 2010. Auto sales were a drag on U.S. first-quarter gross domestic product, with the economy growing at an annual rate of just 0.7 percent according to an advance estimate published by the Commerce Department last Friday. Excluding the auto sector the GDP growth rate would have been 1.2 percent. Industry consultant Autodata put the industry's seasonally adjusted annualized rate of sales at 16.88 million units for April, below the average of 17.2 million units predicted by analysts polled by Reuters. General Motors Co shares fell 2.9 percent while Ford Motor Co slid 4.3 percent and Fiat Chrysler Automobiles NV's U.S.-traded shares tumbled 4.2 percent. The U.S. auto industry faces multiple challenges. Sales are slipping and vehicle inventory levels have risen even as carmakers have hiked discounts to lure customers. A flood of used vehicles from the boom cycle are increasingly competing with new cars. The question for automakers: How much and for how long to curtail production this summer, which will result in worker layoffs? To bring down stocks of unsold vehicles, the Detroit automakers need to cut production, and offer more discounts without creating "an incentives war," said Mark Wakefield, head of the North American automotive practice for AlixPartners in Southfield, Michigan. "We see multiple weeks (of production) being taken out on the car side," he said, "and some softness on the truck side." Rival automakers will be watching each other to see if one is cutting prices to gain market share from another, he said, instead of just clearing inventory. INVESTORS DIGEST BAD NEWS Just last week GM reported a record first-quarter profit, but that had almost zero impact on the automaker's stock. The iconic carmaker, whose own interest was once conflated with that of America's, has slipped behind luxury carmaker Tesla Inc in terms of valuation.
