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.

Consumer Reports criticizes small turbo engines for misleading performance, fuel economy claims [w/video]

Consumer Reports has taken aim at at small-displacement, forced-induction engines, saying the powerplants don't manage to deliver on automaker fuel economy claims. Manufacturers have long held that smaller, turbocharged engines pack all power of their larger displacement cousins with significantly better fuel economy, but the research organization says that despite scoring high EPA economy numbers, the engines are no better than conventional drivetrains in both categories. Jake Fisher, director of automotive testing for Consumer Reports, says the forced induction options "are often slower and less fuel efficient than larger four and six-cylinder engines."
Specifically, CR calls out the new Ford Fusion equipped with the automaker's Ecoboost 1.6-liter four-cylinder engine. The institute's researchers found the engine, which is a $795 option over the base 2.5-liter four-cylinder, fails to match competitors in acceleration and served up 25 miles per gallon in testing, putting the sedan dead last among other midsize options.
The Chevrolet Cruze, Hyundai Sonata Turbo and Ford Escape 2.0T all got dinged for the same troubles, though Consumer Reports has found the turbo 2.0-liter four-cylinder in the BMW 328i does deliver on its promises. You can check out the full press release below. You can also read the full study on the Consumer Reports site, or scroll down for a short video recap.

Detroit Three to lose dominance of North American auto output in 2017

DETROIT — North American vehicle production by the unionized Detroit Three automakers will fall behind the combined North American output of Tesla and automakers from Europe and Asia for the first time this year, IHS Markit forecast on Wednesday. In 2017, the Detroit Three could build 8.6 million vehicles in North America, while Tesla and foreign automakers build 8.7 million, IHS Markit analyst Joe Langley said. By 2024, the gap will widen, with Asian and European automakers and Tesla combining to build about 9.8 million vehicles in North America. General Motors, Ford and the North American operations of Fiat Chrysler Automobiles NV will combine to build 8.1 million vehicles, down 6 percent from this year. Mexico is on track to increase its share of North American vehicle production, Langley said, moving to 4.5 million vehicles a year by 2024 from about 4 million vehicles currently. The milestone for the growth of Tesla and foreign automakers in North America comes as the Trump administration is pushing to limit imports of vehicles from Mexico in negotiations to overhaul the North American Free Trade Agreement. The declining share of North American vehicle production for the Detroit automakers also challenges U.S. and Canadian unions that represent their workers. Canadian workers are on strike at a GM factory in Ontario to protest the automaker's decision to cut jobs and move to Mexico some production of sport utility models built there. Foreign automakers over the past year have announced plans for a wave of new or expanded plants in North America, while Tesla is ramping up to build as many as 500,000 cars a year at its plant in Fremont, Calif. Often referred to as "transplants," the foreign-owned factories are poised to become the mainstream of the North American auto industry. Automakers are increasingly using factories in China or Mexico to build vehicles that used to be assembled solely in the United States, Langley said. He cited as an example Ford's decision to shift production of the Focus small car for North America to a Chinese assembly plant.
