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.

Weekly Recap: GM posts solid profits, not looking for partners

General Motors is not looking for partners. It's big enough already. So says CEO Mary Barra, who shot down overtures from outspoken Fiat-Chrysler chief Sergio Marchionne this week. Barra said GM will look to find scale within its operations, rather than through outside partners. "We think there's tremendous opportunity for us within the business as we look at efficiency measures, as we look at truly achieving the scale that we should have, because we're already in that top tier of the auto industry among the largest OEMs," she said. Barra added: "We have a very well-articulated plan. We're in the middle of executing that, and we're not going to entertain anything that might distract us from accomplishing that." Her remarks came in the wake of Marchionne's provocative comments in March. He expects a wave of industry consolidation and said he's open to teaming with Ford or GM, calling it "technically feasible." Because of its smaller size, FCA would likely stand to gain more from a partnership than GM or Ford. The Blue Oval isn't interested in teaming with Fiat-Chrysler, either. "We have no other plan or interest then to continue to accelerate our One Ford plan, deliver product excellence and drive innovation in every part of our business," a spokesperson said. GM, the largest US automaker, announced a $945-million first-quarter profit on Thursday and posted its best earnings performance in North America since 2009. Earlier in the week, GM confirmed it had sold 2.4 million vehicles around the world in the quarter, ranking behind Toyota (2.52 million) and Volkswagen (2.49 million). Other News & Notes SUVs, EVs shine at Shanghai Motor Show SUVs and electric vehicles grabbed the spotlight at the Shanghai Motor Show this week as companies vied for attention in the world's largest car market. Notably, Honda's Concept D previewed the company's future flagship SUV that's being developed for China, Mercedes rolled out a BMW X4-fighting GLC Coupe concept and Chinese company Qoros debuted its 2 plug-in SUV concept. Nissan, Volvo and several others also showcased utility vehicles in Shanghai. Automakers are rushing to take advantage of the crossover craze in China. The market for locally-produced SUVs grew 50 percent in the first quarter, according to IHS Automotive research, which called the show a "launch pad" for new utility vehicles. Even though SUVs are popular, IHS predicts their growth rate will slow, and sedans account for more sales volume in China.

U.S. automakers unite in opposition to possible Trump vehicle tariffs

WASHINGTON — The U.S. auto industry urged President Donald Trump's administration on Monday not to saddle imported cars and auto parts with steep tariffs, after the U.S. Commerce Department sent a confidential report to the White House late on Sunday with its recommendations for how to proceed. Some trade organizations also blasted the Commerce Department for keeping the details of its "Section 232" national security report shrouded in secrecy, which will make it much harder for the industry to react during the next 90 days Trump will have to review it. "Secrecy around the report only increases the uncertainty and concern across the industry created by the threat of tariffs," the Motor and Equipment Manufacturers Association said in a statement, adding that it was "alarmed and dismayed." "It is critical that our industry have the opportunity to review the recommendations and advise the White House on how proposed tariffs, if they are recommended, will put jobs at risk, impact consumers, and trigger a reduction in U.S. investments that could set us back decades." Representatives from the White House and the Commerce Department could not immediately be reached. The industry has warned that possible tariffs of up to 25 percent on millions of imported cars and parts would add thousands of dollars to vehicle costs and potentially devastate the U.S economy by slashing jobs. Administration officials have said tariff threats on autos are a way to win concessions from Japan and the EU. Last year, Trump agreed not to impose tariffs as long as talks with the two trading partners were proceeding in a productive manner. "We believe the imposition of higher import tariffs on automotive products under Section 232 and the likely retaliatory tariffs against U.S. auto exports would undermine - and not help - the economic and employment contributions that FCA, US, Ford Motor Company and General Motors make to the U.S. economy," said former Missouri Governor Matt Blunt, the president of the American Automotive Policy Council. Some Republican lawmakers have also said they share the industry's concerns. In a statement issued on Monday, Republican Congresswoman Jackie Walorski said she fears the Commerce Department's report could "set the stage for costly tariffs on cars and auto parts." "President Trump is right to seek a level playing field for American businesses and workers, but the best way to do that is with a scalpel, not an axe," she added.
