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: Toyota propels hydrogen fuel cells

Toyota is serious about hydrogen fuel cells, and it wants the auto industry to follow suit. The Japanese automaker said this week it's releasing 5,680 fuel cell patents from around the world, including technologies used on its upcoming sedan, the 2016 Mirai. The move is unusual, but not unprecedented, as Tesla similarly released its electric vehicle patents last year. The idea for Tesla, and now for Toyota, is to spur development of alternative propulsion. "By eliminating traditional corporate boundaries, we can speed the development of new technologies and move into the future of mobility more quickly, effectively and economically," said Bob Carter, Toyota Motor Sales senior vice president of automotive operations, in a statement. Toyota's fuel cell patents will be free to use through 2020, though patents related to producing and selling hydrogen will remain open forever. Toyota said it would like companies that use its patents to share their own hydrogen patents, but won't require it. "What Toyota's doing is really a logical move, and really a good move for the industry," Devin Lindsay, principal powertrain analyst with IHS Automotive, told Autoblog. The announcement was made at the Consumer Electronics Show in Las Vegas. It comes as Toyota prepares to launch the hydrogen-powered Mirai in a limited number late this year in California. The launch will be extended to the Northeastern United States next year. Toyota also has announced plans to support networks of fueling stations in each region to try to smooth consumer adoption. The Mirai has a 300-mile range on a tank of hydrogen, and it takes about five minutes to refill. Fuel cells have been receiving increased attention recently, and Audi and Volkswagen debuted hydrogen-powered cars at the 2014 Los Angeles Auto Show. Honda, another proponent of the technology, also showed its updated FCV concept in November in Japan. The company, however, has delayed its fuel cell sedan a year until 2016. Like Toyota, Honda says its hydrogen-powered car will have a range of 300 miles or more. Meanwhile, Hyundai currently offers leases for fuel-cell powered Tucsons, which have a 265-mile range, in Southern California. Despite the optimism some automakers have for fuel cells, the technology still faces barriers. A lack of filling stations has long held it back, and many consumers are not familiar with the potential benefits.

Weekly Recap: Volkswagen moves forward under Muller

Most stunning was the speed of it all. On the morning of September 18, Volkswagen AG stood atop the automotive world. It was profitable and sold more cars than Toyota and General Motors, its two main rivals for global supremacy. By nightfall, the company would be embroiled in scandal. Revelations the German auto giant cheated on diesel emissions testing in the United States reverberated from Washington to Wolfsburg, Germany. What started out as a problem with 482,000 VWs and Audis in the US exploded into an international scandal. Millions of vehicles have the rigged software, meaning VW broke environmental rules as its cars spewed pollutants all over the world. The fallout began immediately. Volkswagen CEO Martin Winterkorn – one of the most respected and capable executives in the business – apologized on Sunday and Tuesday. On Wednesday he resigned. As the week progressed, the company's stock took a beating and credit agencies threatened to drop their ratings. VW dealers and owners said they felt betrayed. The automaker hired a law firm that defended BP after the Deepwater Horizon oil spill. The EPA is already extending its testing procedures to look for "defeat devices" like the ones used by Volkswagen. On Friday the company announced a major restructuring. Matthias Muller, Porsche's chief for the last five years, took over as CEO of Volkswagen and is charged with picking up the pieces of a shattered company facing regulatory action and lawsuits. With GM, Toyota, and Takata scandals still fresh, Volkswagen will likely experience unprecedented levels of scrutiny. Additionally, VW's markets in the United States, Canada, and Mexico will be combined into a North American region under the leadership of former Skoda boss Winfried Vahland, though US chief executive Michael Horn will stay on. The company is also realigning its brands by specialty and streamlining its board. Firings, government action, restructurings, and international outrage – things that usually build up over months or years – all occurred in about a week. With dizzying speed, Volkswagen's future has changed dramatically. It all happened, it's still happening, so fast.
