Recharge Wrap-up: Toyota HQ goes solar, CARB fights methane

Opel denies allegations about illegal emissions software as the German transport ministry begins its review. Opel has turned documents over to German authorities, and promises to hold a "constructive dialogue" while answering any lingering questions, says the automaker. Opel says that "the allegations reflect a wrong understanding of how diesel engines work." As German magazine Der Spiegel renewed questions about a cheat device similar to those used by Volkswagen, Opel reiterates, "We do not have any software that recognizes whether a vehicle is undergoing an exhaust emissions test."

French industrial gases company Air Liquide manufactures liquid hydrogen, while Korean automaker Hyundai has already deployed its Tucson Fuel Cell crossover in select markets around the world. The two companies have signed a deal to cooperate on hydrogen technology. President Park visited an Air Liquide research center during a trip to Europe, where she said that a partnership between Hyundai and Air Liquide can help their countries stay ahead in the fuel cell vehicle market.

The system, treatment, operation, and device standards would apply to onshore and offshore oil and gas production, storage, processing, and transmission facilities, covering procedures for leak detection and repair, equipment replacement, record keeping, and data reporting. "Methane emissions from the oil and gas industry contribute to California's [greenhouse gas] emissions and cost-effective reduction opportunities already exist and are available for use in the sector," CARB says. "In addition, reducing methane emissions from this sector will help slow the rate of climate change in the near-term and have an immediate beneficial impact on climate change." A hearing is scheduled for July 21 to discuss the proposal. Read more from SNL. Toyota's new Plano, Texas campus will get 25 percent of its energy from the sun. As Toyota plans to move into its new North American headquarters next year, it is building a 7.75-megawatt solar system to provide renewable energy for its operations. The solar arrays will be built atop three parking structures by the end of 2017.

Toyota R&D shows off free piston engine linear generator for future EVs

We often hear how an electric vehicle powertrain architecture allows vehicle designers much more freedom than a traditional ICE powertrain does. With differently shaped battery modules and small electric motors, there are lots of way to put the pieces together. With today's plug-in hybrid technology, engineers still need to put a decent-sized ICE somewhere, but new technology from Toyota could free up the gas-electric vehicle designers of the future. Presented at the recent SAE World Congress in Detroit, the idea from Toyota Central R&D Labs Inc. and involves what is called a Free Piston Engine Linear Generator (FPEG). Think of it as a sort of one-cylinder, two-stroke mini-engine that can work either as a generator (thank to magnets and a linear coil) or to directly drive a vehicle. The current prototype is a 10-kW unit that Toyota say would provide enough power to get a B- or C-segment electric vehicle up to highway speeds (75 miles per hour) when paired up to offer 20 kW. Pairing the FPEGs is also important to minimize vibrations. One system tested by Toyota had a 42 percent thermal efficiency, but the engineers are working to improve the overall efficiency even further. You can watch an animated video of the piston in action here (click on "Outline") and see the SAE papers here and here. More technical details are available at Green Car Congress.

US expands probe into ZF-TRW airbag failure-to-deploy to 12.3 million vehicles

DETROIT — U.S. auto safety regulators have expanded an investigation into malfunctioning airbag controls to include 12.3 million vehicles because the bags may not inflate in a crash. The problem could be responsible for as many as eight deaths. Vehicles made by Toyota, Honda, Kia, Hyundai, Mitsubishi and Fiat Chrysler from the 2010 through 2019 model years are included in the probe, which was revealed Tuesday in documents posted by the National Highway Traffic Safety Administration. It involves airbag control units made by ZF-TRW that were installed in the vehicles. The control units can fail in a crash, possibly because of unwanted electrical signals produced by the crash itself that can disable an air bag control circuit housed in the passenger compartment, according to NHTSA documents. The electrical signals can damage the control circuit, the documents say. ZF, a German auto parts maker which acquired TRW Automotive in 2015, said in a statement that it's committed to safety and is cooperating with NHTSA and automakers in the investigation. The case is another in a long list of problems with auto industry airbags, including faulty and potentially deadly Takata airbag inflators. At least 24 people have been killed worldwide and more than 200 injured by the inflators, which can explode with too much force and hurl dangerous shrapnel into the passenger cabin. The inflators touched off the largest series of automotive recalls in U.S. history involving with as many as 70 million inflators to be recalled by the end of next year. About 100 million inflators are to be recalled worldwide. On April 19, NHTSA upgraded the ZF-TRW probe from a preliminary evaluation to an engineering analysis, which is a step closer toward seeking recalls. So far, only Hyundai and Kia and Fiat Chrysler have issued recalls in the case. Four deaths that may have been caused by the problem were reported in Hyundai-Kia vehicles and three in Fiat Chrysler automobiles. NHTSA opened an investigation in March of 2017 involving the TRW parts in Hyundais and Kias. The upgrade came after investigators found two recent serious crashes involving 2018 and 2019 Toyota Corollas in which the airbags did not inflate. One person was killed. Jason Levine, executive director of the Center for Auto Safety, a nonprofit consumer group, said the ZF-TRW case shows the auto industry thus far has learned very little from Takata.
