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.

Former NHTSA chief may lead automaker-backed Takata investigation

An automaker-led effort may see the former head of the National Highway Traffic Safety Administration take on the probe into the Takata airbag inflator disaster. A coalition of at least ten automakers is in talks with former NHTSA administrator David Kelly, with unnamed sources familiar with the discussions telling The Wall Street Journal he is "among those we are considering to coordinate" the investigation.The Detroit News, meanwhile, is reporting he could be hired "in the coming days." Takata, the Japanese seatbelt and airbag manufacturer, has been the center of a defect scandal since last year. Takata is under fire for air bag inflators that can explode, shooting out metal and plastic pieces. At least five deaths and dozens of injuries have been linked to the problem worldwide. Earlier this year, Honda Motor Co., the automaker with the biggest exposure to the defective Takata air bags, was fined $70 million in the U.S. for not reporting to regulators some 1,729 complaints that its vehicles caused deaths and injuries, and for not reporting warranty claims. It was the largest civil penalty levied against an automaker. Should he take the role, Kelly would be at the fore of an investigation being assembled by an alliance of ten automakers, which includes the Detroit Three and Honda. Toyota first suggested a joint investigation back in December, The Journal reports. Kelly's goals, meanwhile, will be many. The Detroit News reports that questions abound regarding not only the recalled airbag inflators and the conditions that cause them to fail, but the whether the replacement units will have similar problems in the future. The automaker committee is far from the only one analyzing the airbag issue. Takata has assembled its own panel, led by former Secretary of Transportation Samuel Skinner, while NHTSA's deputy administrator, David Friedman, has brought in an outside engineering firm to investigate the inflators, The Detroit News reports. Separately, on Friday Takata Corp., the Japanese seatbelt and air-bag maker at the center of a defect scandal, is expecting more red ink for the fiscal year through March. It is projecting a 31 billion yen ($264 million) loss, worse than the previous forecast for a 25 billion yen ($214 million) loss, despite higher sales expected for the fiscal year. Ten automakers have recalled about 12 million vehicles in the U.S. and about 19 million globally for problems with the air bags.
