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.

Union to launch Toyota organization drive in Canada

Toyota may be heading toward some labor issues in the Great White North, as employees at a pair of Canadian Toyota factories may be set for a certification vote. The Unifor union, which was the result of a merger last year between the Canadian Auto Workers and the Communications, Energy and Paperworkers union, will be holding the vote.
Over 40 percent of the employees at the Woodstock and Cambridge, Ontario factories have signed union cards, cresting the minimum percentage required to instigate a legal certification vote, according to Reuters. The Woodstock factory is responsible for RAV4 production, while Cambridge builds the Lexus RX350 and RX450h, as well as the Toyota Corolla. The two factories employ nearly 7,000 people.
It's unclear when the union will hold a certification vote at the two factories, but what is rather clear are the worker complaints. Employees are concerned about workers being hired on temporary contracts which lack the benefits of full employment, John Aman, head of organizing for Unifor, told Reuters.

Rod Millen to face Monster Tajima in Electric Division of Pikes Peak Hill Climb

The 91st running of the Pike's Peak International Hill Climb is scheduled to begin on June 30. Like last year's event, the 12.42 mile course - fully paved these days - starts at 9,390 feet elevation and doesn't stop climbing until it reaches an impressive 14,110 feet (the air is so thin up there that the FAA requires pilots to use oxygen at that altitude).
There will be an assortment of internal combustion machines racing to the summit, entries from France, Italy, Japan, Latvia, Sweden, Brazil, Canada, Great Britain, Hungary, Czech Republic, Poland and Belgium, but all eyes will be on the electric showdown between Rod Millen and Nobuhiro "Monster" Tajima, from Japan. 61-year-old Millen is a familiar name to Toyota racing fans, and he will be driving the Toyota TMG EV P002 (it won the Electric title last year), while Tajima will be again piloting the Monster Sport E-Runner (which was forced out of the field last year after a fire broke out).
Other entrants include Rhys Millen driving a 2013 Hyundai PM58OT and Paul Dallenbach, who will be driving Millen's Hyundai Genesis Coupe (it set the all-time speed mark last year).
