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.

Toyota and Suzuki are looking at an R&D partnership because they admit they're behind

The Chairman of Suzuki Motor Corporation, Osamu Suzuki, and the President of Toyota, Akio Toyoda, have convened at Toyota's Tokyo offices to declare plans to join hands regarding research and development. According to Toyoda, Toyota "hasn't been good at creating alliances," and its partnership with the small carmaker Daihatsu has been the most well-known collaboration so far. Perhaps the comment has a tinge of regret from Toyota and GM's NUMMI days in Fremont, especially as the statement released by Toyota says that "Toyota is conscious of the fact that it may be behind competitors in North America and Europe when it comes to the establishment of standardizations and partnership with other companies." But as different technologies advance at breakneck speed and it is difficult for companies both big and small to stay competitive, let alone ahead of the game, Toyota is accepting the need for collaboration. Toyoda referred to passenger safety, environmental issues, automated driving, and hydrogen technology, all of which are key challenges for any carmaker looking to stay relevant, and all expensive to experiment with. Spreading the cost over more vehicles should help. "We received an offer from Suzuki regarding collaboration possibilities on advanced and future technologies such as in information technology. Suzuki made a frank proposal to us, and in understanding that Toyota is facing the challenges which I had mentioned earlier, we thought that with the relationship between both companies, there is an opportunity for a business partnership to help solve such challenges. As such, we decided to explore such possibilities together," said Toyoda. In the future, Daihatsu will still be Toyota's tool in emerging markets, but now Toyota could have access to Suzuki's small-car know-how. Osamu Suzuki acknowledges that "Suzuki's current business focuses on minivehicles in Japan and India," as Suzuki withdrew from the US and Canada in 2013. A joint effort will help Suzuki remain relevant, and as a manufacturer of predominantly small vehicles it has been focusing on competitive pricing more than cutting edge technology. Related Video:

Alonso can do full WEC season after date changed to avoid F1 race

McLaren Formula One driver Fernando Alonso can compete for Toyota in every round of the World Endurance Championship this season after organizers moved the Japanese event to avoid a U.S. Grand Prix clash. They announced at a presentation in Paris on Friday that the Six Hours of Fuji had been brought forward to Oct. 14, ensuring that the Spaniard can feature for Toyota at the manufacturer's home track. Alonso wants to win the Le Mans 24 Hours endurance race in France as part of the "triple crown of motorsport" achieved only by the late Briton Graham Hill. Hill, like Alonso a two-times Formula One world champion, won Le Mans, the Monaco Grand Prix and the Indianapolis 500 in the 1960s and early 1970s. Toyota announced last month that Alonso, whose main focus remains Formula One, would be racing all the rounds of the endurance season that did not clash with his McLaren commitments. The Fuji race had originally been pushed back a week to Oct. 21 to avoid a clash with the IMSA Petit Le Mans round at Road Atlanta in the United States. The eight round 2018-19 WEC "super season" includes two editions of Le Mans as a move towards a championship that will start in the European summer and end with the French endurance classic. The top LMP1 category will have 10 cars, with Toyota the only factory team following the departure of reigning champions Porsche. Alonso will share a car with Switzerland's Sebastien Buemi and Japanese Kazuki Nakajima, both former F1 drivers. Reporting by Alan Baldwin Related Video:
