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 profits up 23% on high US sales, despite mounting legal costs

Toyota earned $9.3 billion in net income in the financial year that ends next month. The number beats earlier forecasts and marks a five-year high for the automaker, with both operating income and revenue up by 9.5 percent and 2.5 percent, respectively. Toyota saw quarterly profit enjoy a year-on-year jump of 23.4 percent, with the manufacturer earning more than $1 billion between October and December 2012. The good news comes in spite of the fact that the Japanese automaker actually endured an operating loss in North America, due in part to legal fees.
Toyota is set to pay more than $1 billion to owners who claim their vehicles decreased in value as a result of the company's recent spate of recalls. Even so, all three of the automaker's brands enjoyed a 13.5 percent sales increase in the US in the last quarter, beating the industry average. Toyota faltered in Europe, however, where it earned $99 million in operating profit last year, compared to $111 million in 2011. You can take a closer look at the company's full press release below for more information.

Shuttle-hauling Tundra finds permanent home in science exhibit

The idea of lifting a full-size pickup truck completely off the ground by hand might seem as likely as, say, said pickup truck towing a 150,000-pound space shuttle, but... hurray, physics! The same Toyota Tundra that towed the Space Shuttle Endeavour to its final resting place at the California Science Center is now on permanent display there as an exhibit that shows how a lever works.
Like all levers, this exhibit uses a fulcrum allowing people other than Superman to lift the 5,625-pound pickup (plus an extra 1,000 pounds for the rig). That's almost as impressive as the Tundra pulling 17 times its rated towing capacity back in October. Regardless, Toyota is once again cashing in on the publicity stunt and visitors to the science center get a live demonstration of a simple machine - we call that a win-win.
