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's Texas move could boost state's economy by $7.2B in 10 years

They say everything is bigger in Texas, and apparently that includes the Toyota's effect on the economy. The giant Japanese automaker's new headquarters in Plano, TX, will add an estimated $7.2 billion to the state over the next 10 years, according to a new study commissioned by the city and cited by Bloomberg.
The benefits appear to be an absolute steal compared to the direct incentives that Plano and the state are giving Toyota. The report finds that by the time the automaker's campus is complete in 2018, it could have 3,650 full-time workers there at an average salary of $104,000. The city has prepared $6.75 million in grants, plus property tax discounts, according to Bloomberg. In addition to that, the state is offering the business $40 million in incentives from its Texas Enterprise Fund. This is still a fraction of what Toyota is estimated to bring in.
Toyota announced in April that it would move its US operations to Plano after being headquartered in California since 1957. The move affects thousands of employees from the sales and engineering divisions. The first workers will arrive there this fall, but Toyota will eventually have a whole campus in Plano by late 2017. The move is expected to save it huge amounts in taxation and offer employees a lower cost of living. Toyota North America CEO Jim Lentz also says that the Texas location puts the headquarters closer to more of the business' factories in the south. Texas certainly appears to be showing it some southern hospitality.

Toyota unveils two new small displacement engines

Toyota introduced a pair of brand-new engines in Japan today, that it says will eventually spawn 14 different variants by 2015. Where these two engines stand out in today's world, is that neither mill boasts direct injection, and both are naturally aspirated.
The larger of the two is a 1.3-liter, while the smaller engine, a 1.0-liter, was developed in collaboration with Daihatsu. What makes these two unique is that they both use the Atkinson cycle. Now, we aren't going to bore you by explaining just what this is - there's Google for that. Suffice it to say, Atkinson engines are highly efficient, but that efficiency comes by sacrificing power. That's why they're so popular in hybrids, which can offset the power losses.
This focus on fuel efficiency extends throughout the new engines, which also benefit from tweaks like a cooled exhaust gas recirculation system and a trick intake port, while the 1.3 employs Toyota's iE variant of variable valve timing. Both engines can be fitted with stop-start tech. According to Toyota, when fitted with stop-start the 1.3 should provide around a 15-percent bump while the 1.0-liter will increase economy around 30 percent, when they arrive on the road.
