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 Europe boss says 'reasonable number' of fuel cell vehicles on the way

We know that Toyota is gung-ho about delivering its first hydrogen fuel cell sedan to early-adopter markets like southern California and part of Japan next year. The Japanese automaker's European H2 plans have long been part of the mix, but a new press release shows just how committed Toyota is to hydrogen all around the world. "The volume will be limited, but they will be visible on the streets" – Didier Leroy Toyota says hydrogen fuel cells are a "major, but logical next step" after the company's pioneering work on gas-electric hybrids for 15 years. Didier Leroy, president of Toyota Motor Europe (pictured), said in a statement that he knows there will be H2 hurdles, and so Toyota will start with "a reasonable number of cars" in Europe. "The volume will be limited," he said, "but they will be visible on the streets." Karl Schlicht, Toyota Motor Europe executive vice president, compares Toyota's current hydrogen progress with where the company was with hybrid's in the not-too-distant past. When it comes to infrastructure and cost, he said, "There is of course a long way to go, as with any game-changing technology, but remember the same was said about hybrid only 10 years ago." You can read the full PR below. We don't remember a lot of people saying the infrastructure for hybrids simply wasn't there in 2004, but maybe we missed that memo. TOYOTA EXECUTIVES SET THE SCENE FOR DELIVERING FUEL CELL TECHNOLOGY 16/04/14 from Toyota The next era in Toyota's technology development is about to become production reality, with the market introduction next year of the company's first hydrogen fuel cell-powered car. It's a major, but logical next step for the company, as it builds on the success it has achieved with hybrid over the past 15 years. Karl Schlicht, Executive Vice President of Toyota Motor Europe, is explicit about Toyota's commitment to hydrogen power and the potential of fuel cell vehicles to deliver on the company's ambitions to develop the ultimate eco-car. He says: "Our unique hybrid history and experience have proven invaluable for the next big leap. Back in 2010, we promised our first fuel cell car for 2015 and we are fully on track to honour our commitment. "Fuel cell is a technology that can secure our concept of personal mobility. That's because fuel cells combine the strengths of EVs (electric vehicles) and hybrids, with those of conventional cars.

In Jamaica, it's not easy to sell or buy hybrid cars

Jamaica's mellow reputation and Rasta vibe contributes to an international reputation of an island nation that moves at a leisurely pace. And the term "leisurely" certainly applies to the rate of sales of hybrids there. And we thought Mitsubishi i sales in the US have been slow. The country's Toyota dealership is still in the process of explaining hybrid technology to many of its prospective customers, with the widespread perception remains that a standard Toyota Prius needs to be plugged in for electrical charging, the Jamaica Gleaner reports. Because of such slow exposure, Toyota has only sold about 10 hybrids in Jamaica since the Japanese automaker started selling them there in 2010. And we thought Mitsubishi i sales in the US have been slow. Toyota dealers in Jamaica continue to tout hybrid technology that can boost fuel economy by about 30 percent but are going up against the fact that Toyota's hybrids now need to be pre-ordered and aren't kept in stock because of sluggish demand. There's also the fact that Toyota's Japanese operations insist on an approval process that ensures the hybrids sent there can handle Jamaica's road conditions, and it typically takes three to four months for a Prius to get to Jamaica once ordered. Island locales provide a curious dichotomy for advanced-powertrain vehicles. On one hand, the driving distances tend to be relatively small, lengthening the amount of time it takes to pay back the original cost premium. On the flip side, importing fuel to islands makes gas prices skyrocket and can prove costly for the economy in island nations. Late last year, for instance, the government of another Caribbean nation, Barbados, estimated it spends about $250 million a year on gas used for personal vehicles. That's why the government there is pushing for more electric-vehicle adoption, though the number of EVs on the island was in the low double-digits as of mid-2013.
