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.

Total auto recalls already on record pace in 2014

If you've noticed that there have been more recalls than usual this year, you may be on to something. According to a report from the National Highway Traffic Safety Administration, the US market is on pace to break a record for recalls. In 2013, 22 million cars were recalled. We're only a third of the way through 2014, though, and we've already halved that figure, with 11 million units recalled. That's wild.
Considering the past few months, it shouldn't be a surprise that General Motors is leading the charge, with six million of the 11 million units recalled coming from one of the General's four brands. Between truck recalls, CUV recalls and the ignition switch recall, 2014 hasn't been a great year for GM.
Other recall leaders include Nissan (one million Sentra and Altima sedans), Honda (900,000 Odyssey minivans), Toyota (over one million units in a few recalls), Volkswagen (150,000 Passat sedans), Chrysler (644,000 Dodge Durango and Jeep Grand Cherokee SUVs) and most recently, Ford (434,000 units, the bulk of which were early Ford Escape CUVs). So while it's been a bad year for GM so far, its competitors aren't doing too well, either.

119K Toyota Avalon sedans recalled over airbag woes

Toyota has issued a voluntary safety recall for 119,000 2003-2004 Avalon models because in some cases the airbags could inadvertently deploy.
The automaker says that circuits within the airbag control module could be damaged by electrical noise, which could cause the front airbags and seatbelt pre-tensioners to activate. Dealers are going to repair cars by adding an electrical noise filter to the module. Owners will be notified by first class mail.
Toyota Public Affairs Manager Cindy Knight told Autoblog that there was one reported injury caused by the sudden deployment, but there have been no accidents or crashes. The company is currently preparing the parts for dealers now, and the component takes 90 minutes to two hours to install. "We don't believe there are any other affected models," said Knight.
