British company Controlled Power Technologies (CPT) has announced the development of a belt-driven Integrated Starter Generator (B-ISG) that provides stop-start functionality. CPT claims that it suited for both gasoline and diesel engines, up to 3 and 2.5 liters respectively. CPT's SpeedStart device uses a liquid cooled switched reluctance (SR) electrical machine, coupled to power electronics, and is contained in a single housing. The unit is sold as a "very robust production-ready plug-and-play
Stop & Start technology, also known as mild hybrization, is a relatively simple technology that can easily reduce fuel consumption in vehicles. Regular readers already know how it works. Basically, in most instances, the engine shuts down instead of idling, for instance at traffic lights, and stores enough energy to start right back up when the driver presses the gas pedal or shifts into the first gear. This technology can now be found in most car types, and is especially popular in Europe.
I guess that at this point we've pretty much lost track of how many "green labels" automakers have slapped on their cleanest European vehicles (see Econetic, eco2, et al.). These labels are created to highlight the least-polluting member of a car line, usually based on the most basic engine configuration. When it comes to Japanese automakers, green badging was lagging behind the Europeans, but Mitsubishi is trying to catch up with a new name: Cleartec.
Peugeot Citroën's overall sales were down seven-tenths of a percent last year, but the Citroën C4 Picasso was launched successfully last October. That's good to hear, as I've been paying special attention to news about the C4. The reason I'm excited about C4 news is that potential of the C4 prototype that we learned about last year. The prototype features something called Stop & Start technology, which shuts the diesel-hybrid engine down when the car stops moving and automatically
