The week is very petrol, promised! Almost no electric cars, and we strive for balanced coverage. Because the world of mobility is changing rapidly, we are starting with the revolutions that are coming. And somehow everything has to do with Saab at the end - at least a little bit. We blind ourselves to the past. The times were rough in the year 2011. The focus of public attention has always been Eric Geers, Director Communication of Saab Automobile AB.
What he had to say was mostly not good news, and he was not envied for his job. But he was always sovereign; Looking back, I feel great respect for his performance. After Saab came Qoros and more than 3 years China. Qoros is for him, as for many Europeans, past. Maybe a bit early. At the end of the article more.
For Geers, who has since founded his own communications company, there is a new challenge. It's electric, so extreme that it could be better described as electrifying.
Geers works for Techrules, a Chinese company working on next generation high performance electric vehicles. It focuses on power density, the ability to deliver peak power, and not energy density. The system uses a serial hybrid drive with turbine generator that generates power as a range extender from a microturbine. The first development prototype is 768 KW / 1.044 PS, regulated at 350 km / h, and has a range of more than 2.000 kilometers. In plug-in mode, only 0,18 liters are to be consumed on 100 kilometers. Kerosene - not a common gasoline, because much of this new technology comes from the aircraft industry.
The thing with the turbine generator, which is supposed to bring a consumption advantage of 50% to the conventional range extender, is interesting and not a fantasy. The production version is supposed to cover 150 kilometers with batteries, then the range extender of the high-performance athlete steps in. Techrules is currently exploring production sites in Europe and plans to start manufacturing in the EU in 3 years with the series product. This press release provides detailed information on exciting technology with an aircraft background.
A turbine generator as a range extender would fit well with the Saab brand if it made a comeback. It would be the beginning of an exciting revolution. As it once was the turbo - but also not past.
Why the turbo lives on.
Modern 3-Wege catalysts achieve in the NOxConversion efficiencies by 99%. This is not enough for the future; the missing percent must be eliminated as completely as possible in order to meet future standards. To secure the future, there is a new solution for Otto Turbo Engines. She comes from Germany from Continental. The Niedersachsen were partners of NEVS before the reconstruction. Whether it is still the case, we do not know, Trollhättan is far.
The magic word: ring catalyst. Simply put, there is a ring inside the catalyst that extends the length of the pipe. This allows the catalyst to be placed very close to the engine, the temperature to the NOxConversion is achieved faster, the wastegate gas from the turbocharger contributes to better exhaust gas mixing in the inner tube. Continental speaks of almost 100% conversion, the details are here) accessible.
Turbo engines are getting cleaner, and while the future should be electric, why not dream of a turbo made by Trollhättan? Or from a turbine engine. Or from another Swedish innovation.
Why Qoros lives on
Some Swedish media have in the past described Qoros as an alternative for Saab drivers ... back when there were still European plans. Why this was so, has never opened to me. Perhaps they could never suffer Saab, which was the case with some large-edition sheets, at least.
Qoros delivers rock solid goods and is now unusually innovative. At the Beijing Auto Show, the Chinese show a concept vehicle without camshafts for the first time. The valve drive is electrohydraulic; Camshafts, timing belts and throttle valves fall away. The engine shallower, the consumption is lowered, the power increases.
The innovation is not from China, it comes from Ängelholm. The Koenigsegg subsidiary FreeValve AB is responsible for the development, it was first tested in a Saab engine. Another smart innovation that would have worked well with Saab. In the years from 2010 to 11, there were some fantasies for a possible use in a new generation of Saab vehicles. With the maturity of the series, one can see that Saab is no longer there, celebrating the innovation in Chinese vehicles premiere. A success for Ängelholm - with a sad aftertaste. The details are on the Koenigsegg Blog read by Steven Wade.
Is the turbo dead? The burner? Is the microturbine the exciting alternative? Optimizations show what is possible. The drives of the future will be more diverse than we can imagine.
