It is a spectacular demonstration! A Saab 9000 CSE with the revolutionary Trionic and a Saab 92 two-stroke engine stand together in the measuring laboratory. First the exhaust behavior of the 9000 Turbo is tested, then the Saab 92 two-stroke starts. What would happen then, nobody would have expected.
The exhaust gases from the two-stroke engine are fed directly into the intake tract of the Saab 9000. It cleans the air and after a short moment the exhaust gas values are as before, when “clean” laboratory air was drawn in. The story is true and verified. In 1992 Saab advertised that a new Saab 9000 with Trionic could clean the air of the metropolitan areas. The customers would only have to buy enough Saabs ...
The Trionic is a milestone in Saab history. Environmental protection was already on the agenda in Trollhättan, before the topic was up to date with other providers. The Swedes had a technical advantage in many things, which became less and less in the following years. The Saab Trionic is history today. The Saab H engine, until recently in use in the 9-5 I, today runs in China from the tapes and could, well, clean Beijing's city air. The Chinese would only have to build and sell a corresponding number.
1992 did not work that way and will only be implemented by decree in China. At least one has experience in it. A comeback of the Trionic is unlikely, because no small manufacturer makes today this luxury. A large part of the automotive world speaks Bosch. And their system is now as clean as the innovation from Trollhättan.
