Actually, my work began with tasks in exhaust gas removal. At that time, it was simply important to discharge exhaust gases as quickly as possible.
The actual measurement technology and legal requirements were still in their infancy.

No one had a little Swedish girl with pigtails on her neck.

A simple task like coupling hoses and adaptations reasonably had to be bought expensively in the USA.

One day, when I was still working on the test benches at Daimler as a newly self-employed person, I was asked if I could come up with something.

And indeed, it became bright in the room, I had an idea and implemented it. Even today, the final form of it is an integral part of our exhaust gas removal concept and the many variants in our portfolio.
