1. Approval


Gtr development for h2 and fc vehicles a t v s d opinion

One of the most important Rules in Safety Technology:

Prevention is better than cure

Abteilung:


Gtr development for h2 and fc vehicles a t v s d opinion

  • Someexperiences in the last 5 yearswith CNG- and LPG-vehicles in Europe:

  • - 6 burstincidents (Saarland-CNG, Recklinghausen-LPG, Emmendingen-LPG, Speyer-LPG, Brescia-CNG, France-CNG)

  • - reasons: positionof PRD, LPG-tank was filledat a CNG-station, missing PRD, failingsolenoidvalve, toosmallorificeof PRD-ventline

  • 3 crashincidentswith LPG-vehicles (Rinteln, Dülmen, Thalwil-CH)

  • Noburstofcontainers
