Back in Berlin, Reinhard Heydrich immediately set to work within the RSHA for the development of, in the words of Heydrich's subordinate Walter Rauff, a "more humane method of execution" than the "Einsatzgruppen" firing squads which had been used. When a prototype gas van was driven to KTI, Widmann explained to his young chemists that by adjusting the timing of the ignition, one could maximize the amount of poisonous carbon monoxide in the

The exhaust gas temperature is 1000 degrees Fahrenheit in normal operation and 1800 Fahrenheit at full power. Exhaust is directed upward from two ports on the rear deck.
