Patent DE-2214772-A1 (DE)
Title: Exhaust gas purification system - using valve to bypass activated carbon bed preceding catalytic converter at high temperatures
Inventor: STORP KLAUS DIPL CHEM DR RER N
IPC: F01N13/02
Filed: 1972-03-25
Abstract: The exhaust gases of an internal combustion engine are purified by removing first the nitric oxides in a catalyst. At low temperatures the gases are then passed through an activated carbon bed where the hydrocarbons are absorbed at temperatures of under 200 degrees C. At higher temperatures, desorption takes place and the temperature of the fullowing catalytic converter is quickly raised by the after-combustion of the hydrocarbons. At temperatures of 300-350 degrees C a change-over flap valve bypasses automatically the activated carbon bed and the exhaust gases are passed straight to the catalytic converter. This speeds up to heating up time and prevents the emission of otxic exhaust gases during the starting period without undue increase in consumption of activated carbon.

IPC: F24F9/00
Filed: 1973-11-28
Abstract: A room has an opening to outside. Immediately inside the opening and above it is an air curtain unit containing a fan and discharge nozzles directed outwards at an angle to the vertical. There is a duct in the floor of the room below the air curtain and just inside the opening to outside. The duct is covered by a grating to facilitate the passage of people and vehicles.
