Provning av katalysator i en förbränningsmotors avgassystem

摘要

Method for the testing of catalysers of combustion engines, where a gas sensor is placed in the exhausts after the catalyser which is sensitive to some substances normally burnable for the catalyser, for instance a thin oil. While the engine runs, momentarily a suitable amount of this substance is fed to the inlet of the engine, so that the gas sensor indicates the presence of the substance in the exhaust gases and so indicates the correct functioning of the catalyser system.
