Motor exhaust catalyst test

摘要

The appts. to determine the deterioration in a catalyst for a combustion engine exhaust has a control to register whether the catalyst body is at a given temp. or not based on a counter for the warming-up action. The warming-up counter gives a count, at a suitable loading of the motor, to show when the catalyst body reaches the required temp.. The control determines from the warming-up behaviour of the catalyst body whether the conditions of deterioration are present or not.
