METHOD FOR MONITORING THE FUNCTION OF CATALYSTS IN INTERNAL COMBUSTION ENGINES |
摘要 |
A process is suggested for checking the catalyst performance in internal-combustion engines, in which by means of detected operating parameters of the internal-combustion engine similar operating conditions are determined. It is suggested to compute from a defined number of measured exhaust gas values during a similar operating condition a statistically backed average exhaust gas value and compare it with a permissible exhaust gas value stored for this operating condition, so that a defective catalyst is recognized in the event of a deviation of the actually determined exhaust gas value from the permissible exhaust gas value. |
