Catalyst Efficiency Monitor

The Catalyst Efficiency Monitor uses an oxygen sensor before and after the catalyst to infer Hydrocarbon
conversion efficiency, based on oxygen storage capac ity. Under normal closed-loop fuel conditions, high
efficiency catalysts have significant oxygen storage, which makes the switching frequency of the rear
HO2S quite slow compared with the switching freque ncy of the front HO2S. As catalyst efficiency
deteriorates, its ability to store oxygen declines and the post-catalyst HO2S signal begins to switch more
rapidly, approaching the switching frequency of the pre-catalyst HO2S.

In order to assess catalyst oxygen storage, the monitor compares front and rear HO2S signals during
closed-loop fuel conditions after the engine is warm ed-up and inferred catalyst temperature is within
limits. Front H02S signals are accumulated in up to ni ne different air mass regions or cells although 3 air
mass regions is typical. Rear H02S signals are counted in a single cell for all air mass regions. Currently
there are two algorithms that can be used to compare the front and rear HO2S signals:

1. Switch Ratio method;
The Switch Ratio method compares the 'switch frequencies' of the front and rear HO2S sensors. A
'switch' is counted every time the HO2S voltage output passes through a defined threshold (0.45 V).
The catalyst condition is diagnosed by dividing the number of rear H02S switches by the number of
front HO2S switches.

2. Index Ratio method.
The Index Ratio method calculates and compares the length of the front and rear HO2S signals. The
catalyst condition is diagnosed by dividing the length of the rear HO2S signal by the length of the front
HO2S signal.

A Switch / Index Ratio near 0.0 indicates high oxygen storage capacity, hence high HC efficiency. A
Switch / Index Ratio near 1.0 indicates low oxygen storage capacity, hence low efficiency. To improve the
robustness of the monitor, the Switch / Index Ratio is calculated using an Exponentially Weighted Moving
Average (EWMA) algorithm. If the Switch / Index Ratio exceeds the threshold, the catalyst is considered
failed.
