Abstract
Official abstract text for this publication.
Methods and systems are provided for adjusting a throttle based on an intake oxygen sensor output. In one example, a method may include adjusting a position of a throttle based on a dilution threshold and a total aircharge dilution level, the total dilution aircharge level based on an output of an intake oxygen sensor. Additionally, spark timing may be adjusted based on the total aircharge dilution level.
First claim
Opening claim text (preview).
The invention claimed is: 1. An engine method, comprising: adjusting a position of a throttle based on a determined dilution threshold and not a total aircharge dilution level when the total aircharge dilution level is greater than the dilution threshold, the total aircharge dilution level based on an output of an intake oxygen sensor; and adjusting the position of the throttle based on the total aircharge dilution level when the total aircharge dilution level is less than the d…
