Abstract
Official abstract text for this publication.
Methods and systems are provided for cleaning out condensate stored at a charge air cooler. In response to increased condensate accumulation at a charge air cooler, airflow through the engine is increased to purge the condensate while an engine actuator is adjusted to maintain engine torque. Combustion stability issues of engine cylinders are addressed by adjusting fueling of each cylinder individually during condensate ingestion.
First claim
Opening claim text (preview).
The invention claimed is: 1. An engine method, comprising: purging condensate from a charge air cooler while temporarily shifting cylinder combustion to a lean stratified mode, a degree of enleanment based on an amount of condensate at the charge air cooler and a cylinder firing order during the purging. 2. The method of claim 1 , wherein temporarily shifting cylinder combustion to the lean stratified mode includes shifting combustion in a first cylinder hav…
