Abstract
A method for detection of emissions levels during extended engine speed controlled operation is provided. The method includes monitoring mass airflow passing through the engine while operating the engine. The method further includes adjusting mass airflow responsive to engine speed to maintain a desired engine speed. The method further includes shutting down the engine when engine mass airflow becomes higher than a predetermined mass airflow threshold.
