An air control method for an internal combustion engine having air assist injectors and an electronically controlled throttle maximizes airflow through the injectors while maintaining a range of authority for the electronically controlled throttle. This method maximizes the benefits of fuel atomization while maintaining a desired engine speed in the presence of disturbances.

[ What is claimed is:] [1.] An air control method for an internal combustion engine having a combined airflow into the engine including a first airflow into the engine via a first airflow control valve and a second airflow into the engine via a second airflow control valve and an air assist injector

[ What is claimed is:] [1.] An air control method for an internal combustion engine having a combined airflow into the engine including a first airflow into the engine via a first airflow control valve and a second airflow into the engine via a second airflow control valve and an air assist injector, the method comprising:generating a predetermined airflow threshold;adjusting the first control valve to control the combined airflow to a desired combined airflow; andadjusting the second control valve to control the second airflow to be less than said predetermined airflow threshold to prevent the first control valve from closing less than a preselected amount.
