Abstract:
An apparatus for fresh airflow determination includes an operating conditions module that interprets a MAF value, a current operating condition and a charge flow value. The apparatus further includes a volume estimation module that determines an apparent plumbing volume of an air intake assembly in response to the MAF value, the current operating condition and the charge flow value. The apparatus further includes a volume reporting module that provides the apparent plumbing volume.
