摘要
An air flow state determining system that determines a mass air flow into a cylinder of an engine having a cam phaser includes a first module that determines whether an air flow state is one of steady-state and transient based on a cam phaser position. A second module determines the mass air flow using one of a mass air flow sensor signal and a speed density relationship based on whether the mass air flow state is one of steady-state and transient.
