Abstract
A control system for an engine includes a density determination module and a mass air flow (MAF) determination module. The density determination module determines a density of air in an induction system of the engine based on a temperature of the air, a pressure of the air, and a relative humidity of the air. The MAF determination module, based on the determined density of the air, a velocity of the air, and a cross-sectional area of the induction system, determines a MAF through the induction system.
