ABSTRACT:
An internal combustion engine system includes a plurality of pneumatic elements including pneumatic resistances, pneumatic capacitances, and pneumatic sources. A pneumatic state model determines a pressure rate of change and pressure for certain areas of the internal combustion engine system designated as pneumatic volume nodes. Intake port flow is determined from pressures at the intake and exhaust manifolds, engine RPM and density correction factors. Intake port flow in a variable valve timing engine system further includes a phase deviation of the valve timing in the determination thereof.
