An Air Meter Based Cylinder Air Charge Estimator 1999-01-0856
A manifold filling model is used to derive a real time cylinder air charge estimate for mass air flow rate sensor equipped vehicles. The derivation shows that a simple first order linear difference equation in the discrete cylinder event domain is obtained from a coupled set of nonlinear differential equations.
