ABSTRACT:
A system for predicting cylinder air charge for a variable displacement internal combustion engine operating in a transition from a first number of activated cylinders to a second number of activated cylinders includes a throttle sensing system for determining the effective flow area of the air intake passage of the engine and for generating a signal corresponding to the area, an engine speed sensor for determining the speed of the engine and for generating a signal corresponding to the speed, an airflow sensor for determining the instantaneous mass airflow into the engine and for generating a signal corresponding to the airflow, and a controller for receiving the speed, flow area, and mass airflow signals and for calculating the mass of air admitted to each engine cylinder during its intake stroke, based upon the values of the signals.
