ABSTRACT:
A method of regulating operation of an internal combustion engine includes monitoring a manifold absolute pressure (MAP) of the engine, determining an engine torque based on the MAP, estimating an air per cylinder (APC) based on the torque, determining a volumetric efficiency of the engine based on the APC and regulating operation of the engine based on the volumetric efficiency.
