Method for estimating volumetric efficiency in powertrain
A method for estimating the volumetric efficiency in an internal combustion engine in real time includes the following steps: (a) monitoring an oxygen percentage of gases in the intake manifold using an oxygen sensor coupled to an intake manifold; and (b) determining, via a control module, a volumetric efficiency of the internal combustion engine in real time based, at least in part, on the oxygen percentage of the gases in the intake manifold.
