Abstract
A method for operating an internal combustion engine includes monitoring signal output from a high-resolution torque sensor configured to monitor engine torque during ongoing operation, monitoring states of engine operating and control parameters associated with engine input parameters, and estimating a mass air charge for each cylinder event corresponding to the signal output from the high-resolution torque sensor and the states of engine operating and control parameters associated with the engine input parameters.
