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.

Method and apparatus for estimating engine operating parameters

Operating an engine includes monitoring engine crank position, a corresponding engine torque, and an engine operating point. A state of an engine control parameter is adjusted in response to a difference between an identified location of peak torque and a preferred location of peak torque.
