Abstract

Methods and systems are provided for an engine. A condition of the engine may be diagnosed based on a combustion torque profile of the engine estimated using signals from a generator operationally connected to the engine and/or other signals associated with the engine. Different types of degradation may be distinguished based on discerning characteristics within the estimated combustion torque profile data. Thus, a degraded engine component may be identified in a manner that reduces service induced delay.
