Engine torque estimation for DI diesel engines

This paper presents a new approach for internal combustion engine torque estimation from instantaneous crankshaft speed measurement, in presence of unknown load torque. The design of the estimator is based on a detailed crankshaft dynamic equation and on a simple in-cylinder pressure model. Some preliminary validation results are provided, based on a high-resolution thermodynamical engine model. This estimator may be used later for closed-loop engine torque control.
