Riassunto analitico
The study in the following thesis aims to develop a 0-D model to estimate the instantaneous torque delivered
by an internal combustion engine (ICE). The goal of the model is to accurately estimate instantaneous engine
torque, even at rapid changes in control parameters such as ignition advance and air and fuel masses.
The model has been fitted to experimental data acquired on the engine dyno, where an experimental
campaign was conducted at different engine speed and at different values of air-to-fuel ratio (lambda). At
each value of speed and lambda, a sweep in spark advanced was performed and the cylinder pressure was
measured to calculate the heat release coming from each combustion event.
