Due to the recent anti-pollution policies, the performance increase in Spark Ignition (SI) engines is currently under the focus of automotive manufacturers. This trend drives control systems designers to investigate accurate solutions and build more sophisticated algorithms to increase the efficiency of this kind of engines.The development of a control strategy is composed of several phases and steps, and the first part of such process is typically spent in defining and investigating the logic of the strategy. During this phase it is often useful to have a light engine simulator, which allows to have robust synthetic combustion data with a low calibration and computational effort.In the first part of this paper, a description of the control-oriented ANalytical Engine SIMulator (ANESIM) is carried out. The latest results about the zero-dimensional knock model presented in a previous paper and some interesting analytical equations which define the main mean-combustion indexes trends (for example maximum in-cylinder pressure, or Pmax, 50 percent fuel mass fraction burned angle, or MFB50, Indicated Mean Effective Pressure, or IMEP) as functions of engine speed…
