This paper presents a zero dimensional thermodynamic model that predicts the pressure behavior in the combustion chamber of a small compression ignition monocylinder engine. In fact this is a virtual pressure sensor, very simple to be implemented on microcontroller. It cooperates with the electronic control unit to perform the engine management. The aim of this innovative system, just patented, is to act on the control injection strategy improving engine performance, reducing consumption, emissions and acoustic noise.
