In a future ‘hybrid mode’ SI/HCCI engine transition between these modes, over the operating map, will play a crucial role. The
engine management system must provide a fast and smooth transition between these two modes, hence a new combustion
feedback based control system is needed. The aim of this paper is to investigate the use of an ion-current sensor in SI/HCCI
engine for direct combustion feedback control. The experimental results obtained, at different speed and loads, show that the
estimation of cylinder pressure, through the ion signal, can be performed with high accuracy, and that ion-current has the
potential to be a cost effective solution for direct combustion control.
