Abstract
Future internal combustion engine technologies require an accurate combustion monitoring and control. This can be performed through high frequency recordings and processing of combustion related variables such as cylinder pressure or knock signals. This paper presents a flexible rapid prototyping system based on xPC target which can be used for multi sensor recordings and for signal processing algorithm developments. After a description of the platform hardware and software, an example of combustion analysis based on cylinder pressure and accelerometer signals is given. The paper ends with a comparison of direct and indirect combustion parameters computation in real time for closed loop combustion control purpose.
