Cover Story: Common rail systems are a key component of modern diesel engines as they highly increase their performance. Nevertheless, there could be critical damages or failures related to aging or out-of-spec operating conditions. Suitable data-driven methods are adopted in our work to develop an automatic procedure to investigate typical faults. In particular, the pressure control loop within the engine control unit is analyzed and the system dynamics are described using a Hammerstein model composed of a nonlinear block for the control valve and an extended linear model for the process, which also accounts for disturbances. Three sources of oscillations can be successfully detected and quantified: valve stiction, aggressive controller tuning, and external disturbance. View this paper
