Injection system for diesel engine of car, has hardware channel associated with control law, so that reconfigured control chains are established to allow persistent failure in diagnosis mode to determine that failure occurs from element

摘要

The system has an overall control law (25) operating in a diagnosis mode in which the law associates with individual control laws (21-24) with a hardware channel is formed of drivers (26-29), beam (30) and strands (31-34). The channel initially associated with each individual control law is associated with the control law other than the control law associated with the channel, so that reconfigured control chains are established to allow a persistent failure in the mode to determine that the failure occurs from an element among the individual control law, channel or injectors (11-14).
