Abstract

Exemplary illustrations are provided of a common rail system for an internal combustion engine, having a rail for fuel and an injector for the purpose of injecting the fuel into a working space of the internal combustion engine, said injector having a fluid connection to said rail via a high-pressure conduit. The high-pressure conduit may have a high-pressure component with an individual reservoir, and the high-pressure conduit and/or the rail may have a pressure measurement device. The pressure measurement device may be coupled to a local logic and storage device of a decentralized, local electronic device which is designed for the purpose of locally analyzing and storing measurement data of the pressure measurement device, e.g., injector data and/or rail data, and the pressure measurement device is connected to the central electronic device via a bus, with the local logic and storage device connected between the same.
