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.

Dependent claims

A common rail system for an internal combustion engine, having:

a rail for fuel, and an injector which is connected by a fluid connection via a high-pressure conduit, of the injector configured to inject fuel into a working chamber of the internal combustion engine, wherein the high-pressure conduit has a high-pressure component with an individual reservoir, and
at least one of the high-pressure conduit and of the rail has a pressure measurement device , wherein
the pressure measurement device is coupled to a local logic and storage device of a decentralized local electronic device, the electronic device being configured to locally analyze and store measurement data from the pressure measurement device, and
the pressure measurement device is connected to the central electronic device via a bus, and via the local logic and storage device, and the local logic and storage device is configured, together with the central electronic device to control the common rail system for the internal combustion engine.
