•  Common rail diesel fuel injection systems are pressure storage injection systems. This means that the fuel pressure is continuously available on these systems, whereas on traditional systems with distributor injection pumps, the pressure must be newly built up for every injection.

•  Creation of pressure and fuel injection are performed separately on common rail diesel fuel injection systems. Because of this, the build up of injection pressure is largely independent of engine speed and injection quantity.

•  An injection pressure of up to 150 MPa {1530 kgf/cm², 21756 psi} is kept ready in the common rail.
