GENERAL The common rail system was designed for electronic control of injection quantity, injection tim- ing and injection pressure to obtain optimal operational control. Features • Lower exhaust gas and higher output due to high pressure injection in all usage ranges. • Reduction in noise and exhaust gas due to injection rate control. • Improved performance due to increased flexibility in the injection timing setting. • Independent control of injection pressure in response to engine speed and load.
