Abstract (en)
[origin: EP1072780A2] The method involves setting the rail pressure as a function of the injection quantity according to a first characteristic in a stationary or quasi-stationary load state. In a second, non-stationary engine load state, esp. for non-stationary full load, the rail pressure is set as a function of injection quantity according to a second characteristic and is increased wrt. the pressure for a stationary or quasi-stationary state.
