Abstract
A method for controlling a common rail injection system for turbochargeable internal combustion engines, in particular diesel engines, in which in a first steady-state or quasi-steady state load condition of the internal combustion engine, a rail pressure is established as a function of the injection volume in accordance with a first characteristic curve, the rail pressure being established in a second, non-steady-state load condition of the internal combustion engine, in particular at non-steady-state full load, as a function of the injection volume in accordance with a second characteristic curve, the rail pressure in the case of the non-steady-state load condition being elevated in each case with respect to the rail pressure in the presence of the steady-state or quasi-steady-state load condition, with an identical injection volume.
