ABSTRACT:
For controlling and regulating the startup operation of an internal combustion engine (1) a method is proposed in which a rail pressure is compared with a limit value on activation of the startup operation. Depending on this comparison, a first or second mode is set, whereby the rail pressure (pCR) for the startup operation is controlled in the first mode and is regulated in the second mode. It is provided according to this invention that after the initial setting of the second mode, that mode is retained for the remaining startup operation. This achieves the advantage that high-pressure fluctuations due to alternating modes are effectively prevented.
