Abstract (en)
[origin: US2008312807A1] A process for automatically controlling the rail pressure (pCR) in an internal combustion engine with a common-rail system during the starting operation, the process including: calculating control deviation from a nominal rail pressure and an actual rail pressure; calculating, in a pressure controller, a correcting variable for actuating a suction throttle on the basis of the control deviation; and the suction throttle determining the required quantity of fuel. After the engine has been started, an adaptation process is activated upon detection of a negative control deviation of the rail pressure (pCR) followed by a positive control deviation, as a result of which the correcting variable is changed temporarily in such way as to increase the amount of fuel being delivered.
