Claim:
1. A method for open-loop and closed-loop control of a V-type internal combustion engine with an independent A-side common rail system having only one A-side common rail and A-side injectors in fluid communication with the only one A-side common rail and an independent B-side common rail system having only one B-side common rail and B-side injectors in fluid communication with the only one B-side common rail, the A-side injectors being separate from the B-side injectors, the method comprising the steps of: automatically controlling speed of the internal combustion engine in a closed-loop speed control system; and limiting a set torque, as a correcting variable of a speed controller, during a start-up process to a starting torque to produce a zero set injection quantity so that injection to both sides remains blocked as long as the A-side actual pressure and the B-side actual rail pressure are less than a starting rail pressure, the method further including enabling a positive set injection quantity when a verified engine speed is present, both an A-side rail pressure sensor and a B-side rail pressure sensor are operating correctly, and both the A-side actual rail pressure and the B-side actual rail pressure exceed the starting rail pressure.
