ABSTRACT:
A process for suppressing torque jumps during operation of an internal combustion engine prevents torque jumps when switching pilot injection (pre-injection) on and off in a diesel internal combustion engine by forming a difference between a predetermined total quantity of fuel to be injected and a pilot quantity to be injected by a pilot injector and acting upon the difference with a correction factor that produces torque balancing. A difference quantity which is corrected in this manner represents a main injection quantity.
