Abstract:
A method for controlling an internal combustion engine in which a motor controller determines an injection point and injection period for internal combustion engine cylinders in crank angle synchronous transmission cycles, as a function of a load acting on the internal combustion engine, and transmits the determined injection point and injection period to actuators that are assigned to the cylinders, as a control data set for execution of an injection, wherein:for every transmission cycle in the control data set, said controller transmits control information for injection of a cylinder currently to be addressed, and reserve information for injection of a cylinder to be addressed in the following transmission cycle; and at least said reserve information is saved for at least one transmission cycle; in a stable running mode, control information from a current transmission cycle is used for fuel injection into the cylinder currently to be addressed, and one of current control information and reserve information from the current transmission cycle overwrites reserve information from a previous transmission cycle; and upon the occurrence of a load increase that increases injection periods in such a significant way that, in terms of time, injection start in the cylinder currently to be addressed would come before start of a current transmission cycle, reserve information from a next preceding transmission cycle is used for injection of the current cylinder.
