Abstract:
A method of operating an internal combustion engine, especially of a motor vehicle, by means of a control apparatus wherein a number of functions are executed at time intervals and/or in dependence upon the rpm of the engine and wherein a quantity (RA) which defines the utilization of the control apparatus, and a quantity (N), which defines the rpm of the engine, are determined, the method comprising the steps of:increasing the time interval (A) of the execution of the functions when the quantity (N), which defines the rpm, is greater than an rpm threshold value (DSW1) or when the quantity (RA), which defines the utilization, is greater than the utilization threshold value (ASW1); and, also reducing the number of executed functions when the quantity (RA), which defines the utilization, is greater than a utilization threshold value ASW1.
