Abstract

An internal combustion engine, especially for a motor vehicle, is described which is provided with a control apparatus. A number of functions can be executed at time intervals and/or in dependence upon the rpm of the engine. Furthermore, a quantity (RA), which defines the utilization of the control apparatus, and a quantity (N), which defines the rpm of the engine, can be determined. The number of executed functions can be reduced by the control apparatus when the quantity (RA), which defines the utilization, is greater than a utilization threshold value (ASW1).
