Abstract:
A device for determining an ignition angle of an internal combustion engine, comprising:a limiting module configured to limit a setpoint ignition angle to a maximally retarded ignition angle for an operation of the engine, the setpoint ignition angle optimized as a function of operating parameters of the engine; and a control unit containing functions to differentiate between a steady operating state and at least one dynamic operating state, wherein in the steady operating state, the maximally retarded ignition angle assumes a value of a static combustion limit; and wherein for each dynamic operating state, the control unit contains at least one differential ignition angle which, upon occurrence of a respective dynamic operating state, is configured to bring about a shift of the maximally retarded ignition angle to more advanced ignition angles with respect to the static combustion limit.
