ABSTRACT:
A system for controlling the ignition timing of an internal combustion engine comprises an anti-knock control device (7), which includes an evaluating circuit (8) and a control circuit (9). If rapid acceleration occurs the anti-knock control is automatically varied to provide a less pronounced effect than during steady-state operation. In one embodiment the knocking control is by-passed (arrow 12) or switched off, while another embodiment, parameters of the knocking control are varied and made less sensitive, i.e. towards greater knock frequency, whereby the knocking control has a less active effect.
