A potentially useful method of reducing pollutants in automobile exhaust gas and reducing fuel consumption is the optimum control method for ignition timing of the mixture. Optimum ignition timing varies with the state of engine operation. Moreover, it is a complex function involving parameters of engine operating state. Ignition timing usually expressed as the measure of angular displacement of the engine shaft with varying rotational speed, so that ists control must depend on continuous phase control is proposed. A special feature of this method is that the phase angle between signals for each reference angle input intermittently can be determined in terms of linear functions of repetition frequency of the signals. The principle of phase control by dual-slope integration and an ignition timing controller applying this principle are described.
