ABSTRACT:
A device for controlling ignition timing of an engine has a sensor 10 for reading and storing the pressure of a gaseous mixture within each cylinder of a multiple cylinder engine at a predetermined crank angle in the compression cycle; a calculation unit 11 for calculating a charged air quantity or engine load based on the gaseous pressure and the temperature of an intake air; and a control unit 11 responsive to the engine load and the number of engine rotations to determine the ignition timing for the cylinder to be ignited next or the next cycle in its own cylinder.
