Abstract

PURPOSE:To stabilize ignition timing in a steady state by determining the ignition timing on the basis of the changing amount of the ignition timing and those of factors indicating a driving state. CONSTITUTION:Outputs of a revolution number detector 1 and sucked-air amount detector 2 are input into a microcomputer 3. When the ratio between two changing amounts, a changing amount of a timing at present to the one in advance by one ignition and that of a sucked amount of air to indicate a driving state at present to the one in advance by one ignition, is greater than a predetermined value, and a changing amount of the number of revolutions at present to the one in advance by one ignition is smaller than a predetermined value, the microcomputer 3 commands an ignition circuit 4 to ignite at the same ignition timing as the one in advance by one ignition.
