PURPOSE:To make an engine so as not to be stalled in time of ungearing from a high engine speed as well as in time of load such as clutch meeting or the like being added, by compensating a response lag attributable to the response lag of a cylinder suction air quantity at variations in the engine speed. CONSTITUTION:An ignition timing controller for an internal-combustion engine is provided with an ignition timing calculating device C calculating the ignition timing commensurate to an engine operating state and an actual torque calculating device A calculating an acural torque equivalent value equal to torque, which an engine actually produces in conformity with its speed, on the basis of a reciprocal number value of the engine speed and an ideal torque calculating device B calculating an ideal torque equavalent value equal to ideal torque, which the engine produces in conformity with its speed. In addition, it is provided with an ignition timing compensating device D compensating the ignition timing calculated by the ignition timing calculating device C on the basis of both numerations of the actual torque calculating device A and the ideal torque calculating device B. |
