Abstract
An ignition timing adjusting apparatus of an internal combustion engine is provided so as to suppress the vibration of the body of a vehicle when it is accelerated. This is achieved by obtaining a first ignition timing compensation magnitude determined on the basis of the revolution speed fluctuation of the internal combustion engine and a second ignition timing compensation magnitude determined on the basis of the engine load condition, and by compensating a basic ignition timing in accordance with the first and second ignition timing compensation magnitude when the vehicle is accelerated.
