Abstract
In order to improve the control characteristics for ignition timing during transient operating conditions including engine startup, during engine transient operating conditions, a controller (1) sets an advance limit ADVLMT restricting the maximum value of the ignition timing advance to a limit ADMLMTS which is a large value when compared to the value for steady-state operating conditions. Furthermore during transient operating conditions, the dwell angle TDWLLB is also increased and the correlation of the ignition timing control with respect to a suitable ignition timing is improved.
