時期制御装置。 A fuel measuring means measures the remaining amount of fuel to be supplied to the engine, and receives an output signal from this fuel measuring means and compares the remaining fuel amount at the time of starting the engine with the remaining fuel amount when the engine was previously stopped, and calculates the octane value. Octane number determination necessity determining means for determining whether determination is necessary;
It has a predetermined ignition timing control means that receives an output signal from the octane number determination necessity determination means and performs ignition timing control according to a predetermined fuel octane number when octane number determination is not necessary, and when octane number determination is required. An ignition timing control device comprising: octane number determining means for determining an octane number; and ignition timing selection control means for controlling ignition timing in response to an output signal of the octane number determining means.
