Abstract:
An apparatus for determining the ignition angle for an internal combustion engine with adaptive knocking control, comprising:a non-volatile memory for storing a characteristic diagram and generating a learnt RON level;a first device operatively coupled to the non-volatile memory for receiving a starting value of a RON level and the learnt RON level;a second device operatively coupled to the non-volatile memory and the first device for determining a maximum control range;a third device operatively coupled to the second device for continuously comparing the maximum control range with a control range;a fourth device operatively coupled to the first device for determining a basic retarded-direction adjustment;a fifth device operatively coupled to the fourth device for multiplying a correction factor by the basic retarded-direction adjustment; anda sixth device operatively coupled to the fifth device for determining the correction factor.
