Method of ignition advance control for motor vehicle internal combustion engine involves correlating stationary operation and air charge measurement derived ignition advance values

摘要

The method of ignition advance control dependent on applied load for a motor vehicle internal combustion engine involves providing a dynamic precontrol signal from a cylinder air filling target value and a dynamic correction factor. It involves fixing a first advance value with respect to an ignition characteristic linear field for stationary operation and a second value for an air charge measurement and correlating the two advance values. Claims include a motor vehicle internal combustion engine ignition advance calculator using the method.
