Abstract:
PCT No. PCT/DE89/00135 Sec. 371 Date Oct. 2, 1990 Sec. 102(e) Date Oct. 2, 1990 PCT Filed Mar. 4, 1989 PCT Pub. No. WO89/09334 PCT Pub. Date Oct. 5, 1989.A method for learning control and precontrol for adjusting the lambda value for the air/fuel mixture to be metered to an internal combustion engine 11 compares a large comparison value with a small comparison value with the large comparison value being formed by averaging of adaptation factors for large precontrol values and the small comparison value being formed by averaging of adaptation factors for small precontrol values. Whenever the large comparison value is smaller than the small comparison value, a global summand is incremented by a correction value, otherwise it is decremented. An apparatus operating according to this method has the advantage that disturbing influences which act additively on the injection time are compensated with great accuracy.
