Date Feb. 7, 1991.A method for carrying out sequential injection processes when predetermined injection angles are reached in which crankshaft-angle increment signals are generated and these increment signals are counted in relation to a reference signal. With the aid of these increment signals, it is determined whether an injection angle set as an increment value has been reached. As soon as this is determined, the injection process assigned to this increment value is carried out, i.e., injection is begun or ended. Using this method, it is possible to set injection start angles and/or injection end angles accurately, it is possible to set the angular position of injection processes in relation to intake processes more accurately than hitherto, and it is possible, with great reliability, to avoid the occurrence of overenrichment and leaning due to an injection process being begun during a still continuing preceding intake stroke or being continued beyond a decisive intake stroke. |
