PCT No. PCT/DE94/00981 Sec. 371 Date May 11, 1995 Sec. 102(e) Date May 11, 1995 PCT Filed Aug. 25, 1994 PCT Pub. No. WO95/07501 PCT Pub. Date Mar. 16, 1995An electronic control device for controlling a fuel injection starting time and an injection duration in an internal combustion engine has an event device (E) which generates an event signal (ES) as a function of a prescribed occurrence of an event and a device for controlling or setting the injection duration including a first register (R1), a loading device (L) and a counter (Z). The event device (E) includes a second register (R2), a clock device (TE) and a comparator (K) which compares a stored register value in the second register (R2) with clock data from the clock device (TE) to produce a comparator signal for generation of the event signal (ES) when the stored register value corresponds to the clock data from the clock device. A variable register value for the injection duration is stored in the first register (R1) as a starting value of the counter when the event signal (ES) is input into the loading device (L) and the counter and the injection process are started when the variable register value is input into the counter (Z) and stopped when the counter reaches a predetermined count.
