The invention is a further development of an earlier arrangement of r.p.m. limitation (SE-P-452 355). The advantage of this invention is that the adjustment of pulse times is eliminated. The arrangement can be manufactured without cost demanding adjustment as the circuit is crystal-controlled which involves a great accuracy. As the r.p.m. increases, the pulse t2 of the second flip-flop comes closer to the next ignition pulse of the ignition system and, at the limitation speed, t2 begins to overlap the ignition pulse. The ignition time T is delayed and an ignition delay takes place with a subsequent limitation of the r.p.m. |
