Abstract

1465670 Ignition systems; limiting engine speed LUCAS ELECTRICAL Ltd 25 Feb 1974 [22 March 1973] 13782/73 Heading F1B A speed limiting system for a Wankel engine having first and second ignition coils controlled by first and second engine driven switches 55, 55a respectively and producing sparks in leading and trailing spark-plugs 59, 59a includes timing means operation of which is initiated by opening of the first engine driven switch and a thyristor 89 which when energized prevents either coil from producing a spark, the timing means serving to energize the thyristor so as to prevent production of sparks above a predetermined engine speed. As shown the thyristor is connected in series with first and second diodes 41, 42 respectively across the primary windings 54, 54a of the first and second coils. One or more of the resistors 75, 81 or 86 may be variable so that delay periods determined by them can be set to suit different requirements.
