Abstract

1,064,731. Ignition systems. JOSEPH LUCAS (INDUSTRIES) Ltd. Nov. 20, 1963 [Dec. 5, 1962], No. 45984/62. Heading F1B. A spark ignition system for an internal combustion engine of the kind in which current flow in a winding 18 controls discharge across a sparking plug of the engine comprises in combination first and second terminals 11, 12 which in use are connected to a D. C. source, a gate controlled switch 21 having its anode and cathode connected across the terminals in series with the winding, a series circuit connected across the terminals, the series circuit including a contact breaker 23 and an inductor 25, means coupling the series circuit to the gate of the gate controlled switch so that in use the gate controlled switch is switched on when the contact breaker closes and is switched off by the energy stored in the inductor when the contact breaker opens, a first capacitor 26a connected across the contact breaker and an additional capacitor 26b connected in the system, the additional capacitor being connected in a position to prevent inadvertent switching on of the gate controlled switch. As a result of sparking between the interrupter contacts after they open. As shown in Fig. 3 a diode 28 is included between the inductor 25 and the point 27 and the capacitor 26bis bridged by a resistor 29. Fig. 4 illustrates two alternative positions for the capacitor 26b. In the full line position the capacitor 26b is connected across the capacitor 26a in series with a resistor 33. In the dotted line position the capacitor 26b is connected between the terminal 11 and the point 27. The coupling to the gate of the switch 21 may be inductive where a low voltage plug is used the plug may be fed from the winding.
