Abstract

1,226,113. Ignition systems. PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd. April 23, 1968 [April 26, 1967], No.19153/68. Heading F1B. [Also in Division H3] A train of high voltage pulses is supplied to a sparking plug at 5, each time a switch 25 is opened, by a secondary winding 4 of a transformer 3 whose primary 2 is in series with a capacitor 1 which is repeatedly charged (by diodes 16, 17), and discharged by an SCR 18; the circuit controlling the SCR 18 being responsive to a control signal (the opening of the switch 25) and to a voltage dependent upon the capacitor voltage at any time (and derived via resistor 21). The switch 25 is controlled by an engine, whose spark plugs are fired by the secondary 4, and provided the switch is open, a sufficiently positive potential on the capacitor 1 causes transistor 19 to turn off, transistor 26 to turn on, and the SCR 18 therefore to conduct. An oscillator comprising a transistor 7 and a transformer 9, 10, 11 supplies a voltage doubler 15, 16, 17 to charge the capacitor 1. Successive charging and discharging of C1 occurs until the switch 25 closes. Each pulse causes the capacitor 1 and primary 2 of transformer 3 to resonate, the SCR 18 conducting alternate half cycles of the damped oscillation, and diodes 16, 17 the other half cycles, so that if the recovery time of SCR 18 is greater than a half cycle at the natural frequency of L2C1, each h.v. pulse will cause a series of damped oscillations. The switch 25 may be replaced by an engine-driven magnet co-operating with either a coil, or a Hall effect device. In a first modification Fig.2, (not shown), a two-transistor oscillator is used (7, 7<SP>1</SP>) and is connected to a bridge rectifier 15<SP>1</SP>; and the transistors 19, 26 are arranged as a complementary pair with a time delay circuit (32-37) in the base circuit of one transistor 19, to ensure continuing conduction of the SCR 18 during the damped oscillations of the resonant circuit (1, 2 etc). In a second modification Fig.3 (not shown) the complementary pair (19, 26<SP>1</SP>) is rearranged and the switch 25 is replaced by a photo-resistor responsive to light from a lamp (40) passing through an apertured disc 43, also Fig.4, (not shown) driven by the engine. In a further modification Fig. 5, (not shown), the photo-resistor is replaced by a photo-transistor (38<SP>1</SP>) which, with several additional transistors which increase amplification and sensitivity of the device, are built as an integrated circuit (50). The lamp intensity and the sensitivity of the photo-resistor or photo-transistor are variable in accordance with engine parameters for automatic ignition control.
