    • Capacitor discharge ignition system having a microprocessor disposed thereon to control the ignition timing of the system. The system has a generator coil, a primary coil and a secondary coil on the same leg portion of a ferromagnetic core. An electronic circuit associated with the microprocessor includes a capacitor adapted to be charged by an intermediate pulse generated by the charge coil with the leading and trailing pulses thereof being input to control the operation of the microprocessor. The circuit also includes an SCR having its anode-cathode path connected in circuit with the capacitor and primary coil and its gate connected to an output port of the microprocessor which also includes an input port to power the microprocessor from the charge coil. Another port of the microprocessor is adapted to receive timing reference inputs from the charge coil. The microprocessor is programmed to send a signal to the SCR that causes the capacitor to discharge through the primary and thereby induce an ignition pulse in the secondary. In addition, the microprocessor is programmed to be cut "off" and remain "off" for the duration of the ignition pulse.

    • A primary direct current power source (10) is controlled by a thermostat (8) and a secondary direct current power source (32,34) is independent of the thermostat. A first relay (22) is in circuit with the oil burner motor (4) to energize the same and a second relay (24) is in series with the first and with an alternating voltage source for energizing the ignitor (6) of the furnace. An electronic circuit controls the first relay switch (122) and includes a pair of silicon controlled rectifiers (SCR's) (80,82) connected in series for energizing the first relay. A second electronic circuit includes a pair of inter­connected NPN transistors (102,112) for controlling the operation of the second relay switch (124). The first NPN transistor (112) is conductive when the second relay switch (124) is energized and the second NPN transistor(102) is connected to the first to turn "OFF" the same in response to flame being sensed in the furnace. A flame sensing element (30) in the furnace is associated with a control relay (128) for controlling a pair of relay switches, one of which (28) is in series with the SCR's and the other (38) is adapted to energize a redundant pair of time-delay circuits. Each time-delay circuit includes a capacitor (98) and a programmable unijunction transistor (PUT) (94) programmed to breakover at a voltage which is a function of a first predetermined time for charg­ing a capacitor and a resistance in the cathode circuit of each PUT which provides for a second predetermined time for the discharge of the capacitor voltage to hold the second relay (24) "OPEN" by conduction through the second NPN transistor (102). Another electronic circuit includes an NPN transistor (72) and PNP transistor (74) connected to energize the first relay switch (122).
