Abstract

1293288 Timing ignition FORD MOTOR CO Ltd 25 May 1971 [6 July 1970] 16824/71 Heading F1B A spark timing control system comprises an engine carburetter 10 having an induction passage 18 containing a spark port 28 located above the idle speed position of a throttle valve 26 controlling flow through the passage and subject to the depression in the carburetter as a function of movement of the throttle valve from its idle speed position, an engine distributer having a breaker plate 12 pivotally movable in opposite directions to advance and retard the spark timing, vacuum controlled servo means 14 connected to the breaker plate for moving the same and slow fast flow-rate control means 53 between the spark port and servo means to control the rate of change of application of vacuum from the spark port to the servo means. The control means includes faster flow-rate means 62, 66 operable in response to a change in the depression at the spark port to a lesser depression than at the servo means to quickly equalize the pressure level at the servo means to that at the spark port and slower flow-rate means 76 operable in response to a change in the depression at the spark port to a greater depression than at the servo means to delay the equalization of the pressure level at the servo means to that at the spark port to delay the spark timing change.
