Abstract
1377182 Automatic control of speed ASSOCIATED ENG Ltd 25 Jan 1972 [1 Feb 1971] 3641/71 Heading G3R [Also in Division F2] Electrical pulses from an engine-driven contact breaker 10 of a primary ignition circuit 12, after processing in a pulse shaper PS monostable vibrator M, and amplifier AM, produce at C pulses of uniform height and width, spaced by distances which decrease with speed increase, which pulses Fig. 2 (C), (not shown) are averaged at 57 to produce a voltage proportional to engine speed, which is fed to electronic control systems respectively controlling drive-ratio of an automatic transmission 58 and engine governor 59. The circuit further includes first and second binary dividers BD, BD2, producing two outputs 51, 52 in which the pulses are of opposite phase and of a width Figs. 2 (e) (f) (not shown) equal to two pulses and two zeros of the C pulse, their purpose being to control unspecified equipment associated with the engine.
