Title: Correlation function circuit for spark ignition engines - determines ignition point from rotational speed and angular displacement variables
Inventor: SEITE GUY
IPC: F02P5/15
Filed: 1975-06-26
Abstract: The correlation function circuit is useful for determining ignition timing in spark ignition engines, whereby the function z = f (y) can be determined from x, the angular displacement and y, the rotation speed. These variables can be provided by a special coding disc attached to the motor crankshaft which converts them to digital form. One of the outputs from the digitiser is connected to a bistable (25), the other forms one input of an AND-gate (28). The Q output of the flip-flop drives a monostable (26) and the inverted Q output is connected to an OR-gate (27) together with the output from the monostable. The AND-gate output drives a counter (29) whose output is in parallel with a comparator (31). One input to the comparator is fed with the number (K + 1) - related to the number of slits or marks on the disc - and when parity with the counter is detected, the output signal is the required ignition point.
