Gasoline Engine Ignition Control

Present day ignition control systems may be enhanced by substituting solid- state devices, to give longer life and better control of firing spark plugs of a gasoline engine.

Such solid-state devices may be made up of magnetoresistors, as illustrated above. Referring to Fig. 1, six magnetoresistors 10-20 are positioned on a rotating disc 22 and positioned to cut through a field created by a stationary permanent magnet 26. Alternatively, it may be seen that the same result may be achieved with the permanent magnet 26 rotating, and the magneto resistors 10- 20 being fixed and stationary.

As another approach to achieve the desired results, six permanent magnets 30-40 may be positioned on a rotating disc 42, as illustrated in Fig. 2, with a magnetoresistor 44 being stationary. Again, this could also be reversed, in that the resistor 44 could be positioned on the disc 42 while the magnets 30-40 could be stationary.
