Title: Magnetic spark generator for I.C. eninge - two stroke ignition system includes a rectifier and thyristor switch
Inventor: HAUBNER GEORG
IPC: F02P1/08
Filed: 1973-09-08
Abstract: A magnetic spark generator for a single cylinder two stroke engine has a magnet with poles embedded in the rim of a flywheel. Rotation of the flywheel is sensed by an induced voltage produced in a coil wound around the central leg of an "E" shaped core directed towards the flywheel rim. The potential output from the coil is fed through a rectifier so that its time dependent shape is a large central protrusion with a smaller protrusion on either side of the central protrusion. Both the first small protrusion and the larger protrusion are used to sequentially charge a capacitor which is arranged via a thyristor switch to discharge through the primary winding of the spark coil when the charge reaches a predetermined value set by a Zener diode. The speed dependent size of the first protrusion controls the time taken to charge the capacitor and thereby serves as an advance mechanism for the engine.
