Electronic ignition signal distributor for automobile engine

摘要

Disclosed is an electronic ignition signal distributor for automobile engine, in which cylinders of the engine are identified using an ignition sequence counter and basing on the reference position signal and crank angle signal. The cylinder identity signal is taken AND with the distributed ignition position signal before being applied to the ignition device, thereby preventing the delivery of an active ignition signal in the event of a malfunctioning of the counter or cylinder identifying circuit, and ultimately preventing an erroneous ignition of irrelevant cylinders caused by a noise or the like.
