Pulse generator for ignition advance in internal combustion engine allows regulation of ignition advance without moving first ignition advance point

摘要

Pulse generator includes two windings near stator (s), one used as sensor (C) and one as ignition coil (Ba). Geometric mechanism modifying magnetic coupling comprises margin (X1X2) without modifying of induction flux DELTA o below first ignition point. This allows regulation of ignition advance with resistor (R) of guide system (T) without moving first ignition advance point, placed between X1 and X2.
