INDUCTIVE IGNITION SYSTEM FOR INTERNAL COMBUSTION ENGINES WITH ELECTRONICALLY CONTROLLED IGNITION ADVANCE.

摘要

AN INDUCTIVE IGNITION SYSTEM IS PRESENTED FOR INTERNAL COMBUSTION MOTORS WITH ELECTRONICALLY CONTROLLED SPARK ADVANCE. A VOLTAGE GENERATOR (10, 12) UNDERSTANDS THE PRIMARY WINDING (L1) OF AN IGNITION COIL (L1, L2) EACH SIDE OF WHICH IS GROUNDED BY AN ELECTRONIC CURRENT CONTROL SWITCH (MOS1, MOS2) WHOSE STATE CONDUCTIVE IS INHIBITED BY ELECTRIC SIGNALS SUPPLIED TO A DOOR (G) OF THE RESPECTIVE CONTROL SWITCH (MOS1, MOS2) THROUGH A MAGNETIC CAPTURE DEVICE (P1, P2); THE TWO COLLECTION DEVICES HAVE A DIFFERENT NUMBER OF TURNS AND ARE ANGULARLY SEPARATED BETWEEN IN THE MAGNETIC CIRCUIT OF THE VOLTAGE GENERATOR (10, 12), TO TRIP THE CONTROL SWITCHES TO GENERATE SPARKS TO DIFFERENT MOTOR SPEED TIMES. AN INHIBITION CIRCUIT IS SUPPLIED (23) TO MAINTAIN THE INHIBITED STATE OF THE TWO CONTROL SWITCHES (MOS1, MOS2) ALLOWING THE SPARK TO REMAIN ALL THE TIME DURING WHICH THE IGNITION COIL (L1, T2) GENERATES . THE SYSTEM INCLUDES A REVOLUTION LIMITING CIRCUIT (T1, T2) TO LIMIT THE MAXIMUM NUMBER OF ENGINE REVOLUTIONS AND MEANS (DZ3, RG''K) TO ELIMINATE NEGATIVE INFLUENCES FROM THE MAGNETIC VOLTAGE GENERATOR SYSTEM (10, 12) THE IGNITION CIRCUIT.
