摘要： An ignition coil includes a housing which contains a central core portion, an inner spool having a first winding, and an outer spool having a second winding. The inner spool extends outward of the central core portion. The outer spool extends outward of the inner spool. A locating member includes a locating rib adjacent to an upper portion of the central core portion. The locating rib is in a gap between the inner spool and the central core portion, and locates the inner spool and the central core portion relative to each other. Insulating resin injected into the housing provides insulation among parts in the housing. At least one of the inner spool and the locating member has a void-escape passage which connects the gap and an outside of the inner spool with each other, and which allows a void to escape from the injected insulating resin in the gap.

摘要： An ignition system of the type incorporating, instead of the usual distributor, high-voltage rectifier diodes connected between the secondary winding of an ignition coil and respective spark plugs. In response to voltages developed in the secondary winding in its opposite directions the diodes function to cause discharges at the spark plugs in the firing order of the engine. Each diode is composed of a multiplicity of laminated silicon rectifier diode chips each having a reverse breakdown voltage in the range of 400-850 volts. The reverse breakdown voltage of each diode is 1.1 to 1.8 times the maximum discharge voltage of the spark plugs. Thus constructed, the diodes can well withstand overvoltages that may develop in the secondary circuit of the ignition system.

摘要： A contactless ignition system for internal combustion engines of the type including an ignition coil with two primary windings whose primary currents are alternately switched on and off by two power transistors, further includes two Zener diodes each having a breakdown voltage of 300 to 400 volts and connected in series with one of the power transistors and one of the ignition coil primary windings to function as a reverse current blocking diode. By virtue of two series circuits each including the Zener diode, a diode connected in inverse parallel with one of the power transistors and the primary winding, each of the Zener diodes serves both the reverse current blocking function and the overvoltage protection function. The Zener diodes may be replaced with diodes of the avalance type.
