摘要： A high-frequency continuous-wave ignition system for internal combustion engines. It employs a unitary magnetic circuit in a square-wave oscillator. Starting and stopping the oscillator is controlled by a winding coupled to the magnetic circuit. A circuit including this control winding has a full-wave AC shortcircuit connection for stopping the oscillator between sparking intervals. However, a predetermined half-wave path in the short circuit has a greater impedance than the other half-wave path. This acts so that the magnetic circuit is always set in a given state as the oscillator is stopped. As a result it ensures instant starting of the oscillator at the beginning of each sparking interval.

摘要： The invention relates to an ignition system for supplying energy to a spark device. The system includes a first capacitor which can be charged from a source of DC supply, a device which breaks down when the voltage across the capacitor attains a predetermined value thereby to allow the capacitor to discharge through the spark device and a further capacitor which is connected in parallel with the capacitor and which can be charged from a separate source of supply when a higher energy is required, there being provided a unidirectional current flow device in series with the two capacitors.

摘要： Jet engine fuel igniters are excited with a current waveform which maintains an intermediate current value until a discharge has separated from the igniter surface. The current then rises to a higher level to provide sufficient energy for ignition of an air-fuel mixture. Ignition reliability is thus increased and the effects of erosion on the igniter surface are decreased.

摘要： A capacitor discharge ignition system which includes a storage capacitor, a charging circuit for charging the capacitor, a switch effectively directly connected across the output of the charging circuit and adapted to be actuated in timed relation with respect to an engine, wherein the charging circuit comprises a converter which stalls on actuation of the switch means which is connected to provide a low impedance short across the output of the converter to reset the converter and switch means in timed relation as a function of the engine speed. The switch includes a trigger circuit and a feedback circuit is provided to feed back a portion of the energy stored in the storage capacitor to effectively completely discharge the trigger circuit of the switch when actuated. There may further be provided means for supplying a reverse gate voltage to the switch means to prevent spurious signals from actuating same.

摘要： A capacitor discharge type ignition system is arranged to deliver pulses of energy to the distributor of an engine, thereby to generate ignition sparks. A control circuit is provided for controlling the duration of the energy pulses, and hence the duration of ignition sparks, as a function of selected operating conditions of the ignition system and its associated engine, such as, supply voltage level, operating temperature and engine speed.

摘要： A pulse transformer connects a capacitor to an ignition means. A secondary coil housing is a tubular shaped member molded about a core leg carrying a flat wound primary coil. An axially extended coaxial recess receives a multi-turn single layer secondary coil wound on a support tube. The recess is filled with a suitable potting material and a U-shaped core assembly is secured to the center core leg to define a closed rectangular path. A high voltage connector is connected to the innermost turn of the secondary coil with a minimum spacing therebetween.
