摘要： An electronic ignition circuit for an internal combustion engine produces an plasma arc across the spark gap of an ignition device. An a.c. circuit is formed of a push-pull inverter (30, 32) a center tap primary step up transformer (28) with feedback coil (44). A capacitor network (72, 74, 76, 78) passes pure a.c. to the primary of an ignition coil (95), so that the wave fed to the ignition device is free of any d.c. component. An impedance (102) connects to the breaker points or equivalent timing device to time the arcing so that an arcing a.c. voltage (106, 108) appears when the points are open, and a low voltage wave (110, 112) appears when the points are closed.

摘要： A pulse generating circuit for a plasma ignition system includes a thyristor (32) connected between a supply terminal (21a) and earth. A primary winding (Wp) of a transformer (TR) and a first capacitor (C I ) are connected across the thyristor (32). The supply terminal (21a) is also connected through a secondary winding (W.) and a diode (D) to an output terminal (21c). A saturable core inductor (L) and a second capacitor (C 2 ) are connected in series across the output terminal (21c) and earth. A plasma plug (15) is also connected across the output terminal and earth. In operation, the first and second capacitors are charged and the thyristor (32) is fired. A high voltage pulse is applied by the secondary winding (W 2 ) to the plasma plug (15) causing electric breakdown. The second capacitor (C 2 ) then discharges through the inductor (L) and the plasma plug (15). Four alternative circuits are also described.

摘要： Système d'allumage à décharge capacitive à plasma pulsé utilisant une nouvelle bobine d'allumage à très haut rendement (3) avec une sortie de haute tension et de courant intense optimisés. La bobine d'allumage (3) est utilisée de préférence en combinaison avec une boîte d'allumage à impulsions multiples de cadence rapide à haut rendement permettant d'obtenir des sites d'allumage à plasma à cadence rapide. La bobine (3) présente un faible rapport de spires d'enroulement d'environ 40, de faibles inductances primaire et secondaire (1, 2) et résistances (11, 12), une faible perte dans son noyau (3a), une faible capacitance secondaire (5) et est utilisée en combinaison avec un condensateur (4) dont la capacité varie entre 1 et 20 microfarads. Le système utilise un doublage de la tension au niveau de l'éclateur (9) avec une cadence très élevée de montée de tension et de valeurs de crête de tension par une combinaison de configurations de bobine/condensateur permettant d'utiliser un éclateur relativement large (9) et d'obtenir un courant très intense.

摘要： A plasma jet ignitor apparatus for generating plasma from a plasma medium such as hydrogen and for discharging the plasma as a jet into the combustion chamber of an internal combustion chamber. The apparatus has a plug which has an electrode (19) from which a high energy spark is generated. The spark causes hydrogen which is introduced into the plasma generation cavity by a fuel line to become plasma. The plasma generation cavity (22) is defined by magnetic field generation means (40). The cavity has an inlet opening adjacent the plasma generation location and an outlet orifice. The plasma is ejected as a plasma jet from the cavity from the orifice. The magnetic field generation means is disposed as a magnetic field coil wound about the cavity. The magnetic field is charged by the discharge of a capacitor at the time of the formation of the plasma in the cavity. The magnetic field accelerates the plasma out of the cavity through the orifice (39) so that the plasma exits as a high velocity jet and achieves effective penetration. Timing means are also included for timing the introduction of hydrogen into the cavity, the discharge of the plasma generating spark and the triggering of the magnetic field.

摘要： L'invention a pour objet un dispositif d'allumage par étincelle pour une turbine à gaz, comportant des moyens électroniques de contrôle du cycle de charge et de décharge d'un générateur d'étincelles de type capacitif.
Les moyens de contrôle comprennent: un générateur de fonction 5 qui délivre une tension de référence fonction de la vitesse de la turbine et éventuellement d'autres paramètres. Un dispositif de contrôle 6 de la charge de la cellule capacitive 9 et un dispositif de commande 7 de la fréquence d'étincelle sont pilotés par la tension de référence. La réallumage en cas d'extinction, est commandé par des moyens opto-électroniques 11, 12, 13 qui pilotent un circuit de réallumage 14 délivrant une tension qui se superpose à la tension de référence.
Le dispositif peut être utilisé pour l'allumage d'une turbine à gaz, notamment dans les turbo compresseurs.

摘要： The ignition system (10) of an engine (particularly for a UAV) has a primary (10a), and a secondary (10b) ignition system to provide redundancy for ‘get you home’ capability should the primary ignition system fail. The secondary ignition provides a lower energy or shorter duration spark than the higher energy or longer duration sparking of the primary ignition system, and is retarded relative to primary sparking. Timing of the secondary sparking can be advanced in the event of primary sparking failure. Fuelling strategy can be shifted from a leaner stratified charge to a richer homogenous charge when relying just on the secondary ignition system for ignition. The secondary ignition system can be of a lower spark energy and/or duration than the primary ignition system, avoiding the cost, complexity and weight of replicating the primary ignition system, and to improve packaging within the engine housing, particularly within the limited payload and space limits of a UAV.
