摘要： In an ignition plug, since a ground electrode is formed in a thin-rod-shape or a mesh-like shape, sufficiently strong radicals are locally generated by a barrier discharge, an anti-inflammation effect by the electrode is small, and the growth of a flame is hardly hindered. Furthermore, by making the thickness dimension of a second dielectric facing a discharge region uniform, the barrier discharge is spread over the surface of the second dielectric, the generation of the radicals is maintained, and combustibility after ignition is promoted. Furthermore, because an end portion of a high voltage electrode and a ground electrode are disposed to face each other within a combustion chamber, a fuel gas introduced into the combustion chamber is liable to flow into the discharge region, and is easily ignited by the radicals generated due to the discharge.

摘要： A quarter wave coaxial cavity resonator for producing corona discharge plasma from is presented. The quarter wave coaxial cavity resonator has a folded cavity made of opposing concentric cavity members that are nested together to form a continuous cavity ending in a aperture. A center conductor with a tip is positioned in the cavity. The folded cavity advantageously permits the coaxial cavity resonator to resonate at a lower operating frequency than an unfolded quarter wave coaxial cavity resonator of the same length. Embodiments of the quarter wave coaxial cavity resonator use narrower apertures to reduce radiative losses, and include center conductors that are reactive load elements, such as helical coils. When a radio frequency (RF) oscillation is produced in the quarter wave coaxial cavity resonator, corona discharge plasma is formed at the tip of the center conductor. The corona discharge plasma can be used to ignite combustible materials in combustion chambers of combustion engines.

摘要： Described is a supply circuit for a corona ignition device, with an input for connection to a direct voltage source, a first converter, a second converter, and an output for connecting a load. The two converters each generate an output voltage, which is provided on its secondary side and exceeds the input voltage. The two converters each contain a transformer that galvanically separates the primary side of the converter from its secondary side. At least one transistor switch is arranged between the input and primary side of the two converters for pulse width-modulation of the input voltage. The primary side of the second converter is connected in parallel with the primary side of the first converter, the secondary side of the second converter is connected in series with the secondary side of the first converter, the secondary sides of the two converters are each bridged in this series connection by at least one diode, so that an output voltage can be provided at the output of the supply circuit even given a failure of one of the two converters.

摘要： An ignition device is provided, which can boost an electromagnetic wave supplied by a resonance structure, and cause a discharge by enhancing a potential difference between a discharge electrode and a ground electrode, and even though such a structure of the ignition device, a downsize and a thickness reduction, specifically, the thickness reduction can be achieved. On a main surface of a rectangular insulting substrate (2), an input electrode (3), a coupling electrode (4), a discharge electrode (6), and a ground electrode (7), are provided. The input electrode (3) is connected to an outside terminal on one shorter side. The coupling electrode (4) is capacity-coupled with the input electrode (3). The discharge electrode (6) is connected to the coupling electrode (4) on the other shorter side through a coupling line (5). The ground electrode (7) is, on both longer sides of the main surface of the rectangular insulating substrate (2), capacity-coupled with the coupling electrode (4) and capacity-coupled with the coupling line (5), and extended to the other shorter side. A resonance circuit includes a capacitor constituted by the capacity coupling and an inductor constituted by the coupling line (5). Thereby, the electromagnetic wave supplied from the outside terminal into the input electrode is resonated, a potential difference between the discharge electrode (6) and the ground electrode (7) is enhanced, and then, a discharge is caused.

摘要： An ignition plug wire for an internal combustion engine has an elongated conductor with a programmable capacitor module disposed in-line with the elongated conductor. The programmable capacitor module is configured to step up or convert the ignition voltage normally supplied by an ignition coil to a plasma voltage. An inventive ignition plug if configured such that the anode enclosed within the insulator includes or is replaced by a voltage converting module designed to convert the ignition voltage into a plasma voltage. The voltage converting module consists of a semiconductor circuit, a composite semiconductor material, or a capacitor.

摘要： A system and method for providing multiple fast rising pulses to improve performance efficiency. In one approach, multiple fast rising pulse power is employed to improve fuel efficiency and power of an engine. The system and method can involve a transient plasma plug assembly intended to replace a traditional spark plug. Alternatively, an approach involving a pulse generator and a high voltage pulse carrying ignition cable is contemplated.

摘要： An ignition system includes: a step-up transformer having a primary side and a secondary side; an electrical energy source configured to be selectably connected to the primary side; a spark gap which is configured to guide a current transferred by the step-up transformer to the secondary side. The step-up transformer has a bypass for transferring electrical energy from the electrical energy source to the secondary side. The ignition system is configured to couple electrical energy in series or in parallel to the secondary side of the high voltage generator for the purpose of maintaining an ignition spark as an electrical voltage in the form of a controlled pulse sequence, e.g., within the kilo-hertz range.

摘要： In an internal combustion engine ignition coil apparatus, a high-voltage supplying portion has: a protector that is bonded to an ignition coil main body, an electrical conductor, and a resistor that is connected in series between the ignition coil main body and the electrical conductor, and that reduces conductive noise. An electromagnetic wave absorber that shields radiated noise that is generated in the high-voltage supplying portion is mounted to an engine block so as to surround the protector and the resistor. An end surface of the resistor near the ignition coil main body is disposed so as to be aligned with an end surface of the electromagnetic wave absorber near the ignition coil main body.
