摘要： A corona igniter assembly 20 comprises an ignition coil assembly 22, a firing end assembly 24, and a metal tube 26 connecting the ignition coil assembly 22 to the firing end assembly 24. A rubber boot 28 is disposed in the metal tube 26 and compressed symmetrically between a coil output member 30 of the ignition coil assembly 22 and an insulator 42 of the firing end assembly 24. Thus, the rubber boot 28 fills any air gaps and provides a hermetic seal between the ignition coil assembly 22 and the firing end assembly 24 to prevent unwanted corona discharge from forming from those air gaps.

摘要： An igniter assembly comprising an ignition coil assembly connected to a firing end assembly by an extension, with a valve assembly disposed in a pressure chamber of the extension, is provided. The valve assembly includes a valve stem biased toward the ignition coil assembly by a spring to seal the pressure chamber. The valve assembly is used to evacuate contents from the pressure chamber by pressing the valve stem toward the spring and allowing contents of the pressure chamber to travel through and past the valve stem and out of the pressure chamber. The valve assembly is also used to fill the pressure chamber with an insulating medium by pressing the valve stem toward the spring and allowing the insulating medium to travel through and past the valve stem and into the pressure chamber after evacuating the contents out of the pressure chamber.

摘要： A voltage transformer circuit is described for supplying a spark plug with ignition energy and for ionic current measurement. A transformer of the circuit generates a secondary voltage from a primary voltage and applies the secondary voltage to the spark plug to ignite an electric arc. Using a current effected by the secondary voltage, a capacitor is charged to a breakdown voltage of a Zener diode bridging the same, via a first branch, which leads from the transformer to a first of two sides of the capacitor. The primary voltage is disconnected from the transformer in order to extinguish the electric arc. The capacitor delivers charges for an ionic current via a second branch, which connects the second side of the capacitor to the transformer. A measuring signal of the ionic current is obtained by measuring a voltage drop at a measuring resistor.

摘要： An ignition apparatus for an internal combustion engine is provided which includes a state-of-discharge determiner working to determine whether a center and a ground electrode of a spark plug are electrically conducting with each other or insulated from each other. When the center and ground electrodes are determined to be conducted with each other, the ignition apparatus alters controlled conditions of a high-frequency power supply which supplies a high-frequency power to the spark plug so as to decrease an average of a primary voltage outputted from the high-frequency power supply to the spark plug, thereby reducing an actual current flowing between the center and ground electrodes of the spark plug. This eliminates the risk of mechanical wear of the center and ground electrodes which usually arises from the flow of high current between the center and ground electrodes, thus resulting in an increase in service life of the spark plug.

摘要： A plasma generator comprises a radio frequency power source, a coaxial cavity resonator assembly, and a direct current power source. The radio frequency power source provides a voltage supply of radio frequency power having a first ratio of power over voltage. The resonator assembly includes a center conductor coupled to the radio frequency power source, and also includes a virtual short circuit. The direct current power source is connected to the center conductor at the virtual short circuit, and provides a voltage supply of direct current power having a second ratio of power over voltage that is less than the first ratio.

摘要： A high frequency plasma ignition device for the ignition of a fuel/air mixture in a combustion chamber of an internal combustion engine, having a series resonant circuit of an electric inductor and an electric capacitor connected in series, and a high frequency generator with a first electrical terminal and a second electrical terminal for the resonant excitation of the series resonant circuit, a first electrical contact point being provided in which one end of the capacitor and one end of the inductor are connected to one another electrically. An electrical connecting device connects the high-frequency generator to the inductor and to the capacitor such that an output signal of the high-frequency generator is applied to the series resonant circuit. An electric voltage is applied across the capacitor for igniting a plasma between free ends of a first and second electrode. An electric voltage is further applied to maintain the plasma after ignition.

摘要： An internal combustion engine has an internal combustion engine body formed with a combustion chamber and an ignition device that ignites an air-fuel mixture in the combustion chamber. Repetitive combustion cycles, including ignition of the air-fuel mixture by the ignition device and combustion of the air-fuel mixture, are executed. The internal combustion engine further has an electromagnetic (EM) wave-emitting device that emits EM radiation to the combustion chamber; a plurality of receiving antennas located on a zoning material that defines the combustion chamber, where the antennas resonate to the EM radiation emitted to the combustion chamber from the EM wave-emitting device; and a switching means that switches the receiving antenna resonating to the EM radiation emitted to the combustion chamber from the EM wave-emitting device among the plurality of receiving antennas.
