摘要： By grounding a metal first housing, radiation noise generated from the coupling circuit is shielded. Further, by enclosing the first housing in a metal second housing in a manner such that the first housing and the second housing do not come into contact with each other, and grounding the second housing by connecting the second housing to an engine block, radiation noise generated by the capacitive component between the coupling circuit and the first housing is shielded by the second housing. As a result, the influence of this noise on peripheral devices of the high frequency discharge ignition device can be suppressed.

摘要： An aim of the present invention is, in a plug for high frequency emission disposed at an end of a casing having an emission antenna, to suppress a high frequency noise emitted from the emission antenna. The present invention is directed to a plug for high frequency emission including a transmission line for transmitting an electromagnetic wave, an emission antenna for emitting the electromagnetic wave supplied via the transmission line, and a casing constituted by a cylindrical shaped conductor, provided with the emission antenna at one end of the casing, and accommodating therein the transmission line extending from the emission antenna toward the other end of the casing. Inside of the casing, a central conductor electrically connected to the emission antenna and an outer conductor spaced apart from and surrounding the central conductor are embedded in an insulator so as to collectively constitute the transmission line, and the outer conductor is disposed in and held in non-contact with the casing.

摘要： A corona igniter (20) comprises a central electrode (22) surrounded by an insulator (26), which is surrounded by a conductive component. The conductive component includes a shell (34) and an intermediate part (36) both formed of an electrically conductive material. An outer surface (50) of the insulator (26) presents a lower ledge (52), and the intermediate part (36) is typically attached to the insulator (26) above the lower ledge (52) prior to inserting the insulator (26) into the shell (34). The conductive inner diameter (Dg) is less than an insulator outer diameter (Dio) directly below the lower ledge (52) such the insulator thickness (ti) increases toward the electrode firing end (40). The corona igniter (20) can be reversed-assembled by inserting an upper end (42) of the insulator into a firing end (56) of the shell.

摘要： In an internal combustion engine that causes a predetermined gas flow in a combustion chamber, discharge plasma generated by a discharge device is caused to effectively absorb energy of an electromagnetic wave emitted from an electromagnetic wave emission device. At a time when a discharge operation and an emission operation are simultaneously performed so as to ignite a fuel air mixture, an emitting position of the electromagnetic wave on an antenna during the emission operation is located downstream of the discharge gap in a direction of the gas flow at the discharge gap so as to face toward the discharge plasma that has been drifted due to the gas flow.

摘要： An ignition system (10) comprises a high voltage transformer (12) comprising a primary winding (12.1) and a secondary winding (12.2). A primary resonant circuit (26) is formed by the primary winding (12.1) and a primary circuit capacitance (24). A secondary resonant circuit (16) is formed by an ignition plug (14), as a load, the secondary winding (12.2); the ignition plug (14) being represented by a secondary circuit capacitance (18) and a secondary circuit load resistance (Rp) put in parallel. Said load resistance value varies during an ignition cycle. The primary resonant circuit (26) and the secondary resonant circuit (16) have a common mode resonance frequency (fc) and a differential mode resonance frequency (fd). A controller (28) is configured to cause a drive circuit (22) to drive the primary winding at a frequency, which is either the common-mode resonance frequency (fc) or the differential mode resonance frequency (fd) and is connected to a feed-back circuit (50) to adapt the frequency of the primary winding to the variable load resistance.

摘要： An ignition device is provided, the ignition device comprises a coaxial structural body comprising an inner conductor 2, an outer conductor 3, and an insulator 4 that insulates both the conductors 2 and 3, which are coaxially provided with one another along an axial direction. A connection terminal 5 is arranged at one axial end side of the coaxial structural body and connecting the inner conductor 2 and the outer conductor 3 to the electromagnetic wave oscillator MW. The inner conductor 2 has a linearly extended part protruding at another axial end side of the coaxial structural body extending outwards from the outer conductor 3 in the axial direction and a spirally extended part continuously extending from the linearly extended part in a reversed direction and in a spiral manner that winds around the linearly extended part of the inner conductor 2 in a predetermined number of turns around the linearly extended part such that the inner conductor 2 forms a resonance structure and the spirally extended part 20 with the resonance structure is obtained. A diameter and a length of the inner conductor 2 that is extended outwards from the outer conductor 3, and the number of turns of the spirally extended part of the inner conductor 2 are determined such that a capacitive reactance XC and an inductive reactance XL of the spirally extended part are substantially equal to each other.

摘要： A method for actuating a spark plug, in which the spark plug is assigned a first ignition coil and second ignition coil. Triggered by a start signal, the primary winding of the first ignition coil is charged, and the primary winding of the second ignition coil is charged with a delay D, for which 0≦D, by supplying a direct current, wherein, whilst each primary winding, is charged, the respective secondary winding is blocked; the primary current supplied to the primary windings is measured; after a period T, the primary winding of the first ignition coil is discharged, and with the delay D the primary winding of the second ignition coil is discharged; the secondary current flowing through the spark plug is measured; thereafter the primary windings of the first and second ignition coil start to be charged alternately when the secondary current falls below a threshold; the primary windings are discharged alternately when the primary current reaches an upper threshold; the above steps are repeated until the duration of discharge between two electrodes of the spark plug 1 reaches a predefined value Z.
