摘要： A spark plug (100, Fig 2) for an internal combustion engine comprises a tubular metallic shell (120) defining an axial counterbore along which extends an electrically insulating sleeve (12) surrounding a first electrode (16) that cooperates with a second, ground electrode (22) carried by the shell to define a primary spark gap G1. The insulating sleeve carries one or more lateral projections (32) of electrically insulating material spaced from the tip and the metallic shell part extends axially to the vicinity of the projection as a plurality of shell extension elements 121 1 , 121 2 of limited circumferential extent separated by spaces 123 1 , (123)2 that define lateral sleeve exposing openings. The extension elements define with the sleeve projection secondary spark gaps G2 and the openings permit fuel to access the counterbore in the vicinity of the secondary spark gaps and a flame front of fuel ignited by a spark at a secondary gap to pass efficiently into the combustion chamber. The limited exposure of the sleeve to the combustion chamber by the opening spaces and accessibility of the counterbore ensures less fouling and better cooling of the sleeve that enables it to function at higher engine temperatures. The extension elements may be capped by a circumferentially extending ring (325, Fig 4) or the elements and intervening spaces may be defined by a tubular wall with through apertures (427, Fig 5).

摘要： A spark plug (30; 40) comprises an electrically-insulating sleeve (12), a first electrode (16), an electrically-conducting shell (20) surrounding said sleeve, and a second electrode (22) mounted on said shell. The electrodes (16 and 22) define a spark gap (G1) of the plug. The shell (20) has an end portion (20c) terminating at an end surface (20b) of the shell. The sleeve (12) extends past said end portion (20c) with a clearance therebetween and extends beyond said end surface (20b). The sleeve (12) has at least one projection (32) which projects from the sleeve (12) and reduces said clearance in the region of the end surface (20b), thereby forming a secondary spark gap (G2).

摘要： A corona ignition system for providing a corona discharge (24) includes an igniter (20) having an electrode (26) with an asymmetrical firing tip (28) relative to an electrode center axis (a e ). The firing tip (28) includes a first surface area (A 1 ) facing the fuel injector (42) which is greater than a second surface area (A 2 ) facing a cylinder block (32). The first surface area (A 1 ) presents a projection (60) having a sharp edge, and the second surface area (A 2 ) presents a round outward surface (62). Accordingly, a radio frequency electric field emitted from the first surface area (A 1 ) provides a robust corona discharge (24) in a flammable area at an outside edge (30) of the fuel spray. No electric field is emitted from the second surface area (A 2 ), and no power arcing occurs between the second surface area (A 2 ) and the cylinder block (32).

摘要： A corona ignition system 20 includes a corona drive circuit 26 and an auxiliary energy circuit 28. The energy circuit 28 stores energy during a standard corona ignition cycle. When arc discharge occurs or corona discharge switches to an arc discharge, the energy circuit 28 discharges the stored energy to the electrode 30 to intentionally maintain a robust arc discharge 29 and thus provide reliable ignition. The stored energy is transmitted to the electrode 30 over a predetermined period of time. The arc discharge is detected and an arc control signal 60 is transmitted to the energy circuit 28, triggering discharge of the stored energy to the electrode 30. The stored energy can be transmitted to the electrode 30 along a variety of different paths. The voltage of the stored energy is typically increased by an energy transformer 70 before being transmitted to the electrode 30.
