    摘要： A multipoint ignition engine (1) includes a central electrode pair (9), disposed in the center of a combustion chamber (2), for forming a central spark gap (10), and a plurality of peripheral electrode pairs (12) held in a head gasket (15), which has an opening portion having a substantially identical diameter to an opening portion of a cylinder (5) in a position corresponding to the opening portion of the cylinder (5), for forming a plurality of peripheral spark gaps (13) around the inner periphery of the opening portion in the cylinder (5). An air-fuel mixture in the combustion chamber (2), which is obtained by mixing together fuel and air evenly to the stoichiometric air-fuel ratio or a richer/leaner air-fuel ratio than the stoichiometric air-fuel ratio, is ignited using both the central spark gap (10) and the plurality of peripheral spark gaps (13).

    摘要： An object is to provide a spark plug which can improve startability and sooting-up prevention performance of an internal combustion engine in a low temperature environment. Means for solution is a spark plug 1 which includes an electrode 5, an insulator 2, a metallic shell 3, a main ground electrode 30, and at least two auxiliary ground electrodes 40. The spark plug 1 is characterized in that (i) the main ground electrode 30 is disposed so that its distal end portion faces a side surface of a front end portion of the center electrode 5 and forms a main spark discharge gap 38 between the distal end portion and the front end portion of the center electrode 5; (ii) each of the auxiliary ground electrodes 40 is disposed so that a portion of its distal end portion end surface faces an outer circumferential surface of a front end portion of the insulator 2; and (iii) a total area S satisfies an expression S/Av

    摘要： The plug comprises a nut, a coupling extending from the nut and adapted to receive an ignition wire and an insulator extending from the nut and away from the coupling. A positive electrode extends through the insulator. An externally-threaded tubular portion extends from the nut in surrounding relation to the insulator and terminating, short of the insulator end, in a cap that is disposed in spaced relation to the insulator. The cap defines a void having: a central portion into which the positive electrode extends; an annular channel surrounding the central portion; and a plurality of lobes, each positioned with respect to the central portion as the planet gears are positioned with respect to the sun gear in a planetary gear. The cap has a central surface that is axially spaced from the insulator and a convex surface that surrounds and extends to the central surface.
