摘要： A spark plug according to the present invention includes a metal shell, an insulator retained in the metal shell, a center electrode secured in the insulator, and a ground electrode. The center electrode includes a base member and a thin member thinner the base member. The ground electrode includes a base member fixed to the metal shell and a protruding member that protrudes from the base member and has an end face with an inner and an outer edge. When the insulator is clean, sparks can be discharged between the thin member and the inner edge. When the insulator is fouled with carbon, sparks can be discharged between the base member and the outer edge to self-clean the insulator. Dimensional parameters and relationships are specified in the spark plug, so that the spark plug can induce spark discharges with a low discharge voltage while securing an excellent self-cleaning capability thereof.

The center electrode is secured in the insulator and has an end portion that protrudes from the insulator and has an end edge. The ground electrode includes a base member fixed to the metal shell and a protruding member joined to the base member. The protruding member protrudes from a surface of the base member and has a hollow end face that faces the end portion of the center electrode through a spark gap. The end face of the protruding member has an inner edge and an outer edge, both of which face the end edge of the end portion of the center electrode. With the above configuration, the spark plug can induce spark discharges with a low discharge voltage while securing the ignition capability thereof.

摘要： An ignition device sets a total discharge period, each discharge period and each intermittent period of a multiple discharge are set by a control map in addition to the setting of a throttle opening, fuel injection timing, fuel injection period and ignition timing for the range of non-stratified charge combustion, when a direct injection-type engine operates in the range of stratified charge combustion. Ignition signals including a plurality of rises and falls are outputted in time with a specific ignition timing after fuel injection. Thus a plurality of sparks are generated from the spark plug, ensuring reliable ignition in response to changes in the concentration of sprayed fuel within the operation range for stratified charge combustion.

A gas guiding sections equipped with slopes that slope inwardly as they approach toward a tip side from a circumference surface of the housing and guide surfaces that are disposed on both sides in a circumferential direction of the slopes are formed in a tip part of the housing. The gas guiding sections are formed in the circumferential direction within a 90-degree range measured relative to the center of the earth joint section, which is a junction of the housing and the earth electrode, in the circumferential direction. When the spark plug is mounted to the engine, it is constituted so that the gas guiding sections are projected into a combustion chamber.
