Abstract: Eine Zündkerze für eine Brennkraftmaschine ist bereitgestellt, die mit einem Spitzenvorsprung ausgestattet ist, der an einen Obersten eines hohlen zylindrischen Gehäuses der Zündkerze angeordnet ist. Die Zündkerze hat ebenfalls einen Mittelelektrode, die in einem Porzellanisolator zurückgehalten ist, der innerhalb des Gehäuses angeordnet ist, und eine Masseelektrode ist mit dem Gehäuse gefügt, um einen Zündfunken auszubilden. Der Spitzenvorsprung dient, um eine Strömung eines durch einen Funken zu zündenden Gases zu richten, der in dem Zündspalt erzeugt wird, und ist geformt, eine radiale Breite aufzuweisen, die sich in einer radialen Richtung des Gehäuses erstreckt, und eine Umfangsbreite, die sich in einer Umfangsrichtung des zylindrischen Gehäuses erstreckt. Die radiale Breite ist größer als die Umfangsbreite. Dies verbessert den Wirkungsgrad im Führen der Strömung des Gases zu dem Zündspalt.

Abstract: An ignition device for an internal combustion engine has a spark plug, an ignition coil, a housing and a mounting portion. The spark plug is for discharging a current to ignite an air-fuel mixture in a combustion chamber of the internal combustion engine. The ignition coil is for supplying the current to the spark plug. The housing encloses the spark plug and the ignition coil therein. The housing has a mounting portion to be disposed in a mounting hole provided in a cylinder head of the internal combustion engine. The mounting portion includes a screw portion a non-screw portion. The screw portion is to be screw-fastened to the mounting hole. The non-screw portion is not to be screw-fastened to the mounting hole.

Abstract: PROBLEM TO BE SOLVED: To provide an ignition control device capable of suppressing output fluctuation between cycles in operating an engine under lean conditions.
SOLUTION: The ignition control device 1 comprises an ignition plug 11 to which voltage is applied in the combustion stroke of the engine; an ignition coil 15 applying high voltage to the ignition plug to generate discharge sparks; an ammeter 18 measuring an ignition current value in the electric discharge of the ignition plug 11; and an ECU 30 performing intermittent control of electric discharge of the ignition plug 11 according to the ignition current value. The ECU 30 acquires the flow of discharge sparks based on information acquired from the ammeter 18 and interrupts electric discharge when observing the flow of electric discharge sparks. Ignition by electric discharge sparks not flowing in each combustion stroke can thereby be achieved to suppress output fluctuation between the cycles.
