Description
The utility model relates to motor, particularly the spark plug used of gasoline engine ignition.
As everyone knows, spark plug is an important devices in the ignition device of gasoline engine, the structural type of spark plug is more, one-sided utmost point jag formula spark plug wherein, as Fig. 1, shown in 2, insulator 1 is arranged, the centre electrode 2 of insulator central part and joining wiring screw rod 3 thereof and wiring nut 4 thereof, a housing 5 that matches with the insulator periphery and a joining lateral electrode 6 that is bent to the centre electrode top thereof, the folded end of lateral electrode is made the jag formula structure of V-arrangement, and the spark gap 7 that makes spark plug is between the V-arrangement jag portion of centre electrode 2 and lateral electrode 6.Rely on the screw thread on the housing 5 to be fitted in the gasoline engine combustion chamber during use, connect wiring screw rod 3 and wiring nut 4 and centre electrode 2 with high-pressure ignition wire, lateral electrode 6 is connected and ground connection with motor through housing.After connecting the high voltage pulse that gasoline engine ignition system produces, puncture the spark gap between centre electrode and lateral electrode rapidly, produce electrical spark, compressed inflammable mixture in the ignition engine firing chamber.This spark plug, though two pairs of arcing points are arranged between the V-arrangement jag structure of lateral electrode and the centre electrode, but since lateral electrode to cover in centre electrode over half, the accessibility that electrical spark is spread to inflammable mixture is not good enough, thereby has the inadequate problem of fuel combustion.
Given this, the purpose of this utility model is to provide the good annular lateral electrode formula spark plug of accessibility that a kind of arcing is reliable and electrical spark is spread to inflammable mixture.
The utility model adopts on the basis of above-mentioned spark plug, and the annular that the lateral electrode of spark plug is designed to otch realizes its purpose.
Annular lateral electrode formula spark plug of the present utility model (referring to accompanying drawing), comprise insulated body (1) centre electrode (2) and lateral electrode (6) at interval, above-mentioned lateral electrode is the annular of surrounding centre electrode and at least one otch towards centre electrode (9,14,15) being arranged.
Above-mentioned otch (9) can be V-shaped in interior week.
Above-mentioned otch (14) can take the shape of the letter U in interior week.
Above-mentioned otch (15) can be the in-line of cross-section anchor ring.
The end face (12) of end face of above-mentioned centre electrode (11) and lateral electrode is on same plane.
Annular lateral electrode formula spark plug of the present utility model, after inserting pulsed high-voltage, the ionization gap between the centre electrode of high petential and the annular lateral electrode of zero potential is punctured rapidly, produces electrical spark, the inflammable mixture in the ignition engine cylinder.
Said structure of the present utility model makes it have following advantage and effect.
One, the annular lateral electrode structure of notch shape of the present utility model, the spark gap that makes spark plug is between centre electrode and lateral electrode, form loop configuration, also do not block mutually spread on the direction no any blocking, particularly centre electrode and lateral electrode of electrical spark.This structure, the accessibility that flame is spread to inflammable mixture improves, and the indoor inflammable mixture of engine combustion is fully burnt, and improves the engine running performance, makes motor be easy to start, explosive force is strong, speed-raising is fast; Reduce He (hydrocarbon), Co (carbon monoxide) exhaust emissions amount and fuel consumption.And the electrical spark that between centre electrode and lateral electrode, forms, become the sliding type arcing of not fixing arcing point, thereby can prolong electrode life,
Two, the annular lateral electrode structure of notch shape of the present utility model, particularly V-notch, U-shaped otch, in-line notch features, because notching edge is sharp-pointed, form sharp keen point discharge, this structure is both just under lower pulsed voltage, also can obtain to stablize arcing, thereby can improve the reliability of arcing.
Three, the annular lateral electrode structure of notch shape of the present utility model, particularly V-notch, U-shaped otch, in-line notch features, be in conplane structure with centre electrode end face and lateral electrode end face, make the heat of following electrical spark to produce, can be by otch dissipation, the bad arcing of avoiding temperature to rise and caused.
Four, the annular lateral electrode structure of notch shape of the present utility model, between the notch of lateral electrode and centre electrode, form the arcing point, particularly be adjusted into when identical when the spark gap with each arcing point, the arcing performance is improved, thereby can improve the starting performance of motor.
The utility model is suitable for and the supporting use of all kinds of petrol engines.
Below, the utility model is further described to use embodiment and accompanying drawing thereof again.
