Abstract
The utility model discloses a heterotype spark plug of a gasoline internal combustion engine. The utility model is structurally characterized in that a bypass electrode is added based on a central electrode and a lateral electrode of a traditional spark plug, the bypass electrode sparks jump immediately when the lateral electrode does not spark jump because of various aspects, such as carbon, voltage and current, etc. Thus, when sparks appear, sparks jump in turn to guarantee 100 percent spark jump of the spark plug. Under the condition of the same current intensity, mixed inflammable gas in an air cylinder can burn sufficiently and the exhaust air fits the criteria of environmental protection.
Description
Technical field
The utility model relates to a kind of gasoline engine spark plug.
Background technology
As everyone knows, the single-sided electrode gasoline engine spark of traditional structure is plugged with insulator, cylindrical central electrode of insulator central part and wiring screw rod thereof and wiring nut, a housing that cooperates with the insulator periphery and a joining lateral electrode that is bent to " L " shape on the central electrode top, the spark gap of spark plug is between central electrode and lateral electrode, this two polar spark plugs are because carbon distribution, voltage, not arcings of each side reason such as undercurrent, break down continually, and because two clearance between poles are little, the spark length that produces during work is short, a little less than the ignition ability, thereby causes combustion mixture to be difficult for being lighted, the combustion mixture incomplete combustion, engine power is descended, and oil consumption increases, and goes back the discharge of noxious gases contaminated environment simultaneously.
China utility model patent CN2105571U discloses a kind of gasoline engine three polar spark plugs, single lateral electrode spark has been plugged with bigger improvement, its structure is to increase by two lateral electrodes that specification framework is identical on the basis of single lateral electrode in addition, three lateral electrodes that are " L " type, 120 degree each other are equally spaced around central electrode, the lateral electrode termination is equidistant covers on the central electrode for each, but still there is following shortcoming in it:
1, since lateral electrode almost shield whole discharge end faces of central electrode, make electric spark pass on property relatively poor, thereby have the inadequate problem of fuel combustion to burning mixture;
2, the carbon distribution growth rate is fast, influences the useful life of spark plug;
3, three lateral electrode manufacturing processing are comparatively complicated, the cost height.
Summary of the invention
The purpose of this utility model provides a kind of special-shaped spark plug, occurs arcing phenomenon in turn when producing spark, guarantees 100% arcing, and under same current strength condition, burning mixture is fully burned, and the waste gas of discharge meets the standard of environmental protection.
The purpose of this utility model is by providing a kind of spark plug with following structure to realize that this spark plug comprises: spark plug cock body, central electrode, lateral electrode, other electrode.
Concrete structure below in conjunction with the special-shaped spark plug of description of drawings:
Description of drawings
Fig. 1 is the utility model structural representation;
Fig. 2 is the utility model vertical view.
Embodiment
From Fig. 1, Fig. 2 as seen, the utility model comprises spark cock body (1), central electrode (2), lateral electrode (3) and other electrode (4), wherein lateral electrode (3) is identical with the spark plug of single lateral electrode, other electrode (4) is installed in central electrode (2) next door, and to be positioned at the central electrode with lateral electrode (3) be on the same circumference in the center of circle, its angle is not less than 90 degree, the distance of other electrode tip and central electrode sidewall distance and lateral electrode and central electrode is 1.2~1.5mm, when lateral electrode because carbon distribution, voltage, during not arcings of each side reason such as electric current, the arcing at once of so other electrode, play a well compensation substitution effect, the phenomenon of arcing in turn when producing spark, occurs, guarantee 100% arcing.Under same current strength condition, the combustion mixture in the cylinder is fully burned, and the waste gas of discharge meets the standard of environmental protection.Special-shaped spark plug is when gasoline starting and anxious accelerated service, and two electrodes can produce spark continuously, guarantee that gasoline engine has good startability, idle stability and anxious acceleration.
Claims (3)
1, the special-shaped spark plug of a kind of gasoline engine comprises spark plug cock body (1), central electrode (2), lateral electrode (3), it is characterized in that also including other electrode (4), and this side electrode (4) electrode tip bends towards central electrode.
2, spark plug as claimed in claim 1 is characterized in that the above-mentioned other electrode tip and the distance of central electrode sidewall and the distance on lateral electrode elbow and central electrode summit are 1.2~1.5mm.
3, spark plug as claimed in claim 1 is characterized in that it is on the same circumference in the center of circle that above-mentioned lateral electrode and other electrode are positioned at the central electrode, and its angle is not less than 90 degree.
