Embodiment 1

[0036] see Figure 4 , Figure 5 As shown, this embodiment shows a spark plug 200, including a spark plug shell 201, an insulator 202 and a central electrode 203;

[0037] The spark plug shell 201 is provided with a hollow cavity 204, the insulator 202 is fixed at the lower part of the hollow cavity 204, the central electrode 203 is covered in the insulator 202, and the top of the central electrode 203 extends through the insulator 202 and is exposed. In the hollow cavity 204 of the spark plug housing 201; the insulator 202 can be made of a material with high thermal conductivity, such as sintered alumina ceramic material;

[0038] Above the central electrode 203 is provided with a negative electrode ignition unit 205, the negative electrode ignition unit is cylindrical, and the inner wall of the hollow cavity 204 at the lower edge of the negative electrode ignition unit 205 is provided with a blocking device 206; the hollow cavity 204 The upper edge of the upper edge is nar...

Embodiment 2

[0041] see Image 6 As shown, embodiment 1 is repeated, the difference is that: the wall of the hollow cavity 204 of the spark plug housing 201 is provided with an annular protrusion 209, and the annular protrusion 209 divides the hollow cavity 204 into a conductive first chamber 210 and the second chamber 211; the first chamber 210 and the second chamber 211 communicate through the channel 212 in the middle of the annular protrusion 209; the shortest distance from the central electrode 203 to the annular protrusion is 1 mm, and the central electrode to the negative electrode The shortest distance of the ignition unit is 2 millimeters; the setting of the above-mentioned distance makes the shortest distance from the central electrode to the top of the annular protrusion exceed 1 millimeter compared with the prior art, which increases the cut-off of the communication channel between the first chamber and the second chamber. Area; can effectively reduce the impact of the spark pl...

Embodiment 3

[0044] join Figure 7 , Figure 8 As shown, repeat Example 2, the difference is that: the negative ignition unit 205 is provided with seven exhaust holes 208, which are evenly arranged on the negative ignition unit 205, and the area of ​​the exhaust holes 208 occupies 50% of the cross-sectional area of ​​the negative sparking unit 208; the shortest distance from the central electrode 203 to the negative sparking unit 205 is 1.1 mm, and the shortest distance from the central electrode 203 to the ring protrusion 209 is 2.1 mm.

Abstract

The invention discloses a spark plug, comprising a spark plug shell, an insulator and a center electrode, wherein a hollow cavity is arranged in the spark plug shell, the insulator is fixedly arranged at the lower part in the hollow cavity, the center electrode is wrapped by the insulator, the upper top of the center electrode penetrates through the insulator to be exposed in the hollow cavity of the spark plug shell, a cathode sparking unit is arranged above the center electrode, the cathode sparking unit is fixed on the wall of the hollow cavity of the spark plug shell and provided with a vent that longitudinally penetrates through the cathode sparking unit, and the closest distance between the center electrode and the wall of the hollow cavity is more than that between the center electrode and the cathode sparking unit. According to the spark plug, possible impact of the spark plug to an existing automobile computer system caused by rapid, sufficient and complete combustion in a sparking and combusting period can be effectively reduced, fuel saving of the spark plug is effectively achieved, power is enhanced and sufficient is greatly reduced.

Description

technical field [0001] The invention relates to an internal combustion engine of an automobile, in particular to a spark plug. Background technique [0002] It is well known to use a spark plug to ignite the air and fuel mixture in the combustion chamber of a spark ignition engine. [0003] The performance of the spark plug can directly affect the performance of the engine; if the spark plug does not properly ignite the air and fuel mixture located in the combustion chamber, there will be at least partially unburned fuel, resulting in loss of power, reduced fuel efficiency and increased emissions of hydrocarbons. [0004] In order to solve the problem of incorrect ignition, Chinese patent 201180045087.9 discloses a spark plug (see figure 1 with figure 2 As shown), the use of the spark plug can significantly enhance the power of the car, the enhanced power is about 10%, can reduce the exhaust emission by nearly 50%, and can also realize the fuel saving of the spark plug b...
