According to the material, this _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ In the following, the embodiments of the present invention and their implementations are further described. FIG. 3 is not shown. The present Mars plug 100 includes a conductive housing 102 and a ceramic body 120. The conductive housing 102 is in the form of a hollow shell and surrounds the inner bore. The ceramic insulator 12 is coated with the center electrode 130 and housed in the inner hole / in the same. In the present embodiment, the outer side of the conductive housing 102 has an outwardly inclined slope 104 and external threads 108. The external thread 1〇8 is connected to the inclined surface 1〇4, and the inclined ship system is formed outside the end portion of the conductive housing 1Q2. However, in other different embodiments, the bevel 1 〇 4 may also be curved or otherwise shaped. The center electrode is preferably a straight rod. However, in other different embodiments, a tapered or other shape may be provided at the top end of the center electrode 130. A gap 132 is maintained between the ceramic insulator 12A and the conductive housing (10). The gap 132 is distributed between the ceramic insulator 120 and the conductive housing 1〇2 with a certain height. In the embodiment shown in FIG. 3, the height of the end surface of the conductive housing 1〇2 with respect to the opening of the inner hole 11 is preferably higher than the height of the end surface of the center electrode 130, and the height of the end surface of the center electric j 130 is preferably high. The height of the end face of the ceramic insulator 12〇. The outer side wall 1〇5 of the conductive housing 102 is protruded from the outer surface of the inner hole 130, and the end surface of the center electrode 13 is also protruded from the surface of the ceramic insulator 120. The outer surface of the conductive housing 1〇2 protrudes from the center electrode 130 by a difference of 5 to 2 mm. Or, the end surface of the center electrode 130 is lower than the side wall 105 of the conductive housing 102 opposite to the opening of the inner hole 11 ,, and the end surface of the ceramic insulator 120 is also lower than the end surface of the center electrode 13 〇. Figure 4 is a diagram showing another embodiment of the creation of a Mars plug. In this embodiment, the conductive housing 102 further includes at least one hole 15〇. However, in other different real 7 M332319 embodiments, a plurality of holes 丨 5 亦可 may also be provided. The hole 15 is horizontally connected to the gap 132 from the outer side wall 1〇5 of the conductive housing 102, and the height of the hole 15〇 is lower than the height of the end face of the ceramic insulator 12〇. As shown in Fig. 4, the pores 150 preferably have a pore diameter ranging from 2 to 14 mm. In other words, the peripheral surface of the hole 15 不 is not higher than the end face of the opening of the inner hole 11 陶瓷 of the ceramic insulator 12 。. In other various embodiments, however, the height of the holes 150 may be equal to or at the height of the end faces of the ceramic insulator 120. Further, in the embodiment shown in Fig. 4, the end portion of the inclined surface 1〇4 of the conductive housing 102 has a tip end surface. As shown in Fig. 5 and Fig. 6, when the spark plug is turned on and discharged, the current of the piezoelectric element has the characteristic of tip discharge, and it is preferred to form a loop at the lowest resistance. However, it is also possible that the current will conduct a circuit at the nearest distance (i.e., arc spark 170). In the embodiment shown in FIG. 5, the arc spark 170a is formed between the top end surface 1〇6 and the end surface of the center electrode 130, or an arc spark is formed between the end surface of the center electrode 130 and the inner side wall of the conductive housing 1〇2. 170b. In the embodiment shown in Fig. 6, the arc spark no is preferably formed by forming a slanted continuous face 18〇 between the top end face 106 and the center electrode 13〇. However, in other various embodiments, a horizontal arc spark can also be formed between the center electrode 13A and the inner sidewall of the conductive housing 102. As used herein, a continuous face 18 〇 means that an arc spark 170 can be formed at an angle of either of the inner bores 110 relative to 360 degrees. However, in other different embodiments, it is also possible to form a continuous face 180 of a portion or segment. Further, in the embodiment shown in Fig. 5, it is preferable to provide a corresponding hole 150. The height of the two holes 150 is lower than the height of the end face of the ceramic insulator 120. Therefore, when the mixed oil and gas 230 enters the hole 150, the sidewall of the ceramic insulator 120 is first impacted, and no direct impact or interference is formed on the center electrode 130. Arc sparks 170a, 170b between the end face and the top end portion 1〇6 or between the end face of the center electrode 13〇 and the inner wall of the guide 8 M332319. In addition, the arrangement of the holes 150 also facilitates the mixing of the oil and gas 230 into the inner bore 132 to assist in igniting the mixed oil and gas 230 to increase the chance of ignition. Moreover, the arrangement of the holes 150 also helps the grease or impurities remaining in the gap 132 to escape from the holes 150 without affecting the formation of the arc sparks 170a, 170b. FIG. 7 is a diagram showing an embodiment in which a spark plug is created in an engine. The Mars plug 1 is locked in the cylinder of the engine 2 by means of external threads 108 of the conductive housing 102. In the embodiment shown in FIG. 7, when the mixed oil and gas 230 (ie, a mixture of fuel and gas) enters the combustion chamber 210, the inclined surface 104 having an angle guides and increases the rapid distribution of the atomized fuel gas. Further, the arc spark 170 that has been ignited is accelerated to contact and burn. In particular, when the throttle is heavy, the large amount of mixed oil and gas 230 formed by the rolling will quickly enter the combustion chamber 21〇, and is hidden in the conductive housing 1〇2 and between the center electrode 130 due to the protection of the conductive housing 102. The formed arc spark 170 is not directly impacted by the accelerated mixed oil and gas 230. In other words, the Mars plug 100 can still ignite and burn in this high-pressure and fast fuel environment, so that the engine 2 〇〇 generates power. This creation has been described by the above related embodiments, but the above embodiments are merely examples for implementing the creation. It must be pointed out that the disclosed embodiments do not limit the situation. Modifications (4) and modifications and equal settings of the original Lin Zu are included in the attached request.
