Embodiment Construction

[0013] As shown in the figure, the one-piece automobile spark plug includes a threaded metal plug 9 and a center electrode 6 that is penetrated on the axis of the metal plug 9 and is isolated and fixed by a ceramic core 8 .

[0014] The upper end of the metal plug 9 is made into a cylindrical shell 3, and in its inner cavity, the low-voltage coil 4 and the high-voltage coil 5 wound on the wire frame 7 form an ignition coil, and the wire frame 7 is set on the center electrode 6, and the center electrode 6 As the iron core, a step-up transformer is formed.

[0015] The inner cavity of the cylindrical housing 3 is filled and sealed with resin 12, and the resin 12 is epoxy resin.

[0016] Both ends of the high voltage coil 5 are electrically connected to the cylindrical casing 3 and the center electrode 6 respectively.

[0017] Both ends of the low-voltage coil 4 are electrically connected to the cylindrical casing 3 and the lead-out electrode 1 respectively.

[0018] The cylind...

Abstract

The invention discloses an integrated vehicle spark plug, which comprises a metal plug with threads and a center electrode which is inserted in the shaft center of the metal plug and isolated and fixed by a ceramic core, wherein the upper end of the metal plug is made into a tubular shell, an inner cavity of the metal plug is provided with an ignition coil sleeved on the center electrode, the center electrode is used as an iron core, the inner cavity is sealed by filling with resin, the high-voltage output end of the ignition coil is electrically connected with the center electrode, and the lower-voltage input end of the ignition coil is connected with an extraction electrode at the upper end of the tubular shell. Because the ignition coil and the spark plug are designed into one body and no part is exposed out of the whole device, the electric leakage spark-out problem due to watering and cylinder line ageing is solved, and the motor is ensured to reliably work.

Description

technical field [0001] The present invention relates to automobile engine components, especially improvements to ignition systems. Background technique [0002] The ignition system of an automobile engine is mainly composed of a computer or igniter, an ignition coil, and a spark plug. The computer or igniter outputs a DC 12V ignition pulse according to the working timing of each cylinder of the engine. The cylinder line is transmitted to the spark plug of each cylinder to ignite the mixture in the cylinder. [0003] When the car is driving in rainy days, because the connection parts of the sub-cylinder line and the output end of the ignition coil, the spark plug cap, etc. are prone to water, causing high voltage leakage and causing the spark plug to break off, making the ignition of each cylinder of the engine abnormal or even stalled, and the car cannot be driven. . [0004] In addition, after the aging of the sub-cylinder line, it is easy to cause discharge between adjac...
