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
The present invention relates to automotive engine component, particularly to the improvement of ignition system.
Background technology
The ignition system of automobile engine mainly is made up of computer or igniter, ignition coil, spark plug, computer or igniter are exported direct current 12V firing pulse opportunity according to the work of each cylinder of engine, this pulse direct current boosts to more than 100,000 volts through ignition coil, be transferred to the spark plug of each cylinder by cylinder separating line, to the ignition of mixed gas in the cylinder.
Automobile owing to patch position, the spark plug cap etc. of cylinder separating line and ignition coil output are located easy trickle, causes the high pressure electric leakage and causes the spark plug cutoff in the rainy day driving process, makes each cylinder igniting of engine undesired even flame-out, and automobile can't travel.
In addition, after cylinder separating line is aging, easily cause the discharge between the metal parts such as discharge, cylinder separating line and motor body between each adjacent lines, also can make each cylinder of engine light a fire undesired even can't start.
Summary of the invention
The object of the invention is to provide a kind of igniter of not having high-pressure connection line, to solve because of water inlet, the aging undesired problem of engine operation that causes that the high pressure electric leakage causes of electric wire.
The present invention adopts the structure that ignition coil and spark plug are combined as a whole, concrete scheme is: integrated car plug, comprise the metal closures that is shaped on screw thread, be located in the metal closures axle center and isolate and fixing central electrode with ceramic core, tubular shell is made in the metal closures upper end, be provided with ignition coil in its inner chamber, ignition coil is enclosed within on the central electrode, with the central electrode is iron core, seal with resin dosing equipment in the inner chamber, the high-voltage output end of ignition coil is electrically connected with central electrode, and the low pressure input is connected on the extraction electrode of tubular shell upper end.
Tubular shell is the hexagonal prismoid shape.
The discharge termination of central electrode is welded with the tungsten-molybdenum alloy electrode.
Advantage of the present invention is: because ignition coil becomes an integral body with spark plug design, ignition coil is encapsulated in the tubular shell of spark plug, and the extraction electrode place is a low-voltage, and whole device does not have the high pressure exposed part, has solved the cutoff problem that electric leakage causes behind the trickle; Cylinder separating line directly is connected with computer or igniter, is the 12V low-voltage, has solved the cutoff problem that tracking causes, has guaranteed the reliably working of engine.
Description of drawings
The invention will be further described with embodiment with reference to the accompanying drawings below.
Accompanying drawing is a cross-sectional view of the present invention.
Mark among the figure: 1 extraction electrode, 2 seal cap, 3 tubular shells, 4 low-voltage coils, 5 high-tension coils, 6 central electrodes, 7 coil holders, 8 ceramic cores, 9 metal closures, 10 tungsten-molybdenum alloy electrodes, 11 lateral electrodes, 12 resins.
Embodiment
As shown in the figure, integrated car plug comprises the metal closures 9 that is shaped on screw thread, is located in metal closures 9 axle center and isolates and fixing central electrode 6 with ceramic core 8.
Tubular shell 3 is made in metal closures 9 upper ends, and in the chamber, the low-voltage coil 4 and the high-tension coil 5 that are wound on the coil holder 7 are formed ignition coil within it, and coil holder 7 is enclosed within on the central electrode 6, is iron core with central electrode 6, forms a step-up transformer.
With resin 12 perfusion sealings, resin 12 is an epoxy resin in tubular shell 3 inner chambers.
The two ends of high-tension coil 5 are electrically connected with tubular shell 3 and central electrode 6 respectively.
The two ends of low-voltage coil 4 are electrically connected with tubular shell 3 and extraction electrode 1 respectively.
Tubular shell 3 is the hexagonal prismoid shape, is beneficial to sleeve, spanner loading and unloading.
In order to prolong the useful life of electrode, the discharge termination of central electrode 6 is welded with tungsten-molybdenum alloy electrode 10.
During use, change the spark plug of engine into this integrated car plug, extraction electrode is connected to common wiring on the igniting output of computer or igniter and gets final product.
