Abstract
The utility model relates to an improve partial radiating device of spark plug, including compressor, compressor power and compressed air pipe, characterized by compressor is by compressor power drive, and compressed air pipe comprises house steward and manifold, and the entry of house steward links to each other with the compressor, along the manifold that house steward's axial setting and spark plug high-voltage line sheath are corresponding on house steward's pipe wall, the entry and the house steward intercommunication of manifold, and spark plug high-voltage line sheath is aimed at in the export of manifold. Because the utility model discloses aim at every spark plug high-voltage line sheath via the manifold and blow, its heat exchange with the air on every side is accelerated, realizes the local cooling to the spark plug, therefore improved the spark plug because the sintering phenomenon that local heat dissipation is bad and arouse, prolonged the life of electrode, also improved the reliability and the sensitivity that the spark plug was igniteed simultaneously.
Description
Technical field
The utility model relates to the device that improves spark plug partial heat radiation on the CNG motor.
Background technique
The function of the spark plug on the CNG motor is that the high-voltage pulse that spark coil produces is introduced the firing chamber, and produces the indoor mixed gas of electrical spark ignition combustion between two electrodes.Because the burning of inflammable mixture makes and is in high-temperature high-pressure state in the cylinder, influenced by it, spark plug insulator will inevitably absorb heat, wherein the fresh inflammable mixture during by air inlet is taken away or is derived by centre electrode except that sub-fraction, major part is then passed to housing through copper washer up and down, and then passes to cylinder head by housing.So spark-plug body and cylinder head are gathered a large amount of heats, the electrode of spark plug will at high temperature produce carbon distribution, the reliability of influence igniting; The oxide etch meeting that the inflammable mixture burning is produced under the High Temperature High Pressure consumes the electrode of spark plug; The skirt section of spark plug also can stick together with cylinder cap owing to the bad generation sintering phenomenon of heat radiation when the dismounting spark plug; In addition, the high voltage wire sheath that spark plug tip connect also can eject from wiring terminal owing to the thermal expansion of inner a little gas of spark plug.This shows that the heat dissipation problem of spark-plug body and cylinder head is very crucial, and does not still have desirable solution at present.Therefore the device of designing spark plug partial heat radiation on a kind of CNG of improvement motor is very necessary.
Summary of the invention
The purpose of the utility model technology is to provide a kind of device that improves the spark plug partial heat radiation for the CNG motor.
For achieving the above object, the utility model adopts following technological scheme: the device that improves the spark plug partial heat radiation, comprise gas compressor, gas compressor power and compressed air hose, it is characterized in that gas compressor is driven by gas compressor power, the inlet of compressed air hose links to each other with gas compressor, the outlet of compressed air hose is arranged near the spark-plug cable sheath, and towards the spark-plug cable sheath.
In such scheme, compressed air hose is made up of house steward and menifold, and house steward's inlet links to each other with gas compressor, at house steward's tube wall upper edge house steward's axial setting and the corresponding menifold of spark-plug cable sheath, the inlet of menifold is communicated with house steward, and the spark-plug cable sheath is aimed in the outlet of menifold.
In such scheme, house steward arranges along the orientation of spark-plug cable sheath.
In such scheme, gas compressor power is water pump.
Because the utility model is aimed at each spark-plug cable sheath via manifold and is dried, quicken the exchange heat of itself and surrounding atmosphere, realization is to the part cooling of spark plug, thereby improved spark plug owing to the bad sintering phenomenon that causes of local heat radiation, prolong the working life of electrode, also improved the reliability and the sensitivity of plug ignition simultaneously.
