Abstract

This invention relates to an ignition plug by using all-ceramic electrically heating unit as the central electrode. It is composed of: the shell of the ignition plug (SIP), a side electrode (SE), a central electrode (CE), an upper insulation tube (UIT), a lower insulation tube (LIT) and a conducting electrode (CDE). The SIP, connecting SE, is equipped on the engine. The CE is equipped in the upper part of the inner hole of SIP, between its upper end and the SE is clearance. The CE comprises an external resistance layer (ERL), insulation layer (IL) and inner conducting layer (ICL). An interlinkage hole is at the upper end of IL, the partial material of ERL and partial material of ICL are inter linked through said hole. A receptacle of the CDE is at the lower end of ICL, the CED is in the receptacle. The UIT is at the upper part of the inner hole of SIP, as the LIT at the lower part. This invention ensures the stable burning of gas.

Description

With the full-ceramic electrically-heated body is the spark plug of central electrode
Technical field
Belong to spark ignition equipment technical field with the characteristics that are produced as of ignition energy.
Background technology
Prior art engine ignition spark plug, its central electrode are cold electrode.Weak point is when lighting combustion gas, because the temperature of cold electrode self is low, meeting absorption portion energy may cause having lighted suddenly extinguishing of combustion gas, and influence is igniting smoothly.
Summary of the invention
It is the spark plug of central electrode with the full-ceramic electrically-heated body that technical problem to be solved provides what can guarantee smoothly igniting.
The technical scheme that solves its technical problem is as follows: be the spark plug of central electrode with the ceramic electrically-heated body, comprise spark-plug body, the other utmost point, central electrode, go up insulated tube, following insulated tube and conductive electrode; The spark-plug body that metal material is made is contained on the engine and ground connection, and the endoporus of spark-plug body is divided into two sections, and endoporus hypomere internal diameter is greater than endoporus epimere internal diameter; The other utmost point is connected with spark-plug body; The central electrode of being made by full-ceramic electrically-heated body is contained in the endoporus epimere of spark-plug body, between its upper end and the other utmost point certain clearance is arranged, central electrode comprises the dispatch from foreign news agency resistance layer, insulating barrier and inner conducting layer, the dispatch from foreign news agency resistance layer, insulating barrier and inner conducting layer are made by conducting ceramic material, ecto-entad is the dispatch from foreign news agency resistance layer according to this, insulating barrier and inner conducting layer, an intercommunicating pore is arranged in the upper end of insulating barrier, the part material of dispatch from foreign news agency resistance layer is communicated with the intercommunicating pore of the part material of inner conducting layer by the insulating barrier upper end, in the lower end of inner conducting layer the conductive electrode jack is arranged, conductive electrode is contained in the conductive electrode jack; Conducting ring is adorned in the outside of the lower end of resistive layer outside; Last insulated tube is contained between the endoporus epimere of the epimere of central electrode and spark-plug body, and following insulated tube is contained between the hypomere and spark-plug body endoporus hypomere of central electrode; Heating voltage is added between conductive electrode and the conducting ring; The igniting high pressure is added between conductive electrode and the spark-plug body.
Dispatch from foreign news agency resistance layer, insulating barrier and internal resistance layer can be by conducting ceramic material Si 3N 4, Al 2O 3, Y 2O 3And MoSi 2Make.The constituent of inner conducting layer and weight proportion can be Si 3N 4: Al 2O 3: Y 2O 3: MoSi 2=(550-650): (50-70): (60-80): (800-2800); The constituent of dispatch from foreign news agency resistance layer and weight proportion can be Si 3N 4: Al 2O 3: Y 2O 3: MoSi 2=(550-650): (50-70): (60-80): (570-700); The constituent of insulating barrier and weight proportion can be Si 3N 4: Al 2O 3: Y 2O 3: MoSi 2=(550-650): (50-70): (60-80): (10-560).
Beneficial effect: be applied to the spark plug that engine ignition is used.Beneficial effect is, in ignition process, central electrode produces higher temperature by electric current, makes the combustion gas of having lighted keep stable burning, and the central electrode after the heating is difficult for carbon distribution simultaneously.
