Abstract
The utility model relates to a ceramic thin film sparking plug with two electrodes. A positive electrode is in tine-shaped, and a negative electrode is a closed coat. A layer ceramic plating layer is plated on the surface of each of the electrodes. The utility model can realize directional ignition, can burn quick and thoroughly, can enhance the economy and the power performance of a gasoline engine, and can reduce notably emission.
Description
The utility model relates to a kind of automobile engine spark plug.
At present, common spark plug two electrodes adopt a very square shape flat-top, another very single sheath is flat-shaped, two interpolar electric fields are stable, so can not form electron wind, its defective is because anodal side's shape flat-top igniting non-directional, the right side when time is left, can not guarantee that ignition point is in predetermined flame kernel all the time, so can not remain best burning coupling, the combustion position fluctuation is big.
The purpose of this utility model is to provide a kind of orientable igniting, and makes the mist electron wind ceramic membrane spark plug completely that burns.
The purpose of this utility model realizes in the following way:
This spark plug (1) top has two electrodes: anodal (2) and negative pole (3), wherein: anodal (2) are central electrode, are pointed, and negative pole (3) is an external electrode, are shaped as closed sheath, also have one deck ceramic plated layer (4) at electrode surface.
The material of ceramic plated layer (4) can be boron nitride or silicon nitride.
The utility model compared with prior art has following advantage:
This spark plug can be realized directed igniting, and ignition distance is big, firepower is strong, can make ignition point be in predetermined flame kernel all the time, so can keep best burning coupling and stable combustion position.In addition, the fuel mixture body forms a large amount of little eddy current before igniting, and combustion speed is fast, and burning is thorough, and pottery combines with ferro element can play catalytic action, makes the NO that produces in the combustion process

2, prevent sooting of the spark plug, prolong its useful life, improve dynamic property, the economy of gasoline engine and significantly reduce discharging.
The utility model is described in further detail below in conjunction with accompanying drawing:
Fig. 1 is the utility model structure chart.
In Fig. 1: (1) spark plug; (2) positive pole; (3) negative pole; (4) ceramic plated layer.
When two interpolars add high-tension electricity and do not puncture, because electric field is in imbalance state, electronics can be by negative pole to anodal high-speed motion, because electronic impact gaseous mixture molecule forms electron wind, the air-flow that is produced with piston compressed mixed gas produces wind speed difference and incorgruous bump, produces a large amount of little eddy current in the combustion chamber, but high-velocity combustion during igniting, and burning thoroughly, improved the heat efficiency and the dynamic property of engine, reduces oil consumption.
Ceramic plated layer can adopt the prior art of chemical vapour deposition (CVD) and PCVD to finish.
Claims (2)
1, a kind of electron wind ceramic membrane spark plug, this spark plug (1) top has two electrodes: anodal (2) and negative pole (3), it is characterized in that: anodal (2) are central electrode, be pointed, negative pole (3) is an external electrode, be shaped as closed sheath, also have one deck ceramic plated layer (4) at electrode surface.
2, spark plug according to claim 1 is characterized in that: the material of ceramic plated layer (4) can be boron nitride or silicon nitride.
